一、引言大型露天矿铁路运输的装运设备的合理数量及最优配比是一个具有重要经济意义的问题。从50年代起,人们曾经用数学分析法进行过大量研究,但是一直未能获得满意的结果,主要是因为铁路运输装运过程的组织是相当复杂的,表现在: 1.装运过程中,装载、运行、卸车、等待时间都是随机变量,用确定型平均时间描述此过程会失真; 2.运输是在许多个装卸点之间进行,运行方向要根据当时各装卸点完成任务情况
I. INTRODUCTION The reasonable quantity and the optimal ratio of the shipping equipment for large-scale open pit railway transport are an issue of great economic significance. Since the 1950s, a great deal of research on mathematical analysis has been conducted but no satisfactory results have been obtained. The main reason is that the organization of the rail transport shipment process is quite complex, as follows: 1. During loading, Run, unloading, waiting time are random variables, with a fixed average time to describe the process will be distorted; 2. Transport is carried out between many loading and unloading points, the direction of operation according to the completion of the task at each loading and unloading points
