Research On The Integration And Optimized Configuration Of Manufacturing Resources In Collaborative Manufacturing

As a kind of advanced manufacturing paradigm in network economy and knowledge economy environment, collaborative manufacturing (CM) emphasizes inter-enterprise collaboration and resources sharing in the whole society. The goal of CM is to realize the lower cost and higher efficiency of product designing and manufacturing process. Therefore, the share and optimized utilization of manufacturing resources dispersing in enterprises through network is one of important characteristics of CM. The resources integration platform that can integrate all kinds of resources and provide all kinds of functions will become one of important technically enabled tools for CM, and will effectively support implementation of CM in enterprises.In this thesis, the manufacturing resources integration problem in CM environment is discussed, including the architecture of integration platform, manufacturing resources integration framework, manufacturing resources modeling method, manufacturing resources optimized configuration method, and system realization.With reference to operation mechanism of grid, a grid-based CM resources integration architecture is proposed which consist of manufacturing resources management system, and manufacturing resources optimized configuration system.Based on analysis of current situation in manufacturing resources integration, a resources integration framework based on Web Services is presented, and the web ontology language (OWL) is chosen to describe manufacturing resources.According to the characteristic of CM, the two levels optimized strategy of manufacturing resources optimized configuration is proposed, which are the optimization of manufacturing partners and the optimization of Physical Manufacturing Unit (PMU). For optimization of manufacturing partners, a multiple attributes evaluation system of partner selection is presented, the artificial neural network trained by a Structure-improving particle swarm optimization algorithm is proposed to solve the problem. For optimization of PMU, LMP (logical manufacturing process) and LMU (logical manufacturing unit) are used to describe collaborative manufacturing task, an improved algorithm based on GA is proposed to solve the problem.Finally, the prototype system of CM resources integration platform is developed, it contains three modules: user register, manufacturing resources management and manufacturing resources optimized configuration.
