[Abstract]:As a new concept derived from technological systems, complex product system (Complex Products and Systems) in engineering equipment, aerospace and other strategic areas of priority to the development of Chinas, plays an irreplaceable important role. With the progress of science and technology evolution and the subsystem of accelerating the complex product system, emerging customer needs continuous emergence of continuously changing existing customer demand, the objective requirements of complex product systems need to continuously improve the development efficiency, to deal with the complex and changeable market environment. The existing complex product system research mainly focus on the conception and characteristics of interpretation, research and explore the innovation mechanism of operation management and complex product system related factors on new development in several variants of the product, the lack of basis, through the study of design knowledge reuse and modify the retrofit design to improve the efficiency of research and development of the module. The design is widely used in the field of mass customization, the product structure, the effective methods of standardized design variables in order to improve the efficiency of product development. Compared with the traditional mass customization, complex product system is highly complex (including complex function, subsystem components / large number etc.) and significant heterogeneity (including function. The principle, structure and heterogeneity) characteristics, and the traditional modularization method in design theory is difficult to effectively deal with these features. In order to improve the existing system of complex product structure and function of the degree of standardization is the cause of construction of complex product system of modular product structure and value planning module parameters summed up two scientific problems around, study complex product system modules, module division and module planning scheme evaluation parameters of three key technologies, to build complex product and system parameter The module structure, promote the structure of complex product system structure evolution from the integrated structure to improve the knowledge module, the modified design of complex product system design in the reuse and modification efficiency. The main research contents include the following: (1) the concept of complex product system explains the characteristics of the comb complex product system, summarizes the research the status quo of complex product system and modular design theory, the research design theory of complex product system especially the problem will exist modular design theory and method is applied to the complex product system, summarizes the related technology products modular system is complex, including module partition, module partition scheme and parameter evaluation module value planning, review the research progress and problems. (2) proposed modules of complex product system technology that based on weighted complex network community. First of all,. The function / complex product system correlation matrix eliminating method based on structural heterogeneity; secondly, to construct the complex product system component weighted complex network model, the component mapping nodes, the relationship between components and relationships between intensity maps for the weighted complex network edges and the right side, on the quantitative method of strength the relationship between function and structure; finally, using the improved GN algorithm to realize community structure of complex product system components weighted complex network discovery, with different values of several access network module module partition scheme, the formation of the program set, for the subsequent evaluation of module partition scheme to provide data base. (3) proposed the evaluation scheme of complex products the system module based on the method of interval valued intuitionistic fuzzy theory. Based on theory of product life cycle assessment scheme of complex product system module is established to Standard system, standard deviation index correlation coefficient to determine the weights of evaluation indexes based on the interval valued intuitionistic fuzzy number expression evaluation results, Karnik-Mendel algorithm is used to realize the arithmetic. Introducing the interval valued intuitionistic interval valued intuitionistic fuzzy sets to measure alternative forms and positive / negative ideal solution of relative closeness degree of fuzzy cross entropy, TOPSIS frame acquisition module partition scheme based sorting, so as to obtain the final scheme, used to support the follow-up module parameter planning. (4) proposed the module of complex product system based on customer demand distribution parameter value planning technology. After the construction of complex product system module response network model of customer demand, the problem was stripped three stage: firstly, research and analysis of customer requirements using QFD, determine the range and module parameters; secondly, using fuzzy clustering method to realize the Gu Clustering of customer demand, customer needs determine the optimum clustering scheme through clustering validity index, clustering number of customer demand value of one module parameters; finally, through the distribution of feature extraction of customer demand cluster centers, distribution of integrated distribution of all relevant customer needs can obtain module parameters, combined with the value of a number complex product system modular construction, for the retrofit design of direct application range and module parameters of spectrum. (5) based on the research results of typical products, provide a demonstration. The large tonnage crawler crane products as research object, based on the research results of the modular design. The value of planning including the construction of large tonnage crawler crane module product architecture and module parameters, which includes module division and module evaluation. The proposed complex product system The feasibility and effectiveness of the modular technology. This paper established a method system for complex product modularization, provide technical support for the construction method of modular product structure of complex product system and module parameters for the project planning, further research to lay the foundation, combined with the actual application technology of the method proposed in this paper to a modular design case of large tonnage crawler crane products, combined with the implementation of the project, has been recognized by companies.
