基于扩展着色赋时Petri网的板材FMS建模及分析

Modeling and Analysis of the Sheet Metal FMS Based on Extended Colored Timed Petri Nets

提出带有决策库所的扩展着色赋时Petri网 (ECTPN)建模方法 .建立了板材FMS的ECTPN模型 ,通过ECTPN模型对板材FMS运行中的潜在冲突作出分析 .结合调度规则 ,ECTPN模型能准确刻画板材FMS的运行过程 。

This paper presents a modeling method of Extended Colored Timed Petri Nets(ECTPN)that is based on CTPN and has the decision places. An ECTPN model of the sheet metal FMS is completed, the possible conflicts in the FMS are analyzed via the ECTPN. Combined with the scheduling rules, the ECTPN model can accurately simulate the FMS running process, so it builds good conditions for further analyzing and evaluating the complex system.
