    Supporting the utilization of a platform approach in the engineer-to-order supplier industry2017Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Manufacturing companies are continuously faced with requirements regarding technology novelty, shorter time to market, a higher level of functionality, and lower prices for their products. This is especially true of suppliers that develop and manufacture highly customized products within the automotive industry. It is not uncommon that a request for a new product or subsystem goes out to several suppliers and that the one that can deliver the product most quickly and at the lowest price receives the contract. It is therefore vital for any supplier to answer to quotation requests rapidly and with a high level of precision while also ensuring that company assets are used efficiently. Other issues that apply to suppliers in the automotive industry are heavily fluctuating requirements during development projects, each customer’s individual preferences, and the ever changing interfaces with the OEM product with which the supplier’s product is to be integrated. Platform strategies have been widely accepted in industry to serve a wide product variety while maintaining business efficiency. However, the challenge of applying a platform strategy at the supplier level in the face of the reality described above has not been fully investigated. Platform approaches tend to require a focused development of the platform, which in turn requires some knowledge about which future variants are to be derived from the platform. The research presented in this thesis investigates the state of practice in industry regarding the challenges, needs, and current use of platforms. To respond to the identified need, a platform approach is proposed that expands the scope of what a product platform has traditionally contained. This is undertaken to aid in the development of highly customized products when physical modules or component scalability does not suffice. The platform approach provides a coherent environment for heterogeneous design assets to be used in product development, supporting both the activity of designing and off-the-shelf solutions. The approach is based on identifying and modelling generic product items that are associated with descriptions governing their design. By describing the outcome of technology and product development like finished designs, design guidelines, constraints, etc., in a standardized format, the platform continues to evolve. To aid in using the platform approach, a support system called Design Platform Manager is introduced at a company active as a secondtier supplier in the automotive industry. The system enables the creation of generic product items that can be structured, instantiated, and associated with descriptions, which aids in realizing product variants. The aim of the platform approach and tool is to support the quotation and continued design processes by identifying valid knowledge to use as circumstances, such as requirement changes or new design iterations, warrant. The support tool and overarching model have been evaluated by company representatives, who reported good results.

    The Design Platform Approach –Enabling platform-based development in the engineer-to-order industry2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Manufacturing companies are continuously faced with requirements regarding technology novelty, shorter time to market, a higher level of functionality, and lower prices on their products. This is especially the case for companies developing and manufacturing highly customized products, also known as engineer-to-order (ETO) companies. The traditional view of the product lifecycle introduces the customer only at the sale and distribution phase, which is often concerned with identifying and transferring customer needs into fixed specifications that guide the development of end-consumer products. In the ETO industry, however, the customer is involved already at the scoping and quotation stage, and a significant amount of engineering needs to be performed for every customer order. Thus, ETO companies cannot work according to the traditional model described above since specific requirements are set directly by the customer, or a detailed requirements specification is missing and must be developed in cooperation with the customer. It is not uncommon that products are developed in joint ventures with the customer and run for several years, during which requirements change.

    Product platform approaches have been generally accepted in the industry to serve a wide product variety while maintaining business efficiency. However, how to apply a product platform approach in ETO companies that face the reality described above is a challenge. Product platform approaches tend to require focused development of the platform, which, in turn, requires some knowledge about the future variants to be derived from the platform. The research presented in this thesis investigates the state of art and practice in the industry regarding the challenges, needs, and current use of product platforms. To respond to the identified need, a product platform approach is proposed that expands the scope of what a product platform has traditionally contained. The purpose of this proposal is to aid the development of highly customized products when physical modules or component scalability do not suffice. The resulting approach, the Design Platform Approach (DPA), provides a coherent model and methodology for heterogeneous engineering assets to be used in product development, supporting the activity of designing and existing solutions. The approach is based on identifying and modelling generic product and process items, which are the generic building blocks of the product, its structure, and the process of designing them. The generic product and process items are associated with the generic assets governing their design. By describing engineering assets that are the outcome of technology and product development, such as finished designs, design guidelines, constraints etc., in a standardized format, the DPA successively evolves.

