摘　　要：针对大型选矿生产线运行和管理特点,分析了选矿企业生产成本、原矿处理量、精矿品位、金属回收率等综合生产指标在计划层、执行层和控制层间的交互关系;说明了选矿企业计划调度主要特征是将综合指标逐层分解优化为日生产线指标的思想;建立了在保证产品质量合格前提下总成本最小为目标和在保证合理精矿品位的前提下,以减小精矿库存、最大限度地满足设备生产能力为目标的计划与调度两阶段级联优化模型;提出了决策选矿生产线日原矿处理量和精矿品位与尾矿品位等生产指标的生产计划调度优化方法,并应用于某选矿企业制造执行系统(Manufacturing execution system,MES),取得显著应用成效.For the production line operation and management of mineral processing, the interactions of comprehensive indices, such as mineral processing cost, raw ores quantity, concentrate grade, metal recovery and so on, were analyzed at planning, execution, and control layers, We also illustrated the main feature of planning and scheduling in mineral processing enterprises, which is to decompose and optimize the comprehensive production into the production indices of a day. A two-stage hierarchical model of planning and scheduling was established, which can minimize the overall cost for ensuring products quality and maximally utilize equipment capacity for ensuring rational concentrate grade, decrease the concentrate inventory. The approach of planning and scheduling, which makes decision on day production indexes of raw ores quantity, concentrate grade and tailing grade, was proposed in this paper. It has been applied to a manufacturing execution system （MES） of a mineral processing enterprise, and satisfactory results have been achieved.
