摘要
时间Petri网是描述和验证实时系统最常用的形式模型之一。建立基于时间Petri网的典型柔性制造系统模型,利用状态类分析方法,定量计算所有可行调度及其执行时间,进而获得最优调度,为复杂柔性制造系统的建模与调度提供有效的模型支持。
Time Petri nets are a popular format model for the specification and verification of real-time systems. In this paper, we build a typical flexible manufacturing system model based on a time Petri net, and quantitatively analyze all feasi- ble schedules and their execution delays by using a state class method, and then obtain an optimal schedule. Our method of- fers an effective support for the modeling and scheduling of complex flexible manufacturing systems.
