采用系统容量有限的[M/M/c]:[∞/∞/FCFS]排队模型对露天矿机械化排土过程进行分析,构建了综合考虑购置费用、排土能力、运行成本以及车辆平均寿命等因素的综合灰色评价模型,以此确定汽车配置方案,并进行了实例验证。实例验证结果表明,该模型可达到优化配置的目的。最后对传统的排队论模型提出了相关的改进意见。
Based on the limited capacity system [ M/M/c ] : [ ∞ /∞/FCFS] queuing model, the process mechanized waste disposal in open pit mine are analyzed, a grey evaluation model in which the purchase cost, disposal capacity, operation cost and average useful life of vehicle are comprehensively took into account is constructed. The allocation of vehicles is determined by the model, and an experimental study is given for verifying the proposed model, the results show that the purpose of optimizing the allocation of vehicles can be reached by this model. Finally, some suggestions to improve traditional queuing model are putted forward.