    This thesis outlines the DPA in detail and presents cases of applications that have focused on different aspects of the approach. Tools to support the DPA are presented and evaluated in different kinds of industries along with the specific methods used and literature summarization.

    Towards a Platform Approach Supporting the Interface Between Technology - and Product Development2016In: Proceedings of the DESIGN 2016 14th International Design Conference, Dubrovnik, May 16-19, 2016. / [ed] Marjanović, D., Štorga, M., Pavković, N., Bojčetić, N., Škec, S., The Design Society, 2016, p. 1987-1996Conference paper (Refereed)
    Abstract [en]

    The separation of technology development (TD) and product development (PD) is adding to the challenge that suppliers face. They are to conduct long term TD and at the same time tailor products when the order arrives. This paper proposes a platform approach in order to describe some conceptual knowledge. An example from the automotive business where early simulations of concepts are performed during TD is presented. The focus is on how these simulations can support the transfer of knowledge from TD to PD and how they are to be described in order to communicate the technology’s ability to adapt.

    Creating an ability to respond to changing requirements by systematic modelling of design assets and processes2017Conference paper (Refereed)
    Abstract [en]

    System suppliers, e.g. original equipment suppliers, are important for the success of many products. They design a unique solution, often in close collaboration with other companies, based on different product concepts and/or core technologies. The solution can then be manufactured in different quantities depending on the client’s need. High level of customization is required as the interfaces are not standardized, the performance is not negotiable, requirements are not initially fixed and the specific system interacts with, is affected by, or affects other systems that are simultaneously developed. A system supplier commonly designs and manufactures solutions for different OEMs and must support many models and variants in their product portfolios. Efficiency, short lead-time, continuous technology development, and adaptability are essential for the competitive edge. A product platform approach has been a success for many companies to enable variety at low cost, however, it is not applicable for system suppliers. This work describes the result from a case study where a platform approach enabling a new way of structuring, publishing and managing design assets and processes was introduced at a company with the purpose to improve the ability to respond to changing requirements in the quotation process and the subsequent product development activities.

    Modeling of transdisciplinary engineering assets using the design platform approach for improved customization ability2018In: Advanced Engineering Informatics, ISSN 1474-0346, E-ISSN 1873-5320, Vol. 38, p. 277-290Article in journal (Refereed)
    Abstract [en]

    Original equipment suppliers (OES) that develop unique products are continuously faced with changing requirements during both the quotation and product development processes. This challenge is a different reality from companies that develop off-the-shelf products for the end consumer, which use fixed specifications and where product platforms have been a strong enabler for efficient mass customization. However, product platforms cannot adequately support companies working as OES. The reason is that a high level of customization is required which means that interfaces cannot be standardized, the performance is not negotiable, requirements are not initially fixed, and the specific system interacts with, is affected by, or affects other systems that are simultaneously developed in a transdisciplinary environment. The design platform (DP) approach provides a coherent environment for heterogeneous and transdisciplinary design resources to be used in product development by supporting both designing and off-the-shelf solutions. This research describes the introduction, application and further development of the DP approach at an automotive supplier to support the development of customized solutions when traditional modularity or platform scalability do not suffice. A computer tool called Design Platform Manager has been developed to support the creation and visualization of the DP. The support tool has a connection to a product data management database to link the platform model to the various kinds of engineering assets needed or intended to support variant creation. Finally, the support tool was evaluated by the case company representatives showing promising results.

