【摘要】 利用特种车运输作业过程与排队过程的相似性,将其抽象为一类具有特殊规则的多台多级排队系统:设备被视为服务台,车列占用设备的作业过程被视为服务过程,车列间以及车列和设备间的约束关系被设计成特殊的服务规则。仿真过程中,设备占用时间可被精确记录,从而为定量查定运输设备利用率提供了新的方法。仿真实例表明,新建模型正确,仿真策略简单易行,数据结果反映实际。更多还原

【Abstract】 A multi-service multi-queue queuing system has been abstracted based on analysis of the characteristics of special train transport system,where switch set and railway line section are considered as service station,and the running through of train set above them as the service process.Train sets run according to route and served by group of service stations.Dead-lock simulation is discussed and special checking is designed to prevent it from happening.Simulation experiments show that the established model is correct and the usage rate of switch set and railway line section can be calculated more precisely in this way.更多还原
