    Prioritizing improvements at a shopping mall using an IPA framework approach2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this thesis work is to develop a model which can aid in prioritizing which customer service that should be the focus of improvement, using the two parameters; customers’ judgment of importance and the current performance as perceived by the customer. The thesis work examines customer services within a shopping mall In Thailand. To fulfill the purpose, three research questions were stated:

    1. How important is each of the three customer services: safety & security, cleaning operation and guest service according to the customer in a shopping mall in Thailand.
    2. How do Thai customers rank the current performance of the three customer services: safety & security, cleaning operation and guest service in a Thai shopping mall?
    3. How can a model be developed to aid in prioritizing where to focus improvements by combining values of customers’ judgment of importance and current perceived performance of the three customer services?

    Methodology – The gathering of data was done by interviewing and observing personnel of different customer services. This information was then used in creating surveys for the customers of the shopping mall to answer questions regarding the importance and performance of each service. A model was developed based on theories and the data gathered from the case study was used to illustrate its functions.

    Findings – The result of the first two research questions provided data which was used as input in the model created. The model is based on several theories and uses a “percentage of max” value to enable comparison between values. The model limits the “actual improvement” received when suggesting an improvement of a certain percentage by taking different theories into account.

    Implications – The model is made solely based on theories regarding customer satisfaction and performance and should therefore be seen as a guideline for practical use. The model focuses on the relation between importance and performance without any consideration to costs or any other parameters which has to be investigated and taken into consideration by the management team.

    Research limitations – This thesis work has been based around a single case study of a shopping mall in Thailand which could limit its generalization. However the model is solely based on theory and the data from the case study has only been used to test the model. Thus, the model should be applicable for other similar companies as long as the same input data can be gathered. Further studies could be done regarding how costs can be applied to the model as well as how different measurements. For example, the relation between amount of customers and amount of workers can be used in combination with the model.

    Lean implementation in geriatric care in a municipal: A case study from Sweden2014In: Proceedings of 2014 International Conference on Technology Innovation and Industrial Management, 28th-30th May 2014, Seoul, South Korea, 2014, p. S4-87-S4-99Conference paper (Refereed)
    Abstract [en]

    Purpose: The aim of this research is to examine how lean has been implemented at geriatric care in a municipal department in Sweden, focusing on the experiences and challenges of the employees, together with the strengths and weaknesses of the lean philosophy.

    Design/methodology/approach: The primary method used was a case study with interviews and observations on spot, in combination with a literature study. All with the intention of defining and describing lean, its value, and how organizations generally apply lean.

    Findings: All sources of information have shown that there are many advantages with lean such as better communication and a better-organized workplace. In addition, lean tools help to eliminate non-value adding activities (waste). However, implementations also bring about issues and challenges such as the difficulty of creating a long lasting lean commitment. A lack of follow-ups and the decreasing demand for lean from the executives have been the main issues within the geriatric care. The next step might be to create a common organizational culture, which is permeated with continuous improvements, focusing on value-adding activities for the residents and others stakeholders.

    Originality/value: Very few studies have addressed lean implementation in geriatric care as well as in a municipal department.

    Lean Six Sigma strategy in telecom manufacturing2014In: Industrial management + data systems, ISSN 0263-5577, E-ISSN 1758-5783, Vol. 114, no 6, p. 904-921Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to elaborate, how the use of a joint-use strategy of Lean and Six Sigma can improve flexibility, robustness, and agility. Telecom manufacturing has been under tremendous change after dot.com bubble burst in the early 2000, and new competition has originated from Asia. Being successful requires now more than before, and joint-use of strategies is one option to survive.

    Design/methodology/approach – A single case study from a Swedish company operating in the telecom manufacturing was conducted. In particular, a Six Sigma project was followed and analyzed during 2002. However, the outcome of the Six Sigma project has been studied in longitudinal manner until 2014.

    Findings – The Lean Six Sigma strategy ensures flexible, robust, and efficient processes. However, to make them more agile in order to sustain in today's highly competitive environment, something more is required. This could include staff training, strengthening company culture and collaborating with key partners in the supply chain.

    Research limitations/implications – This study is limited to large company that usually has a lot of resources and choices where to put the strategic emphasis as well as has level of control of the supply chain operations. The situation could be very different in small and medium-sized companies and thus it may be more difficult to realize the Lean Six Sigma strategy in such environment. On the other hand, the processes in these companies are often less complex.

    Practical implications – This research provides guidance on how to manage the Lean Six Sigma strategy in order to ensure more flexible, robust, and efficient processes as well as how to perform a Six Sigma project in Lean environment, in a proper manner.

    Originality/value – This research provides guidance to companies regarding the applicability and properties of the Lean Six Sigma strategy. The paper will also serve as a basis for other companies and industries, on how to survive in difficult times.

    Total productive maintenance in support processes: an enabler for operation excellence2015In: Total quality management and business excellence (Online), ISSN 1478-3363, E-ISSN 1478-3371, Vol. 26, no 9-10, p. 1042-1055Article in journal (Refereed)
    Abstract [en]

    In order to stay competitive in today's marketplace, it is vital to reduce activities that do not create value. Lean production has in the last decade been seen as a philosophy to reduce non-value time. The office environment often presents a major improvement opportunity to reduce non-value time. Lean contributes positively to business performance applied in a manufacturing context and is also suggested to do the same in a service context. The purpose of the paper is to analyse and determine how total productive maintenance (TPM) can be applied within the support process and to identify effects from an employee and business perspective. A case study has been performed and a qualitative research approach was selected. Empirical data were gathered by using semi-structured interviews at one case company, but from several teams that had applied TPM. The result was then used as an inductive approach to explore how TPM can be applied in a support process. To implement and apply TPM within an office context, it should be structured in three steps (i) define, (ii) implement and (iii) sustain. TPM should be conducted as a part of the ordinary day-to-day work. The planning and discussions connected to TPM can be included in regular daily departmental stand-up meetings' involving everybody. The work with 5S and maintenance should also be a part of the TPM structure, connecting it as a system and not as an isolated activity. TPM can create value from both a business and an employee perspective. In the employee perspective, TPM reduces the risk of missing/forgetting areas of responsibility and creates more involvement. In the business perspective, objectives such as cost and quality are improved, but TPM also enables the reduction of waste.

