AbstractDue to the falling costs of computational resources and the increasing potential of data acquisition, interest in digital twins, a virtual copy of the physical original, and their industrial application is increasing. Nevertheless, there is limited published work on how to support the process of physical to virtual twinning and what its key aspects are. The aim of this study is to present insights with regards to physical to virtual twinning gained from modelling projects in mechatronic product development. We conducted a survey and in-depth interviews with members of modelling projects. In the surveys and interviews we identified how physical products and virtual models were linked, which virtual models were used and which general challenges and key aspects are considered important by the project members. Our findings show that the key characteristics that pose challenges to modelling regarding physical to virtual twinning are model granularity, model validation, and model integration and interconnectivity.

AbstractThe success of complex product development projects strongly depends on the clear definition of target factors that allow a reliable statement about the fulfilment of the product requirements. In the context of tolerancing and robust design, Key Characteristics (KCs) have been established for this purpose and form the basis for all downstream activities. In order to integrate the activities related to the KC definition into product development as early as possible, the often vaguely formulated requirements must be translated into quantifiable KCs. However, this is primarily a manual process, so the results strongly depend on the experience of the design engineer.In order to overcome this problem, a novel computer-aided approach is presented, which automatically derives associated functions and KCs already during the definition of product requirements. The approach uses natural language processing and formalized design knowledge to extract and provide implicit information from the requirements. This leads to a clear definition of the requirements and KCs and thus creates a founded basis for robustness evaluation at the beginning of the concept design stage. The approach is exemplarily applied to a window lifter.

There are few studies that have found an adequate means of assessing firms based on their specific needs for a concurrent engineering (CE) approach. Managers interested in introducing CE have little choice but to rely on their past experiences of introducing change. Using data gleaned from a nine month case study, a British-wide survey and a series of in-depth interviews, this paper summarizes the findings of a research study that examines how firms orientate themselves towards change and how they go about introducing CE to their operations. The data show that there are many benefits to introducing CE and that firms differ with respect to their needs for the CE approach. A tentative means to assess CE ‘needs’ is proposed which is based on the level of complexity of goods produced by firms. The method is currently being developed and extended to provide an applications-based framework to assist firms to improve their new product development performance.

Abstract Corporations are spending significant resources to reduce the effect of manufacturing variation on product quality as well as adopt lower cost manufacturing and assembly technologies to reduce the end costs in product development. However, to ensure that these investments have a positive return, efforts must be made to put resources into those areas where there will be the largest return. This paper describes a formalized method to make these decisions. The analysis focuses the tradeoff studies on the Key Characteristics (KCs) of the product. KCs, in use in a variety of industries, are the product features that are most sensitive to existing manufacturing and process variation and will affect the end quality of the product. Two examples from the aircraft manufacturing environment are used describe the application of the proposed methods.

O presente artigo pretende investigar de que forma as mudanças no comportamento do mercado e o crescimento da consciência ambiental tem feito com que os consumidores mudem sua postura e exijam das empresas uma readequação de processos com vistas a adotar métodos de gestão mais alinhados com a questão da sustentabilidade e principalmente dos impactos ambientais de suas ações. Sendo assim, o principal objetivo deste artigo é compreender de que maneira empresas de diferentes segmentos estão implementando os conceitos e ferramentas de ecodesign em seus processos de desenvolvimento de produto. Para tanto, foi realizado um levantamento teórico em periódicos da área, além de um estudo exploratório de campo baseado em entrevistas em profundidade, que mostrou que a motivação das empresas para a adoção de práticas de ecodesign ainda é limitada a cumprir exigências legais, ou como forma de redução de custos. Sob uma perspectiva mercadológica percebe-se que o marketing exerce pouca influência na relação entre o ecodesign e o processo de desenvolvimento de produtos.   This article intends to investigate how changes in market behavior and the growth of environmental awareness have made consumers to change their posture and demand from companies a process readjustment with a view to adopt management methods more in line with sustainability and especially the environmental impacts. Therefore, the main objective of this article is to understand how companies from different segments are implementing ecodesign concepts and tools in their product development processes. For that, a theoretical survey was carried out, as well as an exploratory field study based on in-depth interviews, which showed that the motivation of companies for the adoption of ecodesign practices is still limited to complying legal requirements, or as way of reducing costs.  From a marketing perspective, it is perceived that marketing has little influence on the relationship between ecodesign and product development process.

