摘要
分拣系统中 ,由于操作人员的参与 ,可能导致被分拣货物和装箱清单不一致。这主要是由于上包控制和货包信息的同步跟踪不可控所造成。为解决这个问题 ,该文提出受控计时扩展Petri网 ,在此基础上对自动分拣系统进行了建模 ,并分析了操作人员的控制作用。实际应用表明 ,受控计时扩展Petri网为具有人参与的物流系统提供了一种良好的建模方法。
Because of workman participating in sorting system, some sorted materials do not accord with their list, which is consulted from the uncontrolable. To solve this problem this paper presents controlled and extended time Petri net. Based on it a model of a sorting system was created. The workman's controlling roles are analyzed. The application demonstrates that the controlled and extended time Petri net provides a very good way for modeling of material flow system with some workmen.
