露天矿卡车调度的发车间隔控制及其随机性研究

露天矿卡车调度系统中,一个重要的性能指标就是电铲前卡车的排队长度,它直接关系到整个生产的效率。本文提出了一种发车间隔的控制方法,并在Matlab环境下进行了大量的仿真研究,研究中考虑了卡车在道路上的行驶时间与电铲装车时间这两种主要的随机因素的影响。研究表明,该法能有效地控制卡车排队长度,保持车流均匀,并完成产量计划。发车间隔控制是一种简单有效的解决排队问题的基本方法。

STUDY ON DEPARTING TIME INTERVAL CONTROL AND RANDOMICITY OF TRUCK DISPATCHING FOR STRIP MINES

A significant performance index in truck dispatching system of strip mines is the length of the queue of trucks at the excavators,which directly affects the efficiency of the whole production.A departing time interval control method is developed in this paper.Substantive simulation research is done in Matlab environment.The influences of two main random factors as the driving time of trucks and the loading time of excavators are considered in the research.The research shows that this method can availably limit the length of queue,keep traffic uniform and fulfill output plan.The departing time interval control is concise,effective and a basic method of solving the problem of queuing.