Abstract Organizing manufacturing in dynamic networks instead of inflexible production lines is one of the key aspects of Industry 4.0. This should serve to realize automation and effectiveness to a higher degree than previously achievable. For this modernization, Cyber-Physical Systems should be utilized, where a Digital Twin mirrors the behavior of its Physical Twin and makes the data during manufacturing externally available via communication interfaces. This Digital Twin should be an instantiation of a Digital Master, which must meet the requirements for communication in dynamically changing value-added networks. The networking capability of objects requires semantic information. This information is associated with rules for decision making within a value-added network. This paper addresses the need for research on how to add networking capabilities during the development of Digital Masters. With these added capabilities, the communication between Digital Masters and Twins in terms of a single part manufacturing simulation should be verifiable in a Digital Factory. For this purpose, the concept of this paper aims to outline guidelines on how to add networking capabilities to the single part, machines and other resources needed during manufacturing.

Purpose Starting from the challenges and implications of doing organizational ethnography within the organization which the researcher is also employed by, the purpose of this paper is to reflect upon the idea of “passing the test” in relation to such ethnographic endeavor. The paper discusses how “collaboration” on projects and in product development processes with colleagues/informants is a precondition for passing “tests,” which unfolded as subtle, verbalized demands made by colleagues/informants during fieldwork. Design/methodology/approach Longitudinal anthropological fieldwork was carried out as part of an industrial PhD project, which investigates digitization as organizational, professional and social practices in the Danish construction industry. The fieldwork lasted on/off from April 2017 to December 2018. Various forms of participant observation and collaborative ethnographic methods were used during fieldwork. Findings The paper investigates how these “tests” focused on two key aspects: the relevance of anthropology in a profit-oriented, technical corporate organization; and the application of anthropological theories and ethnographic methodologies for the benefit of product development, usability studies and organizational change. It is argued that the tests were passed through collaborative engagements, where the author oscillated between positions as collegial insider and outside researcher for the dual benefit of both commercial interests and research interests. Originality/value The paper suggests that daring to collaborate and co-create products (as something different than texts) during organizational fieldwork for the benefit of both corporate and ethnographic interests offers strong possibilities for keeping ethnography relevant and applicable, passing tests in organizational settings and advancing ethnography’s impact in the world.

Society’s transition towards sustainability comes with radical change, which entails significant threats and opportunities for product development and manufacturing companies, for example related to new legislation, shifting customer preferences, and increasing raw material prices. Smart risk management therefore plays a key role for successfully maneuvering society’s sustainability transition. However, from a company perspective, it remains challenging to connect the macro-level societal change with tangible risks for the business on the micro level. Based on interviews with academic and industrial experts, this study identified 21 key aspects for sustainability risk management. Drawing on these results and research from the areas of transition design, strategic sustainable development, and sustainability risk management, a conceptual approach for strategic risk management within the sustainability transition is presented. It builds on layered, double-flow scenario modelling in which backcasting from a vision, framed by basic principles for sustainability, is combined with forecasting from the present. The implications of such scenarios, i.e., risks, can then be identified and managed. By doing so on different scales, connections between macro- and micro-level change can be established. Thereby, product development companies shall be supported in making sustainability an intrinsic part of decision-making across the strategic, tactical, and operational levels to increase competitiveness while contributing to the transition towards a sustainable society.

Operating as a commercial business with public functions, Weibo’s pursuit of profits has to be balanced with the demands of citizen users. This article examines how the dynamics between increasing profits and preserving public interest manifests itself in Weibo’s monetization and how the dynamics impacts Weibo’s public functions. Drawn on evidence collected through participant observation and 19 in-depth interviews, this article first provides a description of the major practices of monetization. Next, it describes how the introduction of commercial elements, the cluttered product development, and the embrace with strong domestic capitals reshape Weibo’s public functions. Finally, it concludes with a discussion on the attitude of Weibo toward the dynamics between profits and public interest, and how Weibo’s pursuit of profits under the market influence has to be included when examining Weibo’s impact on the development of Chinese society.
