Research On MC-Oriented Modular Planning For Complex Product

With the continuous development of the diversification and individuation of consumer demands,differentiated products have been becoming a business goal instead of the single mass productionproducts. In order to adapt to this competitive market environment, the business competition hasbeen focused on how best to meet the individual needs of customers, that is, to make the individualproducts which meet the customer demands as far as possible without increasing product cost anddevelopment cycle. Mass Customization (MC) provides a way to solve this problem. Masscustomization is a new mode of production which is trying to make products to meet the customerindividual demands with the speed and cost of mass production. One of the key factors of thisproduction mode is how to divide the complex product modules effectively.The complex product module planning theory and realization technology for the masscustomization are studied deeply based on the support of these projects including the national keyresearch project:"The key technology research and application of manufacturing information(Hefei)"(2001BA201A56), the national technology and industry commission project:"Development of common part intelligent design system based on multi-CAD platform "(2005BA201A3-01), the Anhui science and technology research project:"Establishing product datamanagement platform based on Web"(40120513) and the Hefei key research project:"Research onthree-dimensional CAD/CAE integrated design method of hydraulic machine "(2007(1007)).Firstly, the complex product module partition need is analyzed as well as the concept of thecomplex product module partition for mass customization after summarizing the concept of masscustomization. The theoretical system of complex product module partition for mass customizationis summarized and analyzed from the system point of view. Starting from the qualitative analysis ofmodularization formation mechanism, the formation mechanism of complex product modularizationbased on the design axioms is proposed. According to the axiomatic design idea, the formationmechanism and expression mode of the ideal design matrix product modularization are analyzeddeeply. In order to reduce the complexity of module partition, the modular pre-partition methodderiving from the engineering experience is proposed. The product pre-partition method is tested byan example of YH30hydraulic machine.Then, based on the analysis of previous studies, a mathematical model of function modulepartition is established according to the contribution matrix of product components and functionmodules. A particular algorithm based on hybrid PSO is designed for the above model, which canovercome the shortcomings that genetic algorithm and PSO are prone to premature, and simulatedannealing algorithm has poor converging capacity. Finally, the computational results are given to prove the feasibility and effectiveness of this algorithm. Aiming at the lack of the reasonableevaluation of the modules after the module partition program formation, a two-tier module creationprogram evaluation method is proposed with the D-S evidence theory. The comprehensiveevaluation of module creation program satisfaction is conducted from the aspects of uncertainty andincompleteness with six indicators, including assembly complexity, manufacturability,interchangeability, stability, configuration results and compact volume. This method is consistentwith the judging process of human thinking, and has a certain degree of flexibility, efficiency andrationality.Finally, on the basis of the research of the complex product module partition theory architectureand key technologies for mass customization, the system architecture of the overall framework isestablished. By briefly discussing the major functional modules of the system and giving someinterfaces of the system prototype, the features of module product design and development areperformed, such as the integration, collaboration, networking and knowledge-based, and the validityand feasibility of this theory is also proved.