    Abstract [en]

    Purpose: This study deals with warehouse management with an emphasis on vertical lift modules (VLM). The aim is to examine the effect of the implementation of VLM on a business's warehouse management. In order to obtain a result, the study has been based on the following questions:

     How was the warehouse management designed before the implementation of VLM?

     How is warehouse management designed after the implementation of VLM?

    Method: To be able to answer these questions, interviews with ten users of VLM performed. All users usually lift systems from the same manufacturer. Among the users who visited the interview sessions observations have been carried out to better understand how the stock handling of the user is configured. The results of the interviews and observations have since been compiled in the form of tables. This is to make it easier to compare and highlight the distinct differences of inventory management before and after implementation of the lifts. The study has only examined how the implementation of vertical lift module impacted inventory management, although another storage equipment acquired in connection with the implementation of VLM.

    Results:The majority of users have the same design at the warehouse as they were before the introduction of the VLM. Most have replaced shelf compartments storage and use the new storage equipment with the existing one. With the help of the lifts, users have also reduced transportation distances in the warehouse, which has resulted in faster retrieval times. Article Readers acquired in connection with the lifts have also affected the picking time for the better.

    Many of the users have chosen to implement a VLM due to lack of space in the warehouse. In cases where the user have not been able to expand its warehouse VLM have been deemed suitable alternatives. Users who have been interviewed agree that the lifts have been a positive investment, which in the end has also proven to be cost-effective. Users find that the lift saves time and, in some cases, reduces the required amount of workforce as a result of a significantly more streamlined warehouse management.

    Implications: Results from the study can be beneficial for companies that are looking to acquire VLM to its storage facility. The results can also help students gain a deeper understanding of how the change of storage equipment can affect a company's inventory.

    Abstract [en]

    Purpose – The aim of the study is to identify, from an operational and strategic perspective, the impact of a digital information system on SME in the logistics industry.Based on the purpose of the study, two questions have been formulated.

    • What effects can a digital information system provide on an information flow at an operational level?• What strategic benefits can a digital information system give?

    Method – A case study has been conducted on a small logistics company that manages, repairs and manufactures pallets. The data collection was conducted through interviews and observations. Based on the data collection, a literature study has been conducted where an inductive approach has been used. A comparison and analysis between the literature study and empirical data has generated the results of the study.

    Findings – With regards to operational and strategic perspective, a digital information system may have different types of impact on SMEs. From an operational perspective, a digital information system can have the following effects:• Operations can be reduced• Reduction of lead time• Enables increased quality of information and information may be available in real time• Creates prerequisites for forecasts, which in return creates a good basis for planning and decision making

    The benefits identified at a strategic level of implementing a digital information system are:• Competitive advantage• Decision can be taken based on correct information• Creates new opportunities• Better customer relations

    Implications – This study highlights the impact of digitization on companies and provides evidence that digitalization of information systems can lead to shorter lead times, reduced documents and safer information in the flows. The study's findings reinforce and confirm the existing theories that a digital information system can help a company to create more effective processes and a smoother management of its information. The case company illustrate a problem that more logistics companies may experience and where an information system can be a solution for easier management and more up-to-date information.

    Limitations – The purpose of the study is to investigate a company's information flow linked to a specific product category. The economic aspects of information management are not considered in this study.

    Market versus supply chain vs. supply chain competition: A systems approach to reconciling the perspectives for business2016In: / [ed] Lauri Ojala, Juuso Töyli, Tomi Solakivi, Harri Lorentz, Sini Laari, Ninni Lehtinen, Turku: University of Turku Press , 2016, p. 1-17Conference paper (Refereed)
    Abstract [en]

    Purpose

    The purpose of this paper is to propose an integrative account of market (economic) competition and supply chain vs. supply chain competition in order to discover how both perspectives of competition might fit together within the broader encompassing notion of business competition.

    Design/methodology/approach

    The paper explores the potential points of alignment between the two competition perspectives from their development through to their current standings. Literatures on the evolving supply chain vs. supply chain competition as well as market competition are thus explored.

    Findings

    Results show that the two perspectives of competition are more similar than expected and as such market competition and supply chain vs. supply chain competition may not be described as mutually exclusive alternatives to the concept of competition.

    Research limitations/implications (if applicable)

    The suggestions in this paper have implications for the discussion on how to deal with the competition interfaces (borders) that may be present in carrying out business as usual.

    Original/value

    The paper presents as one of the first studies of an integration of market competition and supply chain vs. supply chain competition, and thereby contributes to furthering our understanding of competition between supply chains and the different competition regimes that may exist within the business environment. This prospect is yet to be pointed out in literature.

    E-procurement beyond the buyer cost perspective2010In: Proceedings of the 22nd NOFOMA Conference, Kolding, 2010, p. 483-498Conference paper (Refereed)
    Abstract [en]

    Purpose – The objective of this paper is to provide and argue for a comprehensive view of eprocurement that involves both the buyer and suppliers and that goes beyond looking at mere cost reductions on the buyer side. More specifically, the paper describes benefits and barriers of implementing e-procurement solutions for both buyers and suppliers.

    Design/methodology/approach – This paper reports on a literature review combined with a case study. The case is a public organization in Sweden, which prepares to implement an eprocurement solution. Interviews were also conducted with a selection of suppliers to the case organization.

    Findings – In e-procurement literature, drivers and barriers are often viewed only from the perspective of a buying organization. Benefits are mainly cost-related for the buying organization, while barriers often include suppliers. It is proposed that benefits and barriers should include both buyers and suppliers. The literature review and the case study findingsform the basis for further investigation into this problem area.

    Research limitations/implications – This study focuses on a public organization in Sweden. Yet, it could have implications for many public or private organizations considering implementing e-procurement systems.

    Practical implications – This research suggest that organizations to a greater extent should take the supplier´s side into account when implementing e-procurement solutions.

    Originality/Value – The study highlights a full cycle view on e-procurement taking both buyer and supplier into account.

    Abstract [en]

    In the city of Jönköping problems with the irregular flow, erosions and transport of sediment materials are recurring in the brook Strömsbergsbäcken. The problems is somewhat caused by an increased flow of storm water in the brook, which leads to high flow peaks in some parts of the brook since the original furrow is not dimensioned for the increased amount of water. The purpose of this project work is to make ecological drainage management in urban environments with a high amount of storm water discharge more efficient. The objective with the report is to create valuable material of how to accomplish ecological drainage management in urban areas and that the report will be useful for future similar connections. To fulfill the objective, the following three questions have been designed as a significant part of the final project report:

    • How can the load on the general drainage system be reduced?
    • How can the pollution effects of storm water runoff in urban areas be reduced?
    • Which treatments are appropriate to enhance the ecological storm water management in Strömsbergsbäcken ?

