【摘要】 建立了制造单元加工过程的Petri网模型,采用关联矩阵来表征Petri网模型结构,并由之获得可达标识并进而得到由初始标识到最终的不同的变迁序列,根据变迁序列和加工过程的对应关系得到优化的加工顺序。更多还原

【Abstract】 In this paper, the production process in manufacturing cell (MC) is modeled based on the Petri－net theory, the Petri－net model′s incident matrix is produced to represent the basic structure. The reachable markings and the various transition sequences from the initial marking to the finish marking can be obtained. According to the relationship between transition sequences and operation sequences, the optimum operation sequence can be realized.更多还原
