Item type:Publication, Access status: without files , Cost based design of modular product families using the example of test rigs(2017-08); ; Companies with a wide range of variety on the markets have to reduce their internal variety for reducing their costs. This can be reached through modular product families, where more than one concept is possible. A decision making based on costs is missing for the choice of the developed concepts. In this Paper an approach for developing modular product structure concepts based on cost is presented. Based on literature review the Integrated PKT-Approach for developing modular product families is adapted for analyze cost, process and product structure for developing and cost prognosis of concepts and modified tools for analyzing cost are explained. This approach is used in a case study for an industry company where three cost-efficient variety optimized concepts were developed. The approach is helpful for developing cost-reduced concepts based on cost analyses and gives a cost prognosis for rating the concepts.Publicationtype: Conference Paper82 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Cost effects of modular product family structures: Methods and quantification of impacts to support decision making(2017-01-06); Customer demands and global markets prompt companies to offer increasing product variety. The use of modular product structures is a possible strategy for providing the necessary external variety to the market and reducing costs by lowering internal variety within the company. Current research provides several approaches for developing modular product family structures. As modularity is a gradual property, these methods generate different product structure concepts and companies have to decide at an early stage and without detailed information which concepts to implement. Most existing modularization methods offer only little or no support for decision making, particularly in terms of cost effects. This article illustrates the cost effects of variety and modular product family structures, the various cost impacts of variety management strategies and modularization methods in a literature review. A new approach to quantify these cost effects to support concept selection during modular product family design is introduced.Publicationtype: Journal Article190 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Global Views on Modular Design Research: Linking Alternative Methods to Support Modular Product Family Concept Development(2016-07-01); ; ; ; Modular product platforms have been shown to provide substantial cost and time savings while still allowing companies to offer a variety of products. As a result, a multitude of product platform methods have been developed over the last decade within the design research community. However, comparison and integration of suitable methods is difficult since the methods have, for the most part, been developed in isolation from one another. In reviewing the literature in modularity and product platforms, we create a generic set of 13 platform design steps for developing a platform concept. We then examine a set of product platform concept development processes used at several different companies, and from this form a generic sequence of the steps. We then associate the various developed methods to the sequence, thereby enabling the chaining together of the various modular and platform design methods developed by the community.Publicationtype: Journal Article130 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Cost prognosis of modular product structure concepts(2015-07); Modular product structures are often used by companies dealing with a high variety in their product families to cope with that challenge. Due to the gradual properties of modularity, more than one modular product structure concept is developed. The cost prognosis shown in this paper supports the selection of concepts by making the monetary effects of changing product structures transparent. It is one unit of the complexity cost management approach, which is based on a systematic literature review. The correlation of the method unit with the integrated PKT-approach is shown and compared to methods from literature. The cost prognosis is described in detail using the example of a product family of floor cleaning robots and verified by applying it on a product family of elevators. The detailed analysis of cost effects of modular product structure concepts supports decision making and leads to cost advantage solutions.Publicationtype: Conference Paper38 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Platform concept development within the integrated PKT-Approach(2015-07); ; The development of modular product structures and platforms for product families is used more and more in companies to cope with the increasing complexity. Both approaches, modules and platforms, contain the definition of a certain degree of reusable elements which leads to a reduction of the internal variety, e.g. a reduced number of parts. The integrated PKT-approach is a method toolkit including different combinable method units supporting the development of modular product structures with reduced internal variety. The aim of this paper is to include the specific development of product platform concepts and the evaluation of different concepts regarding complexity costs into the integrated PKT-approach on an exemplary product family.Publicationtype: Conference Paper50 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , An assessment of methodical approaches to support the development of modular product familiesGlobal competition and the trend to individualized products force companies to lower their internal variety, which can be achieved through modular product structures. The literature comprises a wide range of approaches to support the development of modular product families. A selection of significant methods are investigated and evaluated. The method Integrated PKT-Approach for Developing Modular Product Families developed at the Institute of Product Development and Mechanical Engineering Design (PKT) is also characterized. This approach was developed based on the existing literature and approaches and further experience from industrial practice. It integrates aspects of design for variety with technical-functional and product-strategic modularization methods. The methodical approach, as well as its relevance and development, is explained in addition to the literature review. © 2013 The Design Society, unless otherwise stated.Publicationtype: Conference Paper53 - 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 Paper71 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Komplexitätskosteneffekte modularer Produktfamilien [Complexity cost effects of modular product families]The development of modular product families provides a way to reduce the total products cost. Costs forecasts in the early stages of product development support the development and selection of modular product structure concepts. In this paper a case study for predicting the costs of harness variants is shown. Next, according to the results of the case study, an approach for costs forecast by the identification and determination of the effects of complexity costs elements is presented. This approach represents an extension of the Integrated PKT-Approach for the development of modular product families.Publicationtype: Conference Paper49 - Some of the metrics are blocked by yourconsent settings