    The methods that have been used to solve these questions are document- and literature studies, and also a case study.The thesis results shows that the storm water flows from four of the nine areas that has its outlets in Strömsbergsbäcken, need to be treated through some kind of a solution or method that delays the water flow. The treatment could be performed in the area, before the storm water reaches the storm water network, which leads to Strömsbergsbäcken. The storm water flows can also be reduced by treatments adjacent to the outlets in the brook, where the largest flow peaks occurs. For example an essential solution to decrease the flows in Strömsbergsbäcken is to reconstruct the old dam located near one of the outlets into a basin, which will delay the stormwater flows.

    Humanitarian Relief Organizations and Its Relationship with Logistics Service Providers: A case study of UNICEF during the Mozambique flood disaster 20132013Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Nowadays, humanitarian relief organizations are more and more present in people’s lives due to the number of recorded natural disasters increasing over the last 30 years. Although there are several actors involved in humanitarian aid, the need to integrate logistics service providers into humanitarian relief operations has been recognized. Howev- er, the literature lacks particular attention concerning the coordination roles and objectives between humanitarian relief organizations and LSPs during disaster relief operations.

    Purpose: The purpose of this study is to explore the relationship between UNICEF and its LSP(s) during disaster relief operations. More specifically, this study aims to understand the elements that drive, facilitate, constrain and affect the relationship UNICEF has with its LSPs.

    Method: A qualitative, exploratory research approach was used, using a real-context case study as the research design. The empirical data was collected through in-depth semi- structured interviews with four respondents representing both UNICEF and its LSPs.

    Conclusion: The researchers present a revised version of the conceptual framework used to conduct this research. One additional component was added to the list of compo- nents affecting the effectiveness of a relationship. In addition, some other influencers were discussed. This conceptual framework can be used to formulate an effective relationship between two humanitarian actors within disaster relief operations. Finally, forming a rela- tionship between UNICEF and its LSPs is nothing new. Recommendations for future re- search include investigating implementation efforts once a relationship is built, in order to improve disaster relief operations and save more lives.

    Abstract [en]

    Abstract

    Purpose – The purpose of this study is to examine the challenges that exist within thematerial handling process, to and from a department for service and maintenance at a hospital, and how the challenges can be managed to achieve a more efficient material handling process. In order to fulfill the purpose the following two questions where formulated:

    1. What challenges exist within the material handling process, to and from adepartment for service and maintenance at a hospital?

    2. How can the challenges be managed to achieve a more efficient materialhandling process?

    Method – To achieve the purpose of the study, a case study was conducted at Ryhov Hospital in Jönköping. The case study was conducted through interviews, observations and document studies. The collected data has been interpreted and analyzed against a theoretical framework and thus generated the study’s results.

    Findings – The challenges identified in the study have been divided into five different categories: lack of process efficiency, lack of information exchange, lack ofcollaboration, variations and individually dependent deficiencies. Tools to deal with the challenges include developing a more holistic view and developing a higher degree of standardization and routinisation. Additionally, the introduction of a coordinating transport organization is introduced, thus creating the conditions to simplify and streamline the material handling process, streamline information exchange, develop cooperation and make it easier to handle variations and individually dependent deficiencies.

    Implications – During the study the challenges for the material handling process in ahealth care context were divided into five different categories. The methods and tools used to manage the challenges have different traits and characteristics. While trying to make the material handling process more efficient it is important for each organization to take into account the challenges that are the most critical to improve their specific situation.

    Limitations – The aim of this study was to create a deeper understanding for the problem area by studying a case. A single case study, however, is an unsecure foundation for creating generalizable results. It had been desirable to make further case studies in other hospitals. The focus has also been on the material handling process to and from the service organization, and it could have been interesting to broaden the perspective to get more insights.

    Improvement of Automotive Article Placement and Workload Distribution in Warehousing2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose is to: Improve the efficiency of warehouses operations as well as reduce its workload imbalances by altering the warehouse layout and work zones at a storage area. This was done by answering the following research questions:

    • What is the current state of the sites efficiency and workload imbalances?
    • How can the warehouse layout be designed to increase the efficiency?
    • How can warehouse work zones be altered to reduce workload imbalances?

    Method – The purpose was achieved through a case study at a vehicle manufacturing facility. By studying established methods of efficiency, layout designs and workload imbalances, ways of improving the operations was discovered. The effects of these methods were then tested through the case.  

    Findings –There are two categories improving efficiency, namely increasing output or decreasing input. The study also provides examples of ways to do both, and verifies them at the case company. The focus of both methods is a decrease in travel distance which proved to be a reliable way of increasing efficiency.

    Workload imbalances can be decreased by sharing workload between the resources. The case shows the result of two different resources with unequal workload and discusses the trade-off between efficiency and workload equality.

    Implications – The practical implications of the study is guidelines for how efficiency can be increased and how workload imbalances can be decreased. The academic implications are verifications of the used theories.

    Limitations – This study focuses on a restricted part of the storage process, namely traveling. There are more processes which could be included to further benefit the overall efficiency, these have however been excluded to limit the scope. The study also uses a heuristic approach based on prior research which means that the optimal solution might still be unknown.

    Keywords – Efficiency, workload imbalances, storage management, family grouping

    Applicering av kundorderpunktsmodeller på utbildningar inom en konsultverksamhet2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this thesis is to describe the development process for educations within consulting with customer order decoupling point models commonly used within manufacturing operations. The purpose has been broken down into two parts:

    1. Objective: To describe the development process for educations within a consultancy.
    2. Objective: To position the development process for educations based on the customer order decoupling point models.

    Method – In order to meet the thesis purpose, a case study was conducted on the engineering consultancy Combitech AB in Jönköping. To provide a basis for the theoretical framework a literature study was performed. To collect empirical data a case study including interviews and a document study was conducted. The empirical data were then analysed against the theoretical framework, and through pattern matching the customer order decoupling points were positioned into the models. The analysis has helped to achieve the thesis purpose.

    Findings – The engineering process that was identified for the three educational categories lacked a standardized approach. Instead, programs were often individually designed and tightly tied to the individual consultants. The thesis shows that the two customer order decoupling point models from manufacturing operations varied in usefulness to visualize the degree of customer order management in the engineering process of a consultancy business. As a visualization tool the two-dimensional customer order decoupling point model was of limited value because it didn’t show much difference between the processes described. The model for the engineering and design process was more nuanced and worked better to indicate which activities in the engineering process that were customer order driven.

