摘要
编组站到解系统仿真属于离散事件系统仿真,是对所有有关实体状态变化过程的模拟。实体包括编组站固定设备实体、技术作业实体和临时实体。根据实体状态在编组站到解系统各项作业过程中的变化情况,实体又可以分为二元状态实体、矢量状态实体和多元状态实体等3类。可以将同类实体的状态及其他相关属性构建为行矩阵,不同类别实体之间的作业关系构建为二维矩阵,使整个编组站到解系统仿真过程用数个矩阵的循环运算表示。仿真结果表明,到达场股道数量对驼峰解体能力的发挥存在1个阈值,当低于阈值时,充分利用驼峰解体能力和提高编组站整体解体能力的主要决定因素是股道数量;到达场股道、列检组和驼峰调机的数量变化对解体能力的影响是非线性的,存在1个相对较为合理的取值范围,可以通过综合各种因素仿真确定。
The simulation of the arriving and breaking-up system in marshalling station belongs to discrete event system simulation. It is a simulation calculating for the changing processes of all related objects status. The objects include static state equipment objects, technical operation objects and temporary objects. These objects have been divided into dualistic status, vector status, multi-status objects based on the changing process in the operation of the marshalling station. This paper converts the status, properties and relation of these objects to matrix and use circular matrix calculating to realize the marshalling station simulation. The simulation result shows that the effect of the sidings number in the arriving yard to hump capability has a threshold value. When sidings number is under this value, the humping capability is decided by sidings number. The simulation result also shows that the effect of the sidings number, shunting locomotive, train inspection to humping capability are nonlinear. Each factor has a reasonable range. This factor can be integratedly decided through simulation.
