摘　　要：介绍一种基于Ｐｅｔｒｉ网模型、面向系统特征智能选择启发式派遣规则的柔性制造系统动态调度方法。仿真结果表明，其调度性能优于使用单一启发式派遣规则的方法，适合于解决柔性制造单元中随机、动态调度问题。This paper presents an intelligent dynamic scheduling method for flexible manufacturing systems(FMS), which is based on Petri net model and selects the appropriate heuristic dispatching rule(HDR) flexibly with respect to current system features. The results of simulation show that the presented method outperforms single dispatching rules and is particularly useful in tacking stochastic, dynamic scheduling problems in FMS.
