Research On Key Technologies Of Modular Product Platform Based On Network Analysis Method

With the formation of world market, the competition between enterprises has focused on how to deal with the conflict between scale economies with batch production and customers'individual requirements in Mass Customization. An effective method is product family development and design based on product platform.Nowadays, it has been becoming a research hotspot in systems science to study the evolving dynamics and network features of complex systems based on network analysis method and the theory of complex networks. The theory of complex networks which originated from the combination of graph theory and probability statistics studies dynamics systems controlled by all kinds of mechanisms in the world. Up to now, there have been few contributions on application of network analysis method in mechanical products area.This paper researches on network models of real mechanical product system based on the theory of complex network and network analysis method. In order to build modular product platform, measurement method of modular s commonality and how to build main structure of product family is proposed via analyzing topology characters and evolving rules about product family's structure network. The main research work of the full paper is as the followings.Chapter 1 gives the review of product platform and network science and theory. The requirements of research and the shortage of present research are analyzed. Then the research content and architecture of the dissertation is presented.Chapter 2 introduces the concept, variety and design methods of product platform firstly; Second, the theory architecture of modular product platform is presented; Third, the process and key technologies of modular product platform development is summarized.Chapter 3 focus on network science and network analysis method, including the steps of network analysis method, network statistical parameters, network characters and topology, evolving models of network, and so on.Chapter 4 studies the construct method, topology character and evolving process of two network models of product family structure, which is the basis of building main structure and modular product platform. As an example, the methods are applied to industrial steam turbine.Chapter 5 analyses the elements and characters of modular product platform and studies the commonality index of generic parts based on network model. The method of classifying modules has been researched also. Expatiating on how to build main structure of product family is given particularly.Chapter 6 puts forward layered construct model of modular product platform and analysis different evolving instances of modules in platform. This chapter also research the dynamic optimize process of modular product platform.Chapter 7 summarizes the dissertation and prospects the future research work.
