Evaluation Of Configuration Design For Complex Products

The core of mass customization is to provide customers with diversified products, as well as to reduce the internal diversification of the enterprise in order to reduce product cost and improve product quality. Reusing resources is a main method to reduce the diversity. To configure a complex product, a proper evaluation method of the selection of modules and parts is necessary, besides it need an evaluation method of the final configuration scheme. In order to meet the core of mass customization, it is necessary to make a systematic evaluation of configuration schemes from product lifecycle standpoint. In this paper, evaluation methodology of configuration design cases for complicated product was studied deeply on the case library of product with the theory and method of complex network. Universality and integrativity evaluation of the module in product platform, and evaluation method of final configuration schemes are proposed. As an example, the methods are applied to industrial steam turbine and are verified. The main research contents in this paper are as follows:Firstly, the configuration design principle and methods of mass customization, the current situation of the research are expatiated. The significance and main content of paper are given. As a result of having regard to the product lifecycle, the building process of product platform is elaborated from the angles of parts master model and product family primary structure. And the process of configuration design based on product platform is described.Secondly, the method of building product family modules affiliation network based on parts case library is researched. Based on the complex network, parameters such as re-use number of module and modules related degree are calculated through a search algorithm of simple path. Through the analysis of the parameters, the evaluation methods of universality and integrativity are proposed separately.Finally, the method of building product family parts affiliation network is researched. The characteristics of the network are analyzed, combining the degree distribution rule, the evolving rule and dynamic equation of component relation network based on the factor of the average out-degree have an effect on the in-degree distribution are proposed. Based on the parts relation network, parameters such as re-use number of part and parts related coefficient are calculated through a search algorithm of simple path. In addition, combining clustering coefficient, the evaluation method of configuration design schemes for complex product is presented.