    Implications – The customer order decoupling point models are created for manufacturing operations that produce physical goods and by testing these models on a service, the model framework and function is challenged. This thesis has helped to cover a part of the identified theoretical gap in the use of customer order decoupling point models between manufacturing operations and service operations.

    Limitations – To help cover the theoretical gap the two-dimensional customer order decoupling point model can tentatively be further developed and fully customized for service operations. A person with an academic knowledge of service and customer order decoupling point theories could help create new theory in the field. It would also be interesting to investigate whether it is possible to combine the two customer order decoupling point models presented in this thesis.

    Inköpsorganisation och förbättringsförslag i ett medelstort tillverkande företag2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purchasing has a direct impact on a company’s profitability, which means that focusing on reducing purchasing costs can lead to large positive effects. The purchasing function in a company is usually organized in a hierarchical structure which depends on the challenges the company faces. One factor that affects the organization structure is what degree of centralization that is being used.

    Tenhults Pressgjuteri AB had the year 2011 sales of 90 million SEK and currently employs 75 people. The company has recently expanded significantly which has led to structural problems in the purchasing organization. Company directors have experienced that the purchasing organization is becoming more difficult to monitor and control and are considering a centralized purchasing organization.

    The purpose of this thesis is to investigate the purchasing organization at Tenhults Pressgjuteri which also includes applying theories developed for large companies. To fulfill this purpose, the following three questions have been formulated:

    1. What strengths and weaknesses are there in the purchasing organization?

    2. What opportunities for improvement are there in the purchasing

      organization?

    3. What degree of centralization for the purchasing organization is

      appropriate?

    The purchasing organization is spread among several departments. A total of 13 employees have been interviewed during this thesis.

    Responsibilities within the purchasing process are unclear due to changes in the company since it was founded. The decision to centralize the purchasing organization is made by management and not a necessity from the view of the employees. Many steps in the purchasing process are not performed properly. The main inadequacies are found where evaluation of both supplier performance and the purchase is made. Supplier selection is often based on price. The company has a high technical expertise among the employees.

    The company needs to create a structure in the purchasing organization. They need to develop strategies and tactics for purchasing and start evaluating purchases and supplier’s performance. The company should make use of the purchasing tools that are available and use the right competence for the right purchase. Finally, we recommend the company to continue to develop the areas of the purchasing that have been estimated to be acceptable to avoid that they are overlooked.

    Considering Tenhults Pressgjuteris goal to grow 15 % each year and the conditions that the company has, the mixed degree of centralization is estimated to be most appropriate. Some of the company’s purchases are moved to a central purchasing department while technically difficult items still remains at appropriate staff. This option provides a good opportunity for the company to work strategically with purchase and is considered viable.

    Abstract [en]

    Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity. The capacity prob-lem is due to time consuming set-up times, machine care and material supply which makes the plasma cutting machines utilization rate 37.5 %.The study’s purpose aims to maximize the material flow through the plasma cut-ting machine. In order to answer the purpose, two thesis questions are used: “How can increased machine time in the plasma cutting machine be achieved?” and “How can the ma-terial flow to and from the plasma cutting machine be improved so that the actual capacity can be increased?”To answer the thesis questions, the study had a deductive approach in which ex-isting theories has been applied to real life case.In order to streamline the plasma cutting machine and the processes directly re-lated to it, the material flow upstream, the material flow through and the material flow downstream of the plasma cutting machine has been mapped and analyzed. In order to maximize the flow of material through the plasma cutting machine, setup times must be reduced to increase the capacity.The plasma cutting machine requires maintenance by the operator at regular basis where the nozzles and other consumables in the plasma cutting machine burner must be replaced. A SMED-analysis has been undertaken which shows that the internal set-up operations should be converted to external set-up operations. Re-placement of nozzles and consumables should be an external set-up operation and this can be achieved by purchasing more burners.The plasma cutting machine also has access to unmanned production which will be able to increase the capacity, since it can be running after hours.The material flow upstream and downstream must be improved through better planning of cutting orders and with a more efficient return flow. Prioritizing mate-rial supply to the constraining resource is crucial to secure that material shortages do not occur in the plasma cutting machine.If the study proposed measures are implemented, the material flow through the plasma cutting machine will be maximized.

    Premium E-Grocery: Exploring Value in Logistics Integrated Service Solutions2009Conference paper (Refereed)
    Abstract [en]

    E-grocery is gradually becoming viable or a necessity for many families. Yet, most e-supermarkets are seen as providers of low value “staple” and bulky goods mainly. While each store has a large number of SKU available, these products are mainly necessity goods with low marginal value for hedonistic consumption. A need to acquire diverse products (e.g., organic), premium priced products (e.g., wine) for special occasions (e.g., anniversary, birthday), or products just for health related reasons (e.g., allergies, diabetes) are yet to be served via one-stop e-tailers. In this paper, we design a mathematical model that takes into account consumers’ geo-demographics and multi-product sourcing capacity for creating critical mass and profit. Our mathematical model is a variant of Capacitated Vehicle Routing Problem with Time Windows (CVRPTW), which we extend by adding intermediate locations for trucks to meet and exchange goods. We illustrate our model for the city of Istanbul using GIS maps, and discuss its various extensions as well as managerial implications.

    Abstract [en]

    Purpose – The purpose of this study is to investigate how working practices associated with routines and communication in a manufacturing company’s support processes can be quality assured, to ensure the ability of operational processes to maintain competitiveness. Based on the purpose, three questions have been formed:

     

    • What challenges associated with routines can be identified in the working practice of manufacturing companies support processes?
    • What challenges associated with communication can be identified in the working practice of manufacturing companies support processes?
    • How can challenges associated with routines and communication be managed to increase manufacturing company’s quality of support processes?

     

    Method – To answer the study’s questions and fulfill the purpose, a case study has been conducted at DS Smith in Värnamo. The case study has consisted of a single case study design for the first two questions, while question three was answered with the help of a multiple case design due to an internal benchmarking conducted at DS Smith in Mariestad. The empirical data consisted of interviews, observations and documentary studies. An analysis of the empirical data from DS Smith in Värnamo has been compared with the theoretical framework, as well as the collected empirical data from the internal benchmarking at DS Smith in Mariestad.

