Item type:Publication, Access status: without files , Reference products in PGE - Product Generation Engineering: analyzing challenges based on the system hierarchy(Elsevier, 2018-05); ; ; ; PGE - Product Generation Engineering describes that new products are developed based on reference products by three types of variation: carryover variation, embodiment variation and principle variation, where the two latter ones together form the share of new development. Existing approaches relate development risks to the share of new development and the organizational origin of the used reference products. However, several observations suggest that the level of the system structure, which is affected by the new development activities, is also an influencing factor. The contribution at hand aims at a more detailed investigation of this influence. For this purpose a case study is used, covering the first two generations of the dual mass flywheel. Based on this case study an existing approach for the estimation of development risk in PGE is extended to depict the system level, which is subject to new development activities, as an influencing factor. The extended framework is then applied on the development of the system of objectives for a new product generation of an automotive OEM. The framework is capable of displaying the development risks that had been encountered in the development of the first two DMF generations. However, further evaluation using more examples, stays necessary. The framework can serve as a basis for the early derivation of measures which have to be taken as next steps for the handling of identified risks.Publicationtype: Journal Article21 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , A training framework for the synthesis of a consistent system of objectives in modular designModular design (MD) enables a set of methods to reduce development costs. There are extensive scientific findings on MD, but in practice, many companies still find it difficult to harvest the full potential of introducing and sustaining MD. One challenge are the highly interactive objectives of MD and the associated products. These different objectives have to be managed in such a way that a consistent System of Objectives is created. To this end, the various stakeholders can develop a common understanding in their MD processes. Consequently, a framework to support a consistent System of Objectives in MD can support this. In this paper a demand and target group oriented training concept to bridge this gap between theoretical findings and in practice-exploited potential as well as to improve the introduction and sustaining of MD is introduced. An important cross-functional insight is thereby how training concepts for Systems of Objectives in modular development can be designed. With expert interviews different requirements, such as "corporate structure", "dealing with conflicting objectives", "temporal robustness of products against changes", "product configuration", "change management", "product architecture" and "process integration of suppliers" were identified. Based on these findings a three-stage framework was developed to identify the relevant fields of knowledge for each training concept individually. The training is based on a multi-media approach with participative learning and gamification elements. The concept is modular and round-based, so that the difficulty level can be increased in each round, in order to maximize training effects. It focuses on intra-corporate stakeholder management and communication between different disciplines, such as management and engineering.Publicationtype: Journal Article18 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Towards a decision-making framework for multi-criteria product modularization in cooperative environmentsModular product family design is a strong strategy to offer a wide range of product variants economically. Many methods for designing and assessing modular product concepts are provided in literature - deciding between modular product structure alternatives, however, is still a challenging task, because of the many and unforeseeable effects on all product life-phases in combination with the high number of involved stakeholders. In addition, modularity alternatives cause multi-dimensional trade-offs that make the decision process a complex challenge. Current approaches to decide the product modularization tend to focus on the prediction of either internal or external consequences. Furthermore, they rarely consider the prevalent situation of a company’s internal tier structure with different organizational sections, responsible for different module design and supply. In this paper, we investigate modularity decision problems and introduce an innovative framework and modularity decision dashboard, considering internal and external variety evaluation, conflicting objectives of stakeholders as well as company-internal tier structures of component, module and product suppliers. The approach builds on the integrated PKT-approach for developing modular product families, recent findings in complexity cost evaluation, effects of modularization and modularity decision problems. An industrial application at a modularization strategy project in an international powertool company is presented and proves basic validity of the framework and the process model. The results of the study demonstrate how an applicable modularity decision dashboard can facilitate cooperative decision-making and leads to a balanced variety for the electromotor module portfolio in an industrial environment.Publicationtype: Journal ArticleScopus© Citations 8 278 426 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Coping with complex systems-of-systems in the context of PGE – Product Generation EngineeringOne of the main challenges in product development processes nowadays is to consider the megatrend of individualisation and connectivity within products. Companies are increasingly forced to qualify their own products for integration into an existing system of other products - so called System-of-Systems. These products were initially developed independently of each other. Within this system, their own product acts as a sub-system, consisting of sub-systems itself. The main purpose of such interlinked but independent systems is to fulfil a function that cannot be provided by sub-systems on their own. As a consequence, companies have to consider requirements of complex Systems-of-Systems when developing new product generations. The product development process itself is therefore often subject to dynamic changes due to changing requirements and boundary conditions. On a different system level, similar characteristics and challenges can be found in the development of modular kits. In this context the concept of PGE - Product Generation Engineering has been proven to be supportive in addressing these challenges. With this work the authors analyse the challenges of products in a complex System-of-Systems environment considering the entire product lifecycle and evaluate the potential of PGE in handling these challenges. Therefore three case studies with an automotive supplier and a machine tool manufacturer have been conducted. Their aim is to outline how identified aspects of complex Systems-of-Systems are addressed in industrial practice with the support of PGE. It appears that different objectives of the systems involved, as well as being able to operate independently are the main challenges when coping with complex Systems-of-System. It is shown, that PGE is able to support the development process of complex System-of-Systems to a certain extend in a beneficial way.Publicationtype: Journal Article29 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Product Profiles: Modelling customer benefits as a foundation to bring inventions to innovationsm(Elsevier, 2018-05); ; ; ; According to recent studies, early and clearly defined customer's demands and provider's demands are necessary elements for the future success of a product. Product profiles within the scope of ASD - Agile Systems Design describe these demands. As product characterizations in the early development phases, product profiles do not anticipate the technical realization of the product, but rather model customer's benefits and provider's benefits as use cases, requirements and boundary conditions and thus include value-added product attributes. By this, product profiles represent the interdisciplinary design objective and form the core of the related generation of business models. However, there is a lack of a suitable methodology to systematize the generation of product profiles. There are no approaches that allow the consideration of corresponding reference products in the context of PGE - Product Generation Engineering when generating product profiles. Starting with a retrospective study, more than 100 product profiles and their development in three Live-Labs with industrial participation as well as three industrial innovation projects are analyzed. Based on this a definition of product profiles is derived and a product profile scheme to model profiles is introduced. Furthermore, the different modules as elements of product profiles are explained.Publicationtype: Journal Article29
