综合考虑低碳低成本的露天矿卡车运输优化研究

Research on Truck Transportation Optimization in Open-Pit Mine Considering Low Carbon and Low Cost

针对露天矿山的卡车运输问题,将降低碳排放量和节约运输成本作为两个优化目标,建立一个关于17个装载点、4个卸载点的多目标线性规划数学模型,利用MATLAB软件分别采用传统的线性规划法和NSGA-Ⅱ法对模型进行求解,并将考虑低碳条件的模型运算结果与没有考虑低碳条件的实际结果进行相比。研究结果表明:综合考虑低碳低成本的运输模型研究不仅能提高经济效益,还能降低矿山卡车运输环节中的碳排放量。因此,在研究矿山卡车运输规划问题时,将降低碳排放量作为优化目标之一进行规划具有重要研究意义。

Aiming at the truck transportation problem in open-pit mine,a multi-objective linear programming mathematical model with 17 loading points and 4 unloading points was established to reduce carbon emissions and save transportation costs as two optimization objectives.The traditional linear programming method and NSGA-Ⅱmethod were respectively used to solve the model by MATLAB software,and the results of the model considering low carbon conditions were compared with the actual results without considering low carbon conditions.The comparing results show that the transportation model considering low-carbon and low-cost can not only improve economic efficiency,but also reduce carbon emissions in mine truck transportation.Therefore,it is of great significance to reduce carbon emissions as one of the optimization objectives in the study of mine truck transportation planning.