     

    Findings – An improvement in working practices in the supporting processes is necessary to improve the operational process of a manufacturing company. Routines and communication are two factors that affect the working practices in a support process, but also other parts of the company. Regarding routines, it is important for the management to take responsibility and ensure compliance with the routines. It is also important to ensure that they fulfill the purpose for which they are intended. Otherwise management should consider opportunities to update or clarify existing routines. Communication must work in all directions within the company, this applies both between employees within departments and between different departments. The management should appoint a person responsible for the transmission of information given to the right staff within the company. Poor communication and information sharing at the beginning of a process can lead to major consequences and impacts further down in the process.

     

    Implications – The results highlighted by the study are reinforced from existing theory of how routines and communication should work within an organization. The study’s results also show that these factors have an impact on a support process, which results in an impact on the operational processes. Some practical implications that the authors have formulated are: To create clear communication channels as well as defining responsibilities and appoint responsible ones.

     

    Limitations – Support processes in manufacturing companies have been perceived as a limited area theoretically. The theory found has mostly been very summarized and fundamental, which has limited the study from providing empirical data to previous theory or research on the subject.

     

    Keywords – Routines, communication, quality, support process, operational process, manufacturing company

    Kundorderstyrning och kundanpassning - ett kund- och leverantörsperspektiv2012In: Plans Forsknings- och tillämpningskonferens 2012: Logistik i praktisk tillämpning / [ed] Peter Berling, 2012Conference paper (Other academic)
    Abstract [sv]

    Under forskningsprojektet KOPeration visade sig grad av kundanpassning vara en viktig egenskap att beakta vid utformningen av lämplig grad av samverkan i leverantörsrelationen. Projektet omfattar sex svenska tillverkande företag från olika branscher och är inriktat på kundorderstyrning och leverantörsrelationer.

    Projektet var inledningsvis inriktat på att undersöka i vilken utsträckning som kundorder är verksamhetsdrivande och hur det påverkar leverantörsrelationer. Under projektet visade det sig dock att ytterligare en komplicerande faktor i leverantörsrelationer identifierats, nämligen brist på överensstämmelse mellan det tillverkande företagets perspektiv och leverantörens perspektiv på grad av kundanpassning av en viss produkt. Inom ett företag finns en logisk sekvens av kundanpassningsgrad från standardartiklar, via kundunika artiklar till kundorderunika artiklar. Denna logiska sekvens gäller dock bara inom ett företag. En artikel som av leverantören uppfattas som kundunik kan ingå i standardsortimentet hos kunden, eller tvärt om, vilket kräver en mer nyanserad analys.

    Denna brist på överensstämmelse mellan kundens och leverantörens syn på kundanpassningsgrad är viktig att identifiera eftersom spekulationsrisken i försörjningskedjan då kan fördelas på ett bättre sätt. Det innebär en låg risk att tillverka och lagerhålla standardartiklar på spekulation (mot prognos, innan en kundorder har mottagits), medan tillverkning och lagerhållning av kundunika, eller till och med kundorderunika, produkter innebär en hög risk om det utförs på spekulation. Mycket talar därför för att den aktör som upplever den lägsta graden av kundanpassning bör lagerhålla produkter när det finns olika uppfattning av grad av unikhet.

    I detta papper definieras teorigapet gällande brist på överenstämmelse av kundens och leverantörens perspektiv på grad av kundanpassning. Därefter belyses det praktiska problemet, dvs. vikten av att identifiera situationer med ett ”ologiskt” flöde av kundanpassningsgrad. Potentiella fördelar med att vara medveten om dessa ”ologiska” flöden exemplifieras med hjälp av en fallstudie hos Parker Hannifin i Trollhättan.

    Abstract [en]

    Purpose: On-time delivery is a concept that refers to the ability to deliver at agreed time. Several studies has shown that on-time delivery to customers is one of the most important competitive tools used by manufacturing enterprises. Internal on-time delivery is the ability to deliver between and within a company’s different sections at the right moment but is however a concept that is seldom being mentioned in research studies. The internal on-time delivery affects the external and is therefore an interesting subject to study. The purpose of this study is to increase the knowledge of how internal on-time delivery in make-to-order environments can be improved. Two research questions have been answered in order to fulfill the purpose:

    1.      Which causes may affect the internal on-time delivery in make-to-order environments?

    2.      How can the internal on-time delivery increase in make-to-order environments?

    Methodology: A study with a qualitative approach has been used to fulfill the purpose and to answer the research questions. Common theories has been used in order to achieve a necessary knowledge about the subject. Theories about different tools for improvement has been used to answer the second question. Empirical data has been collected through a single case study in a manufacturing cell. The case study consisted of observations, interviews and a time study. The empirical data that has been collected describes the surveyed manufacturing cell, its product and its process.

    Results: The first question has been answered with the use of collected empirical data and common theories. The found causes that affect the internal on-time delivery in make-to-order environments are: Enterprise resource planning systems does not portray real conditions, Priority control of manufacturing sequences is not being followed, Temporary bottlenecks occurs depending on mixed order entries, Cell layout can limit the control of the flow.

    These causes has together with theories about different tools for improvement been used to answer the second question. Eight different types of improvements has been mentioned in the case. A few of these methods are: Enterprise resource planning should portray real conditions, The priority control of the manufacturing sequence should be followed, Resources capacity may need to be increased.

    Discussion: It would be interesting if further research studies was made to gain more knowledge about causes that may affect the on-time delivery in make-to-order environments. It may be possible for manufacturing enterprises to use this studies structure to improve their own internal on-time delivery in make-to-order environments.

    Hantering av stokastiska variationer: Val av säkerhetskapacitetsbuffert baserat på kundorderpunktens position2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The study aims to map how the position of the order penetration point is related to companies’ choice to handle stochastic variations in capacity requirements through the use of safety capacity buffers. Hence, the research questions are:

    1. Which are the main safety capacity buffers used to handle stochastic variations in capacity requirements?

    2. How is the position of the order penetration point related to the choice of safety capacity buffers to handle stochastic variations?

    Method – A case study has been conducted in order to answer the research questions and thus includes a literature study, interviews and document studies. The interviews were conducted with seven respondents from six companies and the empirical data that emerged from the interviews and document studies were analysed together with theory from the literature study to reach the result of the study.

    Findings – The study has identified ten approaches to handle stochastic variations, two of which was not previously mentioned in the theoretical framework. The ten approaches have then been categorized into six safety capacity buffers based on similarities.

