摘 要: 利用CPN TOOLs软件,对基本着色Petri进行赋时和分层的扩展,采用自上而下的方法,建立了集装箱码头作业系统的分层Petri网模型,其子网为赋时着色Petri网.基于实例,在集装箱码头作业系统的分层Petri网模型上进行仿真,根据前沿和堆场设备以及水平输送车辆的利用情况,分析了码头作业系统的瓶颈. In this paper, the hierarchical timed CP-net (HTCPN) is presented and the HTCPN model of container terminal system is established with CPN TOOLs in top-down manner. The HTCPN model is simulated based on a container terminal system. The bottleneck of container terminal system is analyzed based on the utilization ratio of quay crane ,yard crane and automated guided vehicle (AGV) in the simulation.
