Some Technologies And Their Applications Research For Recursive Modeling And Recipe Reconstruction Of Configuration Product

This dissertation takes the configuration product as the investigative object. On the basis of anslyse on the characteristics of configuration product design, the recursive model of configuration product is established. And the corresponding technologies of configuration product which include dynamic reconstruction for configuration process, feedback reconstruction for configuration recipe, assembly mapping and assembly sequence reconstruction for configuration product, are deeply studied. The theory and methods presented in the dissertation have been proved to be corrected and advanced by the applications in electrostatic precipitator industry.The organization structure of full text is as follows:In chapter 1, A review and history of the theory research and application situation of configuration product design technology which can respond rapidly to customer requirements, and the new research issue is pointed out by the induction of correlative technique. Finally, the contents and significance of the dissertation is put forward.In chapter 2, Product modeling is the basis of study on configuration product design and recipe reconstruction. In this chapter, the theory and methods of configuration product recursive modeling is put forward according to the recursive properties of product design process. And, the recursive model of configuration product is established from three respects:(1)configuration template,(2)configuration knowledge,(3)configuration design.In chapter 3, In order to obtain the configuration recipe with accuracy and efficiency, the configuration process should be reconstructed. In this chapter, the theory and methods of configuration process reconstruction based on dynamic design structure matrix(DSM) is put forward. First, the configuration process DSM is constructed by mapping the data flow diagram(DFD) model of configuration tasks. Secondly, the dynamic DSM of configuration process is obtained through introducing the view of dynamic customer requirements DSM and the view of dynamic constraints DSM. Finally, the configuration tasks are reorganized by the decomposition and tearing of DSM. So, the optimization of configuration process is realized.In chapter 4, The reconstruction of configuration recipe can sovle the problem of congfiguration product update and maintenance. The integrated process model of product configuration is established based on capturing and recording the process and information of configuration design. The feedback mechanism of configuration information is used. So, the configuration knowledge is always in the latest status by collecting, treating and updating configuration information. Guiding of configuration feedback information, the configuration recipe is reconstructed based on the reuse of configuration knowledge. In chapter 5, The technologies of assembly information mapping and assembly sequence reconstruction are very important for configuration product development and design. In this chapter, assembly information of configuration product is acquired through mapping from product configuration region to assembly region. Thus, the information of product configuration is reused in the reconstruction of assembly sequence. Assembly sequence reconstruction model of configuration product is established by defining the automatic assembly planning unit. And as a result, Assembly sequence reconstruction of configuration product is realized.In chapter 6, the theory and method discussed above are applied in electrostatic precipitator industry. The system of recursive modeling and recipe reconstruction of configuration product(FDCP) has been developed and its main functions and the realized techniques are described and presented. The application and implement result of FDCP system have proved that the theories and the methods have good practical value.In chapter 7, All achievements of the dissertation are summarized so as to put forward the further research.
