摘　　要：针对露天矿卡车实时调度应用比较普遍的Modular公司D ispatch系统动态规划法存在的问题,提出了目标产量完成度与当前车流饱和度的概念,论述了以这两个概念为基础的实时优化调度准则.以车流规划结果为基础,充分考虑系统随机因素的影响,兼顾卡车运输距离,实现了实时调度的整体最优.不仅适用于铲车数量匹配的情况,而且适用于铲车数量匹配失调的情况.既适用于空车调度,也适用于重车调度,比动态规划法的通用性和适用性更强,调度结果更合理,优化效果更好.经在露天矿使用证明,生产效率提高了8.0%-17.8%Regarding the current situation and problems, which exist in Modular Dispatch dynamic programming system that is widely used in open-pit truck real-time dispatching, two concepts for the completion of production target and the current truck flow saturation were proposed, and based on which the guideline of real-time optimized open-pit truck dispatching method was dissertated. Based on the results of truck flow programming, and the system stochastic factors and the transportation distance being taken into account, the truck real-time dispatching was optimized in its entirety. This method is not only suitable for the instance of shovel-truck matched, but also applicable for that of shovel-truck mismatched. And it also can be applied to empty truck dispatching as well as heavy truck dispatching. This method being used in an open-pit mine, it has been proved that production efficiency could be increased by 8.0% - 17.8%. The result shows this method has better applicability and practicability.
