Abstract [en]

Design of sheet metal forming tooling is currently based on that experienced tooling designers with good knowledge of how stamping tools previously have been designed and operated in production, apply their knowledge when making a new design. For retrieving former designs, they often need to rely on their good memory. In this paper, an automatic method for retrieving relevant former cases is presented. A major challenge is defining the similarity between the current and the former cases i.e., finding the relevant parameters to include in the CBR (Case-based reasoning) search. This is here addressed by using CAD model parameters both from former components and the tooling for their production. By interviewing tooling designers in industry, a set of relevant parameters has been identified. To arrive at the correct weight of each parameter, a genetic algorithm has been used to optimize the search results. This resulted in a quick and automated way of retrieving the most relevant former cases and presenting them to the designer. The method has been tested on actual cases with promising results. This has the potential of making sheet metal part and tooling design less reliant on memory and experience.

Abstract [en]

The production preparation process (3P) enables collaboration between design and production engineers during product development but its efficiency is limited by the abundance of documentation of manufacturing constraints and capabilities. Empirical studies showed that use of production requirements can increase the efficiency of 3P, however, the support for production engineers to capture and share production requirements is scarce. A method to support production engineers in identifying, defining, structuring and sharing production requirements and collaborating with design engineers is presented. The method has three major parts - focus areas and requirement categories, a worksheet for production requirements capturing and prioritization, and a workflow for using the worksheet. The method was developed in collaboration with practitioners and contributes to the existing knowledge by providing production engineers with a structured way of working with production requirements. Evaluation of the method in the case company showed its usability when developing product variants and that additional work is needed to support the development of new product families and assembly lines.

Abstract [en]

Industrialized housebuilding (IHB) is a sector within the construction trade where product platforms have been introduced from the mechanical industry to manage the product architecture and allow mass customization. The aim of this study is to analyze product development projects connected to the product platform and the production. For IHB, the backbone is a technical platform where components are designed and combined. Clients are satisfied, avoiding compromising the technical platform and the product architecture of the different variants. However, the adaptation to production is decisive and production has increased automation, with less flexibility in relation to the products. Still, product development has focused on the engineering view and the development of building components which fit in the predefined or well-established production facility while at the same time satisfy customer demands, i.e., maintaining the balance between distinctiveness and commonality. The study has observed one IHB company and two of their development projects focusing on changes in the product architecture for components across several of their product families. The development has been carried out in a bottom-up fashion. The results indicate difficulties in finding solutions, which fit production. An integrated design of production obstructs product development; the selection of project participants may affect the project results, both in terms of prior experience but also the problem-solving ability; the lack of project documentation is costly since experience is not captured, which could be recycled in future developments.

Abstract [en]

Management innovations are an important source of competitive advantage, but we lack knowledge on the implementation process, not least in small- and medium-sized companies (SMEs). Recognising that psychological ownership (PO) represents a crucial aspect of the implementation process, we address micro-foundational characteristics of the implementation process. PO and critical incident theory (CIT) provide a lens enabling this micro analysis. The empirical setting is the implementation of Hoshin Kanri, a strategic management system in eight small companies. From the analysis of the eight cases, we operationalise four dimensions that characterise how PO evolves in the implementation process: types of PO incidents, frequency of PO incidents, incidents indicating an increase or decrease in PO, and incidents addressing individual or collective PO. Looking at how PO is developed both among CEOs and managers in SMEs, we use the four dimensions to characterise the evolvement of PO within the focal organisations. In doing so, our article elaborates on PO as a driver and, if insufficiently developed, an impediment to effectively implementing management innovations.

Abstract [en]

Purpose

The purpose of this research is to support the customization ability for industrial house building companies striving to offer individualized products but with a strategy which includes a production facility. This is accomplished by analyzing the as-is state in terms of existing engineering assets and by proposing a to-be state using the design platform and product lifecycle management (PLM) support.

Design/methodology/approach

This study is based on design research methodology and collected data are in-depth interviews, document reviews and workshops and method development. The theoretical baseline is product platforms and the design platform.

Findings

The analysis showed that despite use of a platform, inherent assets are disorganized. Still, the identified object-based engineering assets were possible to include in a conceptual proposal for better management, both in the process and product view, using an asset relationship matrix and a PLM system.

Practical implications

The results should be applicable for industrial house building and off-site construction companies and offers an approach to identify and manage their assets and platforms which are crucial to stay competitive.