    Supporting the modelling and managing of relations in the design platform2019In: Proceedings of the 22th International Conference on Engineering Design (ICED), 5-8 August, Delft, The Netherlands, Cambridge University Press, 2019, Vol. 1, no 1, p. 3001-3010Conference paper (Refereed)
    Abstract [en]

    A common strategy which has in many cases become a necessity in product developing companies is to apply platform thinking to some extent. Engineer-to-order (ETO) companies are firms that need to invest in a significant amount engineering time in each product ordered by customers. These companies have in the past been known to not be fully able to apply platform strategies. An area of concern to product development is the design and manufacture of machine tools aimed for part manufacturing which is a large investment and a critical bottle neck. As a response to these challenges the design platform (DP) concept was developed which is founded on the re-use of company assets. This paper aims to investigate the application of the DP in a company designing and producing unique high-pressure die casting tools for different applications and customers. To enable companies of this character to utilize platform thinking to a higher degree and thus increase the efficiency in product development, a focus is set on modelling and managing relations within the DP. In addition, a PDM system setup is proposed together with an integrated support application for the realisation in industry.

    The design platform – a coherent platform description of heterogeneous design assets for suppliers of highly customised systems2017In: Journal of engineering design (Print), ISSN 0954-4828, E-ISSN 1466-1837, Vol. 28, no 10-12, p. 599-626Article in journal (Refereed)
    Abstract [en]

    Companies developing highly customised products are continuously faced with fluctuating requirements during the early and late stages of the product development (PD) process. This differs from companies that develop end-consumer products, which uses fixed specifications and where product platforms have been a successful enabler for efficient customisation. However, in the past, product platforms have not been able to fully support companies working in an engineer-to-order business environment. This article outlines the results from a three-year collaborative research project between academics within the area of engineering design and practitioners from the engineer-to-order industry. The research introduces a design platform (DP) that aims to support the development of customised products when traditional platform concepts do not suffice. The platform approach provides a coherent environment for heterogeneous design assets to be used in PD by supporting both the design activity and the finished solutions. The needs and abilities regarding such a platform were investigated through a series of interviews and workshops at four companies. Then, the DP was modelled and support tools were developed. Finally, company representatives evaluated the complete DP and its applications, reporting promising results.

    Exploring the design platform in industrialized housing for efficient design and production of customized houses2019In: Transdisciplinary engineering for complex socio-technical systems: Proceedings of the 26th ISTE International Conference on Transdisciplinary Engineering, July 30 – August 1, 2019 / [ed] K. Hiekata, B. Moser, M. Inoue, J. Stjepandić & N. Wognum, Amsterdam: IOS Press, 2019, p. 125-134Conference paper (Refereed)
    Abstract [en]

    Industrialized house-building (IHB) is a sector offering unique products by adopting an engineer-to-order (ETO) strategy. Customer satisfaction is achieved by adaptation of product solutions and the fast-paced introduction of new technology in combination with short lead-times and cost-efficient production. Product platforms is acknowledged as a strategic enabler for mass customization and increased competitiveness. The strategy has been a necessity in the mechanical industry for several decades. However, for IHB, platforms have only gained interest in recent years. In general, ETO companies struggle with adopting the common product platform approach, set by pre-defined modules and components. Predefinitions require standardization of the product offer which reduces the customization ability which is regarded as a competitive edge. The Design Platform (DP) approach was developed aimed to support ETO companies by utilizing different types of engineering assets in a coherent transdisciplinary model enabling efficient customization. The long-term aim of this work is to investigate and support the DP applicability in IHB to increase efficiency in development and delivery. For this article, data were gathered from a single case study, including workshops with company representatives combined with interviews and document analysis. Based on the data analysis, engineering assets were identified and characterized. Further, a conceptual PLM solution is proposed and outlined to support the DP application combined with the assets. The results suggest that a PLM system can host parts of the DP and that it is applicable in IHB.

    A platform model for suppliers of customized systems: Creating an ability to master fluctuating requirements2016In: Proceedings of the ASME 2016 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference, IDETC/CIE 2016, Charlotte, August 21-24, 2016., 2016Conference paper (Refereed)
    Abstract [en]

    Companies developing highly customized products within the supplier industry are continuously faced with fluctuating requirements during both the quotation process and continued development. This research proposes a platform approach to aid suppliers when modularity or platform scalability do not suffice. The platform approach, Design Platform, focuses on descriptions that not only contain information about tangible components and systems but also information, knowledge and methods supporting the actual design of the product. A support system called Design Platform Manager has been developed to aid in using the platform approach and is introduced at a supplier active in the automotive industry. The system enables creation of generic product items that can be structured and instantiated to become product variants as well as Design Elements that are blocks of knowledge that describe a design or supports the activity of designing. A first evaluation is made that overall shows good result according to the company representatives.