    After identifying the position of the order penetration point possible connections between the position of the order penetration point and choice of safety capacity buffers have been analysed to explore possible relationships. Three tendencies to connections have been identified but further studies are required to ensure the connections.

    Implications – The research area of handling variations in capacity requirements with a division in one capacity buffer and one safety capacity buffer is relatively unexplored. Exploring possible connections between the choice of safety capacity buffers and the position of the order penetration point could fill a gap of knowledge and theoretically contribute to further research within the area of safety capacity buffers. Learning of others’ experiences gives an increased understanding which can help companies to make more informed decisions that can lead to better performance, which is the practical contribution of the study.

    Limitations – The studies limitations lies in that only seven respondents from six companies were included in the study, were only one interview was conducted with each respondent. The number of used approaches and their connections to the order penetrations point could have been strengthened in case an increased number of respondents from different kind of companies had participated in the study. Thereby the connections’ generalizability could have been strengthened. Additionally more approaches probably would have been identified in case a greater width had been studied.

    In the study the total capacity have been handled as two separated parts to handle expected and unexpected requirements. The approach is relatively new and not established which can complicate and limit the ability for companies to apply the results.

    Kartläggning och förbättring av processer hos Aero Materiel.2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Aero Materiel är ett grossistföretag beläget i Jönköping med inriktning på låselement och har 20 anställda. Syftet med examensarbetet var att beskriva och förbättra processerna på Aero Materiel.

    En benchmarking genomfördes på barnkliniken på länssjukhuset i Jönköping som 2009 fick utmärkelse Svensk Kvalitet. För mer underlag till analysen har även en litteraturstudie gjorts där flera olika teorier om processorientering har studerats.

    Problemen vi identifierade var att företaget hade för många processer och de var inte strukturerade att dra nytta av processorienteringsfördelar. Aero Materiel har tio huvudprocesser definierade där endast ett fåtal är kundorienterade. Processerna är även uppdelade efter respektive avdelning och inte en enda går igenom två eller fler avdelningar.

    Vår slutsats är att företaget bör ha två huvudprocesser för att göra det mer hanterbart. Dessa är ”leverans av standardkomponenter” och ”leverans av anpassade komponenter”. De nya huvudprocesserna går rakt igenom organisationen och följer flödet mer naturligt. Vi rekommenderar att företaget utser processägare för respektive huvudprocess. Om Aero Materiel genomför våra rekommendationer tror vi att företaget blir mer processorienterat, vilket i sin tur gör företaget bättre förberett för fortsatt tillväxt och ökad förmåga att höja kvaliteten och minska kostnader.

    In-transit distribution as a strategy in a global distribution system2011In: International Journal of Shipping and Transport Logistics, ISSN 1756-6517, E-ISSN 1756-6525, Vol. 3, no 2, p. 198-209Article in journal (Refereed)
    Abstract [en]

    Distribution has become a key factor in today's logistics system due to companies' desires to achieve considerable economies of scale in production, achieved by focused factories, as well as customers' demands for shorter lead-times and customer adapted products. The purpose of this research is to investigate if the in-transit distribution strategy may offer companies a competitive advantage and may be used as a complement to the centralised distribution strategy and/or the decentralised distribution strategy. This study shows that the in-transit distribution strategy can give major competitive advantages by offering rather short lead-times for customers without having to store products locally in warehouses. This, in turn, gives lower warehousing costs, lower tied-up capital, a less interrupted manufacturing, and steady and continuous production volumes. In order to be successful with this strategy, it takes good planning, working closely with customers, good market knowledge, and an enterprise resource planning (ERP) system that is able to support the strategy sufficiently. Among these factors, low variation in demand as well as manufacturing output is required, and furthermore distribution lead time needs to be predictable.

    Supply Chain Planning in Automotive Sector: A Swedish Case Study2011In: Conradi Research Review, ISSN 1459-0980, Vol. 6, no 2, p. 33-54Article in journal (Refereed)
    Abstract [en]

    This research aims to enhance the current level of knowledge from supply chain planning (SCP) by analyzing the importance of collaboration, information exchange and a supporting information system in its successful execution. These are examined through a case study from international manufacturing company, which operates in automotive industry with its global manufacturing network. Research reveals that collaboration is a complex and important issue of SCP, and occurs simultaneously in vertical and horizontal dimensions. It is important to select strategic partners and to develop a structured work processes and routines. The main objective of collaboration is to determine common goals and objectives and to facilitate the exchange of information; these together drive the performance of a supply chain higher. A sufficient information system supporting the SCP is vital to facilitate collaboration, and information exchange between the different supply chain participants. However, currently in the case company quite many phases of SCP are completed without appropriate and integrated information systems and the process itself contains several manual phases.

    Abstract [en]

    Purpose – The purpose of this study is to increase the understanding of how the

    supply strategy of a manufacturing business can be affected by some competitive

    factors and the suppliers’ geographical location. In order to fulfill the purpose of this

    study the following three questions were formulated:

    1. How do the competitive factors: cost, quality, flexibility, delivery time and

    reliability get affected by the suppliers’ geographical placements?

    2. How do the competitive factors cost, quality, flexibility, delivery time and

    reliability affect the design of an organization’s supply strategy?

    Method – To fulfill the purpose, a literature study were conducted combined with a

    case study. The literature study was focused on how different competitive factors can

    be affected by a company supplier’s geographical location. The impact of how this

    can affect a business supply strategy was also investigated. The empirical study was

    based on document studies along with interviews conducted at the case company. The

    theoretical framework has been analysed against the empirical study.

    Findings – The competitive factors can be affected in different ways, depending on

    where the supplier is located, both in relation to the company but also depending on

    which geographic continent they are based on. Finally, company’s supply strategy is

    affected in a large extent by how they choose to prioritize their competitive factors.

    Implications – Theories and methods that are suggested to achieve an effective

    supply strategy are implementable on companies who use a multiple number of

    suppliers. To implement the result of this study, it is required that the company has a

    clear picture of which competitive factors that has the highest priority. It is required a

    profound knowledge of supply and supply strategies and further studies since the

    conditions can be different for every company.

    Limitations – This study has been conducted with help from a case company, whose

    production is located in Malaysia and head office in Kista, Sweden. Because of the

    long geographical distance, the communications has been limited which hampered the

    conducting of the study.

