Abstract [en]

Industrialized house-building companies predefine parameters in platforms. In the strive to identify efficient information flow with automation and configuration, the design process requires a breakdown of the product structure of a building to digitally communicate between information systems. The level of predefinitions varies between industrialized house-builders according to market position, type of building processes, and maturity in business. The client decoupling point according to the predefinitions of house-building as a product is central for how and when production information is created. Bill of materials is a breakdown structure that visualize relations and the transformation between engineering, preparation, and production processes from a life cycle perspective. A case study at eight house-building companies was chosen with the aim to identify relations between the level of predefinitions and breakdown structures. House-building platforms with a high level of predefinition on layouts, components, and interfaces show a tendency to use less time in BIM-tools for engineering work and a high level of parameters in manufacturing configuration systems to prepare for production. Meanwhile, the opposite with low levels of predefinitions on components and interfaces focus on BIM-tools for engineering work with longer lead times. An interesting outcome is those with a high level of predefinitions in interfaces but lower levels on component dimensions. These companies have the ability to position their offer to a wide market with flexibility in the engineering work and need to communicate the high levels of interface parameters for the manufacturing sequence with a breakdown of the product together with architects.

Abstract [en]

The house building industry has been characterised as less productive compared to the manufacturing industry with numerous and challenging activities including a complex integration process. For the last 20 years, industrialised house building has gained increased research and industry attention and is identified as a potential way to improve the overall house building productivity. In the overall process, the design phase has been identified as the bottleneck with several disciplines which have to be coordinated to generate a design solution that meets various customer and market requirements. Many aspects of a building's performance depend on the decisions taken in the early design process. These decisions can have a substantial impact on the overall design, lead time, cost and quality of the final product. However, there are many other important factors which need to be considered by designers during the design phase. Less attention has been paid to the identification of these factors within the design phase of the industrialised house building. Thus, the main purpose of this paper is to identify challenges and outline the critical success factors to be considered in the design phase of the Swedish industrialised house building. Qualitative research was conducted in combination with literature reviews and multiple case studies linking three Swedish house building companies. Empirical data were gathered from 20 semi-structured interviews. The study identified common challenges in the house building industry and 20 critical factors that should be addressed in the design phase from both literature and practitioners view. The result shows that fixed production is crucial for identifying the critical factors rather than a building system. Also, many challenges identified from this study could be managed by developing a platform-based approach with support tools and methods for critical factors in the design phase.

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.

Abstract [en]

Modules are often considered the basis of product platforms by enabling a variety of product variants based on interchangeable modules. In this way, modules enable efficient utilization of resources through economies of scale. The purpose of this work is to improve the product realization process by introducing a new model for module classification that enable companies to structure their assets and formalizing them in the development system. The modules developed following this methodology contains both physical resources and non-physical resources that can be reused in a structured way, thereby improving the efficiency of the development process.

Abstract [en]

Mass customization and product individualization are driving factors behind design automation, which in turn are enabled through the formalization and automation of engineering work. The goal is to offer customers optimized solutions to their needs timely and as profitable as possible. The path to achieve such a remarkable goal can be very winding and tricky for many companies, or even non-existing at the moment being. To succeed requires three essential parts: formally represented product knowledge, facilities to automatically apply the product knowledge, and optimization algorithms. This paper shows how these three parts can be supported in engineer-to-order businesses through the concept of knowledge objects. Knowledge Objects are human readable descriptions of formalized knowledge bundled with corresponding computer routines for the automation of that knowledge. One case example is given at the end of the paper to demonstrate the use of knowledge objects. © 2019, Springer International Publishing AG, part of Springer Nature.

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.

Abstract [en]

A rapidly growing strategy in product design and manufacture, with great potential to improve customer value, is mass-customization. The main idea is to divide the product into modules that can be shared among different product variants. This will support a wide range of options for the end customer to select among, while an internal efficiency, similar to mass-production, can be achieved. This has been a success for many companies acting 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. The solution can then be manufactured in different quantities depending on the client’s need. For these companies, there is a strategic need for developing high quality engineering support to further utilize and exploit the information and knowledge produced during product development and to succeed with a strategy influenced by the principles of mass-customization. This has to include the implementation and management of systems enabling highly custom-engineered products to be efficiently designed and manufactured. One challenge when introducing such flexible support is to enable traceability of decisions taken, tasks executed, knowledge used and artefacts developed throughout the whole lifecycle of an individual product. In this chapter, it is shown that traceability can be achieved by introducing support for capturing, structuring and mapping between decisions and resulting outputs, such as geometrical building blocks, knowledge implemented as rules, and the argumentation for the selection, design and specification of these. Three examples are presented where the concept Design Description has been modelled based on an item-oriented, a task-oriented, and a decision-oriented perspective which show the generality of the Design Description concept. The three examples demonstrate how to use the Design Description to enable traceability in platform design, product design, and manufacturing development processes.

Abstract [en]

Transdisciplinary processes have been the subject of research since several decades already. Transdisciplinary processes are aimed at solving ill-defined and socially relevant problems. Many researchers have studied transdisciplinary processes and have tried to understand the essentials of transdisciplinarity. Many engineering problems can be characterised as ill-defined and socially relevant, too. Although transdisciplinary engineering cannot widely be found in the literature yet, a transdisciplinary approach is deemed relevant for many engineering problems. With this paper we aim to present an overview of the literature on research into transdisciplinary processes and investigate the relevance of a transdisciplinary approach in engineering domains. After a brief description of past research on transdisciplinarity, implications for engineering research, engineering practice, and engineering education are identified. In all three areas, the current situation is described, while challenges are identified that still exist. The paper ends with a research agenda for transdisciplinary engineering.
