System Modeling And Supporting Software Development Of Product Collaborative Development Chain Base On Product Platform And Axiomatic Theory

With intensive global competition, various requirements and the limitations of single enterprise own resource and development capacity, the firms need to increase the content and frequency of external-cooperation activity, suppliers play more important roles in new product development (NPD) . Optimizing, integrating and utilizing the various resources in-and-out the enterprises has become the key factors of NPD. System management and optimum allocation of design information and resource across enterprises has become the core of competition. PCDC (product collaborative development chains) provides an effective platform and method for this new development pattern.First, the definition of the PCDC is presented, and the characteristics, requirements of PCDC are analyzed. Then a three-dimensional model of PCDC, including technology view, life-cycle and application module dimensions, is proposed, the mapping method of the PCDC based on requirement domain, technology domain and resource domain is described. System modeling provide a support and guiding framework on reducing product development time and cost, and improving access to and application of new technology and the satisfaction degree of customized requirements and innovation of product.The construction of product platform of inter-enterprise and resource optimization is not only the core for the implementation of PCDC, but also the foundation and key factors of product innovation and rapid development. The currency and configuration of the product family were decided by the size and restriction identify of the granularity of platform. With the increase of component outsourcing in new product development, its impact on product modularity should be analyzed: one is the design related factor such as product function and structure, the other is the manufacture related factor such as component suppliers. Based on the consideration of design and manufacture related resource factor, an interactive modularity planning model using fuzzy clustering identification is proposed and an evaluation algorithm is given to select the optimal module family and then product platform is constructed based on module anasys matrix. According to the above analysis and research, based on the investigation and research on the status and characteristic of the China machine manufacturing, the case for construction of product platform of inter-enterprise were given.It has been found that selecting proper participator to involve effectively in product development process at right time and to right extent is vital to the success of product collaborative development, and the characteristics of product structure and the catalog of resource and suppliers and their relationship was precondition and base of deciding the time and degree of the supplier involvement. By analyzing of the characteristics of suppliers involvement in product collaborative development, the definition of the degree of the product innovation, components and involving suppliers was proposed. And then a mapping method and algorithm for parts and involving supplier definition was discussed. Based on the materiel supply chain and new product development, the indices development which includes satisfaction, flexibility, venture and confidence index for measuring the extent to which both the customers' requirements and supplier capabilities match or mismatch was presented. And then the supplier's evaluation process and the algorithm were proposed. And then an example of supplier selection in NPD is discussed.Finally, according to the characteristics of PCDC and Axiomatic Design, based on ASP, SQL Server, the software prototype of the integrated management system with a three-tier structure of the reference model was proposed, which provide an unified, coordinated teamwork platform for the effective development and deployment of the distributed resources. The design and implement of PCDC integration management also offer a powerful and flexible platform for technology supporting on the satisfaction degree of customized requirements and innovation of product, and a tool for system ansysis and decision-making.