    Introducing Design Descriptions on Different Levels of Concretisation in a Platform Definition2015In: Product Lifecycle Management in the Era of Internet of Things / [ed] Bouras, A., Eynard, B., Foufou, S., Thoben, K.-D., Springer, 2015, p. 800-810Conference paper (Refereed)
    Abstract [en]

    Product platforms has been widely accepted in industry as a means to reach both high product variety while maintaining business efficiency. For suppliers of highly customised products, however, the development of a platform based upon predefined modules is a challenge. This is due to the large differ-ences between the various systems their products are to be integrated into and the customer's individual preferences. What is common for most platform descriptions is the high level of concretisation, such as predefined modules, they are built upon, but how can companies act when that is not possible? Are there other principles that can be used for the definition of a product platform? This paper presents a concept to incorporate other types of descriptions of different levels of concretisation into a product platform. Parts of the concept has been realised in a computer support tool and tested at a case company in order to improve their quotation process.

    Managing Fluctuating Requirements by Platforms Defined in the Interface Between Technology and Product Development2014In: Advances in Transdisciplinary Engineering: Moving Integrated Product Development to Service Clouds in the Global Economy / [ed] Cha, J., Chou, S.-Y., Stjepandić, J. , Curran, R., Xu, W., Amsterdam: IOS Press, 2014, p. 424-433Conference paper (Refereed)
    Abstract [en]

    Product platforms play an important role for the efficient customisation and variant forming of products in many companies. In this paper four different companies ranging from OEM to B2B suppliers have been interviewed on how they engage in technology and product development, create and maintain product platforms and how they respond to the changing requirements on the platforms and on the products and product families derived from them. The objective is to find how product platforms are used to meet the demands of efficient product customisation. The companies all have identifiable product platforms and established processes for product development. However, there are differences in how they define technology development, how the platforms are created, maintained, replaced and what the platforms contain. The introduction of new technology into the platforms and how the platforms are used from a Lean product development perspective has been of interest in the survey as reported in the paper.

    Abstract [en]

    For many companies, it is a challenge to balance product variety and cost, i.e. external and internal efficiency. Product platforms has been the dominant solution for a business targeting mass-customization. The main idea is to dived the product into modules that can be shared among different product variants. This has been a success on the consumer market, however, many manufacturing companies are engineer-to-order (ETO) oriented, such as original equipment suppliers (OES). They design a unique solution, often in close collaboration with other companies, based on different product concepts and/or core technologies. For these companies, there is a strategic need for a platform model influenced by the principles of masscustomization, although, not limited to only include modules. In this work, a novel platform model, called Design Platform is described. The model has been developed and applied in cooperation with four companies. The Design Platform provides a coherent environment for management of heterogeneous design assets to be used in product development and supports an improved ability to master fluctuating requirements and systematic introduction of new technologies.

    Simulation ready CAD-models as a means for knowledge transfer between technology development and product development2015In: Proceedings of the International Conference on Engineering Design, ICED, Vol 6: Design Methods And Tools - Pt 2 / [ed] Weber, C; Husung, S; Cantamessa, M; Cascini, G; Marjanovic, D; Graziosi, S, Glasgow, Scottland, UK: The Design Society, 2015, Vol. 6, p. 195-205Conference paper (Refereed)
    Abstract [en]

    Manufacturing companies tend to separate technology development (TD) from product development (PD) as has been devised by research within the field of innovation management. When a technology is ready it somehow has to be made available to the PD teams so that the engineers working in PD projects can adapt the new technology into new products. The question is how that work can be supported. The ultimate goal of the research presented in this paper is to develop methods and tools to assist the knowledge transfer between TD and PD with a focus on supporting the actual use of the new technology in PD. This paper presents an industrial case along with a proposed method to achieve this. The TD and PD processes in the case company were reviewed with focus on how simulation models evolve over time and how they are used for different purposes. It was discovered that simulation ready CAD-models can be used to transfer the output from TD to PD.

