由于其在大量物料搬运中的灵活性 ,铲 车作业在露天矿物料搬运系统中被普遍采用。在典型的采矿作业中 ,无论是调度模式还是非调度模式 ,都是数台汽车配 1台铲。采用“期望等待时间”概念 ,ARENA模拟模型通过一个调度员程序清楚地表明了矿山生产率的改善 ,特别是当汽车车队规模接近最佳值时。 Due to its flexibility in handling large quantities of material, forklift operations are commonly used in open pit material handling systems. In a typical mining operation, whether it is scheduling mode or non-scheduling mode, several cars are equipped with a shovel. Using the concept of “expected waiting time”, the ARENA simulation model clearly shows the improvement in mine productivity through a dispatcher program, especially when the fleet size approaches the optimal value.
