摘要: 针对集装箱码头立体轨道式传送系统网络的复杂结构,采用面向对象随机Petri网(Object-Oriented Stochastic Petri Net,OOSPN)建模方法,简化结构实现层次化建模,并运用随机Petri网进行性能分析。从而检测出系统各个特征状态的执行效率,有效地发现了系统瓶颈,并提出了改进方案。在此基础上,通过WITNESS仿真软件实现码头作业的模拟。结果表明该方法能有效构建和分析集装箱码头立体轨道式传送系统网络复杂系统,并获得其效率指标和统计数据。

Abstract: Object-Oriented Stochastic Petri Net(OOSPN) is utilized concerning the complexity of container terminal tridimensional rail transmission system network.It simplifies the structure and modeling with object-oriented and hierarchy idea,while the efficiency of each state is detected based on Stochastic Petri Net performance analysis.Thereby,it finds the system bottleneck which also provides reference for the improvement of the program and then the model of terminal system is implemented by using WITNESS.The efficiency indicators are obtained by analysis and construction of container terminal transmission system as well.