    Modularisation in two Global Product Developing Companies: Current State and Future Outlook2018In: Proceedings of NordDesign: Design in the Era of Digitalization, NordDesign 2018, Linköping: The Design Society, 2018Conference paper (Refereed)
    Abstract [en]

    Modularisation and platform strategies enable efficient utilization of resources through economies of scale and are therefore increasingly important for manufacturing companies. On the product side, modules are often considered the basis of product platforms by enabling a variety of product variants by combining interchangeable modules into different products. On the process side, modularisation enables faster and cheaper development of new product variants by reusing physical components, interfaces, and production equipment.

    The benefits of product platforms and modularisation have led two global product developing and manufacturing companies to initiate research projects within this field. The companies have previously made unsuccessful attempts to implement modularisation founded on a componentbased approach and the firms are now searching for other methods to get the benefits of modularisation.

    This paper describes the initial state of practice in modularisation and product platforms in the two companies in their attempts to move from a purely physical approach to modularisation into the universal view that is presented in the Design Platform approach. Here, a platform is viewed as an evolutionary entity involving several company assets such as processes, knowledge, methods, and relationships which are essential to gain the benefits of platforms also in the development phase. The Design Platform contains various concrete resources such as the geometry of physical components, but also inhomogeneous resources such as design rules, processes, methods and design automation.

    The results point to specific barriers that the companies experience when trying to adopt a modularisation strategy. Several barriers are experienced by both companies while some are specific for one of the companies. Through several workshops, the concepts of the Design Platform and a flexible view on modularisation are introduced, and their possibilities are elaborated and appreciated by the workshop participants.

    Supporting Design Platforms by Identifying Flexible Modules2017In: 21st International Conference on Engineering Design (ICED17): Vol. 3: Product, Services and Systems Design / [ed] Anja Maier, Stanko Škec, Harrison Kim, Michael Kokkolaras, Josef Oehmen, Georges Fadel, Filippo Salustri, Mike Van der Loos, The Design Society, 2017, p. 191-200Conference paper (Refereed)
    Abstract [en]

    One way for firms to stay competitive is to adapt a platform approach. In product platforms, modules are used as exchangeable design blocks to create a variety in product performance. This is a proven way to get advantages of scale in production by reusing physical parts and investments in manufacturing. To ensure exchangeability between modules, interfaces between modules must be well defined. Hence, from this point of view, there is no such thing as flexible modules. In this research, flexibility refers to the idea of identifying strategic portions of the platform where flexibility is needed and to create the modular division in a way that the assigned modules are de-coupled in theses areas. The presented approach shows how the Design platform concept can be extended by the introduction of flexible modules. These support the Design Platforms by allowing areas of strategic importance to be more flexible and thereby enable room for uncertainties such as fluctuating requirements and future technical development.

    Introducing Inserts for Die Casting Manufactured by Selective Laser Sintering2018In: Global Integration of Intelligent Manufacturing and Smart Industry for Good of Humanity / [ed] Dušan Šormaz, Gürsel Süer, F. Frank Chen, Elsevier, 2018, p. 309-316Conference paper (Refereed)
    Abstract [en]

    The advances in additive manufacturing (AM) for high grade steels has in some cases made it possible to manufacture die inserts for demanding processes like high pressure die casting (HPDC). However, several challenges remain before this becomes commonplace. There is still a need of secondary manufacturing steps on the insert after printing. Also, extensive design changes must be made on the die inserts to fully utilize the advantages of AM. Further, the die insert is only one of many parts needed in the die assembly. Much of the die manufacturing will still be done by conventional methods. In this paper, several companies involved in the manufacturing and use of dies for HPDC have been interviewed on that they think is the future role of AM in their business. The result is that the effect of just printing the inserts would will be quite limited at present. Bringing down the time spent on die manufacture is important since that time then could be spent on improving the manufacturability of the parts.