    Networks and capabilities as characteristics of logistics firms2011In: Industrial Marketing Management, ISSN 0019-8501, E-ISSN 1873-2062, Vol. 40, no 6, p. 1004-1011Article in journal (Refereed)
    Abstract [en]

    The research purpose of this paper is to describe and analyse how three basic types of logistics firms differ in terms of their core capabilities and network development as well as the effects of the difference. Based on the resource-based view and the industrial network approach, a conceptual framework is developed to differentiate logistics firms. Two case studies of logistics firms are used as examples to demonstrate how the framework can be used. Logistics firms have clear differences in capabilities and network focus. These firms follow different dominating logics of value creation that make them develop in different ways and think totally differently. This research enhances our understanding of the different logics of logistics firms and their interdependence. They are complementary and interacting in the logistics service supply chain. Moving between the basic types of logistics firms means changing the capabilities and network focus, which is costly and difficult. The conceptual framework can be used as a tool to comprehend multiple types of logistics firms. It also helps us to analyze related strategic moves.

    Investigation of Critical success factors for ERP implementation: A user perspective2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Due to the rapid development of globalization, increased competition has led to significant market changes. Enterprise resource planning (ERP) has been a crucial part of gaining competitive advantage, but implementing an ERP system have shown to be complicated and expensive. Hence, understanding the critical success factors (CSF) when implementing an ERP system is vital as it can provide a successful implementation. Previous research has mainly focused on the general perspective, whereas the user perspective towards the CSFs has been lacking. This thesis complements the research by concentrating on the operational user and their perception towards the importance of each CSF as well as in which implementation phase each CSF is essential. 

    Purpose: The purpose of this study is to investigate the CSFs of an ERP implementation from a user perspective and why these are important in different implementation phases. 

    Method: As this study adopted a qualitative approach, a multiple case study of three case companies was conducted with an inductive research approach. The empirical data have been gathered through semi-structured interviews. A theoretical framework has been used for the literature in this study. The empirical data was then analyzed and compared to the literature. By analyzing the data in a within-case analysis before combining the findings in a cross-case analysis, it enabled the possibility to compare and derive a conclusion covering all case companies. 

    Conclusion: The results of this thesis shows that users from the case companies believed that more users should be involved in the ERP implementation. Furthermore, two case companies believed each 13 CSFs to be critical in an ERP implementation, whereas one case company believed 12 CSFs to be important. Where the CSFs ‘minimum customization', ‘education and training,' ‘technical possibilities' and ‘performance measurement' were perceived to be essential in this study compared to previous research when users did not perceive these CSFs as important. Lastly, a first attempt at grouping the CSF with the phases of an ERP implementation was made. The findings from the cross-case analysis revealed that there is a shared perception across some of the companies of why the CSFs are essential concerning the specific phases.

    Service orientation in the air cargo handling industry: Understanding barriers and developing measures on how to move the air cargo handling industry towards a more service-oriented culture.2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Within 24 hours 100,000 planes take off, over 140,000 tons of air cargo is carried, and goods worth about USD 18.6 billion are transported all around the world. However, the air cargo sector lacks behind in terms of service orientation in the handling organizations which can become a significant factor in regards of competitiveness for companies operating in this industry.

    Purpose: The purpose of the thesis on hand is to assess the current organizational culture and status of service orientation of handling organizations in the air cargo industry, to find barriers affecting a service-oriented performance and develop measures on how to move towards a culture and attitude in which employees are aware that every single of their actions can potentially impact the customer.

    Method: A literature review of academic references, frameworks, and concepts serves as foundation of the thesis on hand. The research design applied is a mixed approach of both, qualitative in-depth interviews with specialists in air cargo handling as well as a quantitative handling employee survey. The qualitative data enables the researcher to study detailed insights whereas the quantitative data allows to collect a broad base of opinions.

    Findings: The findings show a discrepancy between the perceptions of service orientation when comparing the management level’s opinion with the point of view of the handling employees. Moreover, the type of culture most favorably for a service-oriented attitude is analyzed to be a family-type of organization combined with a hierarchical culture. Barriers hindering a service-oriented performance have been assessed and can be overcome by identified cultural change management measures such as special service orientation training.

    Conclusion and managerial implications: Service orientation has to be established within the organization on both, the personality traits and organizational facet. Moreover, handling employees have to be considered as internal customers that require attention, appreciation, and positive feedback to stay engaged with the customers. The recommendation for management is to first initiate change towards an adequate culture and then, enhance service orientation within the respective measures.

    Paper type: The present research is an exemplary case study of the company Lufthansa Cargo AG (region USA & Canada) operating in the air cargo industry in order to fulfill the purpose of the thesis on hand.

    The Importance of the Retailer for OEM Developing Innovative Products2011In: Conradi Research Review, ISSN 1459-0980, Vol. 6, no 2, p. 63-81Article in journal (Refereed)
    Abstract [en]

    The supply chain strategy research has generated many frameworks for matching the supply chain with the nature of demand, market, consumers, or products. Recently many companies have implemented innovative new product development processes in order to increase revenue. However, research on the importance of the retailers for an original equipment manufacturer (OEM) adopting a leagile supply chain strategy for innovative products, is scarce. Using the case study method, this research investigates the need of collaboration between an OEM and its retailers. This research aims to richen the knowledge about demand supply chain management (DSCM), and the coordination of demand and supply processes between companies in the demand-supply chain. This research shows that there are several measures that may be used to monitor performance, and that collaboration is important for the case company.

    A consumer driven business models´ impact on sourcing and inventory2011In: Proceeding of the International Conference on Technology Innovation and Industrial management, Oulo, Finland, 2011Conference paper (Refereed)
    Abstract [en]

    Increased competition in many markets has forced firms to adopt new business models. Oneway to differentiate from the competition is to develop products based on implicit consumerneeds that may be sold at a premium price. This research uses case study methodology toinvestigate a Swedish furniture wholesaler, and how their shift to a consumer driven businessmodel has affected sourcing and inventory. The research reveals that the high focus on thedemand-side of the company has had detrimental effect on the supply-side. Between 2004 and2009 the number of stock keeping units increased dramatically, and the sales increased with22%. Sourcing was affected since the order quantities became smaller, which lead to longerlead times in manufacturing. The inventory levels also increased, as did the averageinventory turnover. As the market dropped in 2008 due to the economical situation, the casecompany was not able to respond to the changes in demand. The main theoretical implicationis that the management of the demand- and the supply-side of the firm have to be coordinatedon macro level, the main practical implication is that managers needs to devote time to bothmanagement directions, and the main social implication is that differentiated supply chainstrategies may employ people closer to the consumption market.

