摘　　要：对模糊柔性制造系统的建模和调度进行了研究。定义了一种具有模糊区间速率的混杂Petri网模型,提出了模型的迁移使能和迁移引发语义,定义了弱使能迁移的模糊使能规则,给出了模型动态演变算法。建立了模糊柔性制造系统调度的模糊线性规划模型,并对典型的工业实例进行了分析。研究结果表明,基于所定义的混杂Petri模型能够有效地描述和分析模糊柔性制造系统。The modeling and scheduling of fuzzy flexible manufacturing system were studied, a hybrid Petri nets model with fuzzy interval speed was proposed. The enabling and firing semantics of transitions of the proposed model were presented, Fuzzy enabling rules for weak enabling migration were defined. Dynamic evolution algorithm of the model was also provided. A fuzzy linear programming model was established to find the optimal scheduling policy in fuzzy flexible manufacturing system, and typical industrial instance was also analyzed. An application example showed that the proposed model could effectively describe and analyze fuzzy flexible manufacturing system.
