Item type:Publication, Access status: without files , Impact of Modularity Decisions on a Firm's Economic Objectives(2020-04-01); ; ; ; Research in modularization of product families reveals numerous individual cause and effect impacts of modularity on the firm. While many modularization methods are present in the literature, an overall combined picture of the interrelations of modular product structures on the firm is yet missing. This makes the construction of an economic business case for modularity difficult. The aim of this work is to show a causal network of how modular product structures affect a firm's economics through modularity's impact on the firm's activities over its products lifecycle phases. Therefore we introduce a literature based impact model on the basis of three main cause and effect node types, being (1) modularity property causes leading to (2) product life phase effects, leading to (3) economic impacts. We show how modularization decisions on a product family structure can impact activities in the product life cycle differently and the resultant economic outcomes. The cause and effect model is a combined summary of the corpus of knowledge found in the literature, highlighting for example that modularity can have an initial negative delaying effect on the development time for a platform followed by a positive reduction in product variant development times, and can a positive impact on reduced manufacturing costs. For validation the model was evaluated by industrial experts against nine case studies of major product-family-wide design projects, marking effects that were experienced and observed in their modularization projects.Publicationtype: Journal Article423 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Towards an impact model of modular product structures(2017-08); Modularization of product families affects firms in many ways. Many of them have been investigated in research and observed in industry. But which effect will most likely occur, by which kind of modular product structure it can be achieved and how this product structure affects other life phases is often not clear because the understanding for the whole system of product structures and effects is missing. The aim of this paper is to show the interrelations between product structures and the effects they entail. Hence it provides the desired system view. For the model development the properties and characteristics are defined to be able to differentiate product family structures. For collection of the effects a literature study was undertaken, the effects and their product structural causes are investigated and displayed in a flow chart based visualization, which is divided into product life phases. The value of the paper lies in the provision of a visual model including product structural cause and its life phase effects on a firm which has been missing in literature and is important for decision-making.Publicationtype: Conference Paper92 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Assessing impacts of modular product architectures on the firm: a case studyProduct modularization is difficult and has far-reaching impacts for the company. It requires a sound understanding of cause and effect chains, which start with product structure decisions, such as module boundary definitions or interface specifications, and lead to essential target values consisting of cost, quality and time categories for each product and the product portfolio. This paper investigates effects of modularity on product development and the challenges to assess them, and gives a further hint research on support for decision makers in the context of modular product definition.Publicationtype: Conference Paper60 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Effects of modular product structures on life phases and economic factorsThis paper contributes to the lack of an overall understanding of the impact modular product structures have on economic factors. Therefore a literature study is conducted in this paper and an impact model is created, providing cause-effect chains between modularity and economic factors. Effects which have been observed in product life phases are named and if possible related to their cause, being one of the properties of modularity (commonality, seperability, combinability). The life phase effects are then summed up to general strategic and economic factors.Publicationtype: Conference Paper86 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Multi-domain modeling with graph databasesThis paper presents the use of graph databases in multi-domain modeling. Computational tools have been developed to model and analyze complex systems by querying system model elements and their relations across domains. Graph-based thinking is established as a tool in the research field of complexity management and product family design. The recent availability of general-purpose graph databases makes it possible to unify system model thinking and data storage. This paper connects graph databases with system modeling of multiple domains and presents an example of a product family structure. Data storage types as well as strengths and weaknesses of using graph databases in system modeling are presented.Publicationtype: Conference Paper37