    The Role of Consumer Insight in New Product Development and Its Impact on Supply Chain Management: A Swedish Case Study2010In: Innovative Process Optimization Methods in Logistics: Emerging trends, concepts and technologies / [ed] Thorsten Blecker, Wolfgang Kersten, Christian Lüthje, Berlin, 2010, p. 113-126Conference paper (Refereed)
    Abstract [en]

    This paper seeks to explore how a profound consumer understanding may influence the early stages of a new product development (NPD) process. The issue is examined through a qualitative single case study combined with a literature review. The case study shows how the NPD process is structured and executed in a Swedish furniture company as well as the role consumer insight plays in that process. Empirical data have been collected mainly from in-depth interviews with persons representing senior and middle management in the case company. The research reveals that consumer oriented, cross-functional NPD in the case company has a strong impact on internal collaboration, and aligns the goals between different departments and functions within the company. Despite inefficiencies on departmental level, effectiveness on company level is achieved. Early indications show an expected growth in contribution margins by 8 percentage.

    Linking Moral Disengagement to Supply Chain Practices2013In: World Review of Intermodal Transportation Research (WRITR), ISSN 1749-4729, E-ISSN 1749-4737, Vol. 4, no 2/3, p. 207-225Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to identify if and how supply chain practices are linked to moral disengagement techniques and thus might cause moral decoupling (MD). The research uses a literature review and multiple case study approach to investigate this issue. The literature review links moral disengagement to supply chain practices, while the case study observes the existence of the practices, and in what supply chain configurations those practices might arise. Identified configurations that might cause MD are suppliers and external partners responsible for upstream activities, division of tasks, aggregation of materials, auction-like settings, long supply chains, production in low-cost countries, production where people are not considered as equals, and configurations made to reduce costs.

    Transfer of responsibility between supply chains2017In: World Review of Intermodal Transportation Research (WRITR), ISSN 1749-4729, E-ISSN 1749-4737, Vol. 6, no 2, p. 130-140Article in journal (Refereed)
    Abstract [en]

    Responsibility for the environment, social, and economic issues is of rising concern for supply chain management. Even though it is acknowledged that responsibility issues extend across the entirety of the supply chain, some parts of the chain are still in need of attention. Much of the detected misconduct takes place at the beginning, or the end of the supply chain, but the end of one supply chain could actually be the beginning of another chain. Here, we shed light on the interface between such chains, an area that constitutes a blank space in research. Ship breaking is used as an empirical example, to explain one situation where materials and products at the end of their life are salvaged and enters new/other supply chains. Ship breaking has impacts on the environment and the workers, but seems to be disregarded of both the first and second supply chain. Highlighting the problem, we suggest three types of flows in and between supply chains. We also bring attention to the complexity of responsibility in, and especially between, supply chains.

    Viewpoints of adults with and without Autism Spectrum Disorders on public transport2015In: Transportation Research Part A: Policy and Practice, ISSN 0965-8564, E-ISSN 1879-2375, Vol. 80, p. 163-183Article in journal (Refereed)
    Abstract [en]

    Background: Public transport is low cost, allows for independence, and facilitates engagement and participation for non-drivers. However, the viewpoints of individuals with cognitive disabilities are rarely considered. In Australia, the prevalence of Autism Spectrum Disorders (ASD) is approximately 1% and increasing. Many individuals with ASD do not possess a driver's licence, indicating that access to public transport is crucial for their independence. However, at present, there is no research on the opinions of adults with ASD on public transport. Aim: To identify the viewpoints of adults with ASD regarding the barriers and facilitators of public transport usage and their transportation preferences, and to contrast these against the viewpoints of neurotypical adults. Methods: Q. method was used to identify the viewpoints of both participant groups on public transport. Participants consisted of 55 adults with a diagnosis of ASD and a contrast group of 57 neurotypical adults. Both groups completed a Q sort task which took place in either Perth or Melbourne, Australia. Results: The most prominent viewpoint indicated that both groups preferred to use public transport over driving and believed that it supported their independence. This viewpoint also indicated that both groups preferred to use electronic ticketing when using public transport. Interestingly, the second most prominent viewpoint indicated that both groups preferred to drive themselves by private car rather than use public transport. Discussion: It appears that the viewpoints of adults with and without ASD regarding public transportation were largely similar. However, questions arose about whether the preference for public transport in the ASD group may be more a result of difficulties obtaining a driving licence than a deliberate choice. The only barrier specified by adults with ASD related to crowding on public transport. Safety and convenience in relation to location and timing of services were barriers reported by neurotypical adults.

    EFFEKTIVISERING AV INKÖPSPROCESSEN VID KUNDORDERDRIVEN TILLVERKNING2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Purpose – The purpose of this report is to examine the challenges that exist in the purchasing process in companies with a customer order-driven manufacturing and how these challenges can be managed to achieve greater efficiency.

    Background - A company with a customer order-driven manufacturing is characterized by inaccessible buffers and inventory that can capture the variations and imperfections of the material flow. This leads to a number of challenges for a purchasing process as it is the process that regulates the flow of material.

    Metholodgy – To meet the purpose of the report a case study has been conducted in collaboration with Lidan Marine in Lidköping. Through observations and interviews within the case study, empirical data has been collected in order to compare and analyze it with the theoretical framework of the study. Based on this analysis the findings of the report were generated.

    Findings – Based on the empirical data and literature five challenges has been identified. These challenges are found throughout the entire purchasing process and are intensified in the absence of buffers. The identified challenges are; lack of communication, optimistic time assessment, unclear work process, time constraint and indistinct purchase planning. The report also presents approaches for addressing the challenges identified in order to achieve greater efficiency and, in turn, increased success for a company with a customer order-driven manufacturing.

    Conclusion - The authors believe that the basis of the case studys challenges is the lack of a holistic perspective. By obtaining an overall perspective, employees can see how the company's processes associats with each other. This would lead to a better understanding of various approaches and how these affect the company as a whole.

    Implications - The challenges identified are derived from a purchasing process perspective in a business with a customer order-driven manufacturing. The study focuses on a selected case study and it could therefore be other challenges that need to be investigated at other companies. However, the company must obtain an overall perspective before action can be taken.

    Keywords - customer order decoupling point, purchasing process, supply chain management, effective, process
