摘要
针对解决离散制造系统控制过程中可能出现的冲突、死锁等问题,将赋时Petri网和着色Petri网两者相结合,根据柔性制造系统的元素建立了拥有4个CNC机床加工中心,4条工件生产线的赋时着色Petri网模型。仿真结果表明,该方法能有效解决冲突、死锁等问题。
To solve the problems such as such as conflict and deadlock in the discrete manufacture process control system, we combine the timed Petri nets with the colored Petri net to establish a timed and colored Petri net model, which includes 4 operation centers and 4 product lines according the elements of the flexible manufacturing system. Simulation results show that the model can solve the above mentioned problems.