Originality/value

Previous research on design platforms has focused on engineer-to-order companies within the mechanical industry. The contribution of this paper lies in the application and support of the design platform for industrial house building and the introduction of PLM system support.

Abstract [en]

A vast body of research has described product platforms as strategic enablers for increased business competitiveness, but there is a lack of empirical research describing what types of assets that are used in industry as elements in a platform. Previous research has suggested a platform as a “collection of assets shared by a group of products” and also classified these assets into four transdisciplinary categories: Components, Processes, Knowledge and People and Relationships. This categorization is, however, too imprecise to identify the core assets needed to build a platform, and better guidance is needed. This paper presents a cross-case study of assets used in the product development process at two case companies. These represent two different product disciplines: Industrialized housebuilding, a sector within the construction trade, and Outdoor Power Equipment producing forest and gardening tools. The main contribution of the paper is a comparison of what formal and informal design assets that are used in the two disciplines.

Abstract [en]

Industrialised house building (IHB) design incurs complexities as extensive engineering are required due to high customisation. Companies use different production strategies (PS) to develop building components ranging from standardised to customised depending on the requirements. Platform-based product development has received increased attention from IHB companies striving to be competitive in the industry. However, strategies for platform development supporting the design process are not well-defined for companies using a combination of PS in their development. This study proposes a framework using different PS in the development of a product platform to support the design phase of the post and beam IHB system. Empirical data were gathered from a Swedish multistorey house building company. The main contribution of this study is to provide insights into production strategies while designing components. Moreover, the case is used to exemplify how different subcomponents of the building system can be classified into production strategies and facilitate postponement of strategies to achieve platformbased development. The potential application of different support tools and methods in incremental platform development has been presented.

Abstract [en]

The introduction of product platforms has been acknowledged as a strategic enabler for increased business competitiveness. A vast body of research has described different aspects of platforms, but little work has been done on defining or delimiting the different types of elements that may build up a platform. Design assets include platform elements that are not commonly considered as a part of a platform. Previous research has suggested the introduction of formalized design assets to systematically extend an items-based platform with intangible elements. These are transdisciplinary objects, specifically prepared for reuse between projects to provide support for a wide range of engineering activities: specialized CAD geometry, working methods, spread sheets, function models or different types of knowledge representations, among others. The presented research is part of a larger project seeking to improve the collaboration between product development and manufacturing. This paper focuses on the use of potential and formal design assets at a development department of a global manufacturer of consumer products. The results show that the application of formal design assets depends on several factors, such as the level of professional experience and individual working styles. The contribution of the paper is a description of which formal and informal design assets that are used and a discussion on how the formal assets can be better utilized.

Abstract [en]

Design for manufacturing and assembly (DfMA) has gained increased attention in the construction industry as the process has been industrialized and shifting towards a combination of factory prefabrication and assembly on site. The aim of this study is two-fold. Firstly, to apply the DfMA approach in the redesign of a steel bracket from a post and beam building system to simplify the design for reducing the cost and improving manufacturability. Secondly, to experimentally evaluate the mechanical properties of the redesigned bracket for implementation. An experimental case study has been conducted in a multistorey post and beam building system. The empirical data were collected from five semi-structured interviews and two workshops.

The result shows that the DfMA approach has the potential to improve the manufacturability and cost of building components in Industrialized house building (IHB) and is comparable to lean design. Moreover, the proposed steel bracket offers satisfactory load-bearing capacities and shows an improvement with a reduction of cost by 15%, lead time by 50%, and material efficiency by 25%. DFMA can be used as a promising approach for aligning the design phases of IHB with the production and assembly by improving cross-functional collaboration.

Abstract [en]

By building upon the prior work exploring the nature of practicing and knowing in collaborative research (CR), this article argues that focusing on how trust evolves in collaborative dialogue could enhance the learning potential in CR projects. Drawing from 42 workshops within a CR project, we analyze how dialogue and learning practices develop trust. We use the dialogical framework developed by Walton and Krabbe (1995) to identify and classify 107 dialogues. From our data, we identify three distinct dialogical patterns (educating, inquiring and practicing). These three dialogical patterns are related to four learning practices that are conceptualized as knowledge sharing, knowledge gapping, knowledge bettering and knowledge speculating. Combined, these dialogical patterns and learning practices develop collaborative trust in CR projects. We propose that these results represent an emerging conceptual language that addresses the development of trust in managing CR projects. This conceptual language can both improve managerial practice in the CR context and inspire future theory building.
