Research On Product Configuration Design Method Based On Fuzzy Optimum Selection

Mass customization is considered one of the 21^st century main production models, which combining with the advantages of customization production and mass production. It not only can satisfy the customer's individual requirement, but also can keep lower production cost and shorter due data. Design for mass customization is a method to realize mass customization production. As one of the key technologies of design for mass customization, product configuration design can rapidly configure the personalized product that satisfies the customers' requirements. And the reasonable organization and expression of the production resources is a foundation to realize product rapid configuration design, so the research on production resources organization and expression, product configuration is very important. Currently, scholars all over the world have devoted to research on product configuration design method for mass customization. Based on summarizing the correlative literatures and analyzing the problems in current research systematically, the classification, expression method and organization process of the production resource is given, and the rapid configuration design model based on the fuzzy optimum selection is also given. The method using rough set theory to obtain the attribute weights of the key features in measuring the similar instance. Finally, the prototype system of the product platform of ZhongQing crane is developed.The contents of the dissertation are summarized as follows:Chapter one is introduction. The information of mass customization and product configuration design is summarized, such as the basic concept and advantage, and so on. Based on the current situation of the product configuration design, its problem is analyzed deeply, and then the research content and architecture of this article is brought forward.Chapter two introduces the basic theory of product configuration, presents the product configuration method oriented product family and build the basic model of fuzzy optimum selection.Chapter three studies the classification; expression method and organization process of the production resource and emphatically introduces the product parts and components resources. And all module's structure and function of parametric finite element analysis resources, also the key technology.Chapter four studies the key technology of realizing product rapid configuration, presents the method which gets the similar instance through fuzzy optimum selection in the product configuration and introduces the method based on rough set theory how to measure the key features attribute weights. As an example of crane, the process of rapid configuration is discussed.Chapter five is related to the science and technology hall of Zhejiang province's project "Research on the rapid response integrated design platform based on the product family and modular planning", the product platform of ZhongQing crane is developed, proving the feasibility of research method.The last chapter is conclusion and outlook. The achievements of the dissertation are summarized, and the innovations are pointed. The future works are put forward.
