[Abstract]:In the face of the rapid market changes and the increasing degree of product customization, the manufacturing industry is faced with the enormous challenge of how to respond quickly to the market demand. The traditional rigid automatic production line can improve the efficiency through mass production. Although flexible manufacturing system can shorten the production cycle of the product, but the investment is too large and the capital recovery period is too long, therefore, Reconfigurable manufacturing system (RMS), a new manufacturing system which combines the characteristics of mass production and flexible manufacturing system (FMS), has emerged as the times require. The selection and layout optimization of equipment, the reliability of equipment and system, the quantity of in-process cache and its optimization are the key technologies in the design and reconfiguration of reconfigurable manufacturing system. In this paper, the reconfiguration optimization of reconfigurable manufacturing system will be studied from these aspects. Configuration reconfiguration of reconfigurable manufacturing system is further analyzed and discussed on the basis of equipment layout and planning of traditional manufacturing system. The reasonable placement of all kinds of equipment, such as logistics handling equipment, under certain constraint conditions, and the quantity of manufacturing equipment, the capacity of equipment, the reliability of equipment state, the load of equipment, Due to the influence of the quantity of in-process cache and the processing process, the dynamic of production and the complexity of market demand have more emphasis on the reconfiguration of reconfigurable manufacturing system. In this paper, the reconfiguration characteristics of reconfigurable manufacturing system are studied, and the relationships among reconfigurable manufacturing system configuration, in-process cache and equipment reliability are discussed. The reliability of equipment in reliability engineering is introduced into configuration reconfiguration of manufacturing system. By associating equipment reliability with manufacturing system reconfiguration and realizing joint decision, referring to the traditional equipment layout method of manufacturing system, adopting the assembly of manufacturing equipment in the space of facility module and manufacturing resources, configuration parameters, A reconfigurable manufacturing system configuration reconfiguration optimization method is proposed by combining process information flow. The complexity of reconfigurable manufacturing system and system responsivity parameters are introduced. Based on the research and analysis of manufacturing system layout, the reconfigurable manufacturing system configuration optimization method is proposed. Combined with the actual level of manufacturing industry, starting with the modular management of equipment such as automatic machine tools, this paper analyzes the material handling distance, logistics transportation cost, equipment production capacity, equipment reliability, system complexity, etc. Based on the theory and methods of information entropy theory, fast response principle, integer linear programming, ant colony optimization algorithm, order clustering algorithm, and so on, the system rapid response and other important factors affecting configuration reconfiguration of manufacturing system, such as information entropy theory, fast response principle, ant colony optimization algorithm, order clustering algorithm, etc. The optimal selection model of manufacturing resources for reconfigurable manufacturing system is established. The algorithm of reconfigurable manufacturing system configuration reconfiguration optimization is designed. The concepts and calculation methods of complexity and responsiveness of reconfigurable manufacturing system are given. This paper provides a new idea for dynamic reconfiguration of manufacturing system configuration, and discusses the unification of configuration reconfiguration, productivity and cost of reconfigurable manufacturing system. It also provides the method option for the enterprise to realize the reasonable reconfiguration layout of the equipment and the quick response to the market demand.