    Early stage assessment of the inspectability of welded components: A case from the aerospace industry2016In: Proceedings of the 7th International Swedish Production Symposium, 2016Conference paper (Refereed)
    Abstract [en]

    This paper proposes a method to indicate potential problems when planning dye penetrant and x-ray inspection of welded components. Inspection has been found to be an important part of the manufacturability evaluation made in a large CAD-based parametric environment for making multidisciplinary design simulations in early stages of design at an aircraft component manufacturer. The paper explains how the proposed method is to be included in the design platform at the company. It predicts the expected probability of detection of cracks (POD) in situations where the geometry of the parts is unfavourable for inspection so that potential problems can be discovered and solved in early stages. It is based on automatically extracting information from CAD-models and making a rule-based evaluation. It also provides a scale for how favourable the geometry is for inspection. In the paper it is also shown that the manufacturability evaluation need to take into consideration the expected stresses in the structures, highlighting the importance of multi-disciplinary simulations.

    Introducing Welding Manufacturability in a Multidisciplinary Platform for the Evaluation of Conceptual Aircraft Engine components2017In: International Journal of Product Lifecycle Management, ISSN 1743-5110, E-ISSN 1743-5129, Vol. 10, no 2, p. 107-123Article in journal (Refereed)
    Abstract [en]

    Computer simulations play an important role for evaluating designs in an early stages leading to that more informed decisions can be taken and thereby reducing the risk of costly re-design. In this paper, a platform currently in operation at aeronautical company for doing extensive automated multiobjective design parameter studies on conceptual designs of aircraft engine components is studied. In the paper, an extension of the capability of the platform into making a rule-based evaluation of the welding manufacturability of the conceptual designs is proposed. The extension is tested by a prototype system at the air-craft manufacturer showing the relation between the design parameters and the manufacturability of the components. The results are presented as a manufacturability index showing what trade-offs with other performance criteria of the engine that can be made. It is shown that the manufacturability evaluation can be integrated in the knowledge value stream and supports a set-based concurrent engineering approach in the company.

    Manufacturability assessment in the conceptual design of aircraft engines – building knowledge and balancing trade-offs2015In: Product Lifecycle Management in the Era of Internet of Things / [ed] Bouras, A., Eynard, B., Foufou, S., Thoben, K.-D., Springer, 2015, p. 407-417Conference paper (Refereed)
    Abstract [en]

    This paper addresses the automated assessment of manufacturability of air-craft engine components in the early stages of design, focused on the welding process. It is a novel part of a multi-objective decision support tool for design evaluation, currently running at a manufacturer of jet engine components. The paper briefly describes the tool and how it impacts the product development process. Further, the paper presents an integrated method for manufacturability assessment by finding welding processes that complies with all geometrical and other constraints found in the CAD-models of the conceptual engine. Here, preferences made by manufacturing engineers serves as a base for a manufacturability index so that different parameter settings in the CAD-models can be compared to find the best parameter settings, considering the trade-off with other performance criteria’s of the engine.

    Managing Risk in the Introduction of New Technology in Products2015In: Journal of Aerospace Operations, ISSN 2211-002X, Vol. 3, no 3-4, p. 167-184Article in journal (Refereed)
    Abstract [en]

    In this paper interviews with staff involved in product development from four different companies is presented. The objective is to find out how the companies manage the technical risk of introducing new technology in products and how they prepare for meeting changing requirements from customers. The companies originates from aerospace, automotive and production engineering. Based on the results of the first study, a case study was carried out at the aerospace company. The studies shows that, the introduction of new technology varies with the risk of failure in the validation of the products. Companies that easily can revert back to the former technology is more risk taking. The types of products and the companies’ place in the supply chain has an impact on technology introduction and requirements handling. The companies have strategies for developing requirement specifications prior to the start of the project. This is most elaborate at the aerospace company where a thorough concept evaluation clarify possible variations in requirements.
