矿山短期生产计划优化的多目标遗传粒子群算法
|
摘要
针对露天矿山生产的基本特征及短期生产计划的编制要求,从露天矿山的品位及经济成本最小化的角度出发,构建了露天矿短期生产作业计划优化模型。以MATLAB软件为平台,采用遗传粒子群混合智能算法对模型进行求解。以某石灰石露天矿为工程背景进行研究,将研究结果与露天矿实际生产指标进行对比验证。结果表明:该模型适用于露天矿短期采掘作业生产计划的编制,优化结果保证了矿山生产作业出矿品位、出矿量及生产利润三者之间的平衡,有利于提高矿山的经济效益。
In view of the basic characteristics of open-pit mine production and the requirements of short-term production plan,and in order to obtain the ore grade and the minimal economic cost of open-pit mines,an optimization model of shortterm production plan is established. Based on MATLAB software,the hybrid intelligent algorithm of genetic particle swarm optimization is used to solve the model. Taking a limestone open-pit mine as a case,the research results are compared with the actual production indexes of the open-pit mine. The results show that this model is suitable for making the plan of the shortterm mining production. The optimization results guarantee the balance among the three kinds of mine production indexes,including ore grade,ore output and production profit. As a result,this optimized model is helpful to increase the economic benefit of open-pit mine.
