Model Based Definition (MBD) is a new strategy of PLM based on CAD models transition from simple gatherers of geometrical data to comprehensive sources of information for the overall product life cycle. With MBD most of the data related to a product is structured inside native CAD models, instead of being scattered in different forms through the PLM database. MBD aims are suppression of redundant documents and drawings, better data consistency, better product/process virtualization, better support for all CAx tasks under Engineering and Manufacturing disciplines. Developing MBD today, for a medium-large size company in the automotive and aerospace sectors, deals primarily with its fundamentals: data structures. Companies need a common approach to structure data in reusable, unified forms inside native 3D CAD models. For this reason this research work has been by developed focusing the attention on a method for supporting the MBD implementation by the use of the QFD approach. In order to analyze the efficacy of the proposed approach, it has been validated in the aerospace and defense domain where companies deal with complex products, characterized by a large amount of data exchange, and where collaborative design is a fundamental practice.
Supporting product development in the textile industry through the use of a product lifecycle management approach: a preliminary set of guidelines springer Publisher:
Requirement management represents one of the key process in the complex product life cycle because it is involved not only at the beginning, but also in the further phases where the definition of the technical specificationssometimes implicates requirements tradeoff due to conflicts. For this reason the role of RM tools and methodologies, that normally represents a stand-alone solution, has to change and to be more integrated in the Product Lifecycle Management platform.At present a real shared integrated RM solution doesn't exist and for this reason it is necessary to provide a framework for supporting the customization of the available RM solutions for catching the real and specific company needs in this new collaborative scenario.For this reason this paper presents a methodical approach that incorporates user-centered design principles into the customization process of the tool. It permits to be adopted in each possible company scenario thanks to its ability to catch the company specific needs and further identifying the right features for the company. The proposed methodology puts the user, rather than the system, at the center of the process because the RM solution could be considered effective only if it is able to save time and money in the data management by users. Moreover, this tool assessment method can help organizations efficiently determine candidate tools, to understand what is important in that organization and to make a tool selection customized for their needs. The case study on Requirement Management tools as Part of Product Lifecycle Management (PLM)Solution is presented.
