Item type:Publication, Access status: with files , Methodische Unterstützung der Entwicklung von Produktprogrammen mit hoher KommunalitätMegatrends of globalisation and individualisation characterize global markets. Hence, varying individual customer needs need to be satisfied and products need to be compli-ant with country-specific conditions while maintaining marketable prices. Offering a broad variety of products cost-efficiently, becomes a crucial success-factor. Yet, a broad variety of products leads to more complexity, causing more costs. These complexity costs incur for instance because of higher storage expenses, excessive logistics and smaller lot sizes. By developing modular product families, product variants can be con-figured from a small number of modules in order to reduce complexity. The modular design enables the use of common components in several product variants, so called commonality. In recent decades, several approaches have been developed to increase the commonality of product families, among others the Integrated PKT-Approach for Developing Modular Product Families. Still, additional potential can be exploited by using common modules even across product families. As there are no sufficient meth-ods for a product program wide approach yet, the aim of this contribution is to develop methodical support for the development of common product programs. This method includes the Carryover Chart (CoC), a newly developed visualisation of product programs regarding their carryover modules. At first potential carryover candi-dates are identified using the CoC. Analysing this potential as well as the actual needs for more commonality or more differentiation, a product program specific product structure strategy is developed. In accordance with this strategy the carryover candi-dates are developed as modules with common use across product families. This phase includes design for variety in order to achieve higher component commonality. The effect of higher component and module commonality on the product life phases is evaluated and optimized. These steps are supported by partly existing and adapted method units of the Integrated PKT-Approach. Resulting concepts are compared in a newly developed breakeven analysis in order to understand the effect on production and complexity cost. Applying the method on a product program of fork lift trucks and the design of base frames it is successfully evaluated. The Integrated PKT-Approach for Developing Modular Product families is extended by the new method to the Integrated PKT-Approach for Developing Modular Product Programs.Publicationtype: Doctoral Thesis2158 1517 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Early phase estimation of variety induced complexity cost effects: a study on industrial cases in Germany(Springer, 2016-08-17); ; ; ; Offering a broad external market variety at competitive prices is one of the main challenges in the global competition among mechanical engineering branches. Reducing variety and thus variety induced complexity cost has evolved to become one of the crucial global success factors. The aim of this study is to get insights on variety induced complexity cost effects and to elaborate on how these effects can be influenced by modular product development. Firstly, general causes and effects of variety are described portraying their trans-disciplinary nature. Next, the state of the art in reducing variety by modular product development is explained. Hypotheses on cost effects of variety induced complexity are introduced; and industrial cases from Germany are evaluated in order to support the hypotheses. During these empirical case studies, an integrated approach for developing modular product families by including various corporate disciplines is applied. This trans-disciplinary procedure aims to reduce variety over the whole product life by modularization. The results obtained and their potential effects on complexity cost are presented and discussed. Based on the analysis of these cases, an approach for Early Phase Estimation of Complexity Cost (EPECC) is developed. This approach helps assess trans-disciplinary complexity cost effects of different modular concept alternatives in early design phases. Furthermore, the effect of branch specific lot sizes on complexity cost is illustrated. Factors related to the successful use of these effects in branches and segments with high and low lot sizes are shared from industrial and consultancy practices. This contribution is authored by a team of academicians, consultants, and industrial executives.Publicationtype: Book Part106 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Product life-oriented development of component commonality and varietyTo reach many customers and have a broad range of products at marketable prices companies aim for high commonality across product variants. Commonality is known as the sharing of components by product variants. But using the same components for different product variants can also lead to trade-offs in product function and fulfillment of customer requirements as well as in internal processes. The aim of this paper is to investigate by literature review and a case study on forklift trucks how benefits and trade-offs can be balanced according to corporate needs. Existing tools from the Integrated PKT-Approach for Developing Modular Product Families are applied and advanced in the case study. Practical examples demonstrate that commonality is a gradual property that can be given to variant components as well and that it is influenced by the modular structure and how components are handled as modules in different life phases. New product concepts with enhanced commonality are derived and evaluated by estimating the created lot size caused and code number caused costs.Publicationtype: Conference Paper91 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Towards the development of commonal product programsToday many companies encounter the challenge of reducing internal variety by developing modular product families. Yet even more potential for reducing internal variety can be gained by even striving for carry-over across product families as industrial case studies showed. A holistic corporate product program strategy for reducing variety supports the identification and exploitation of this potential. How this strategy can be defined in specific corporate context is outlined in this paper. Based from the attributes of an ideal product program steps for definition of product structure strategies are proposed. The resulting development tasks need a deep understanding about a solution that suits corporate needs for differentiation and standardization best. This can be gained by analysis of tearing forces towards differentiation and standardization and comparison of possible solutions that enable commonality in different ways and by this have different effects. To support evaluation of these solutions a complexity cost estimation method is proposed complying with the lack of detailed information in the conceptual phase.Publicationtype: Conference Paper70 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , Notwendigkeit für eine Methodenplattform zur Entwicklung von Produkten für nutzerspezifische Mobilitätsbedürfnisse [Need for a platform of methods for the development of products for user-specific mobility requirements](Tutech Innovation GmbH, 2011); ; ; ; A basic need for every human being is mobility. Mobility is far more than the pure ability to move around. In fact it also comprises any kind of interaction with the environment especially the communication with other persons. Since a lack of mobility usually has a tremendous effect on the quality of live technical products that train, assist or compensate the users' mobility, will have a growing importance especially against the background of an aging society. As the need for mobility is highly user-specific, the designer of such products is confronted with a huge variety of requirements through to tailored products. This paper outlines the need for a platform of methods to handle these challenges.Publicationtype: Conference Paper20 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , Modulare Strukturen methodisch in Unternehmen umsetzen - Entwicklung von Standardumfängen und Integration von Erfahrungswissen [Methodically implementing modular structures in the company : development of standard scopes and integration of practical knowledge]The integrated PKT-approach for developing modular product families aims at the methodical development of maximum external product variety using the lowest possible internal process and component variety. This contribution proposes two approaches how to establish modular structures derived by using the PKT-approach within a company in order to capitalize from the benefits modular structures offer. The first approach deals with the methodical development of standardized hardware for use throughout the corporate product program in order to gain lot size effects. How to make use of the expected benefits of modular structures in all product life phases by using knowledge management tools is topic of the second proposed approach.Publicationtype: Conference Paper21
