| 摘 要： | 用混合整数规划法求解露天矿生产计划编制问题(OMPSP),其算法的时间复杂度为指数阶。提出一种基于成本流的露天矿开采锥模型(CFCM)。采用图论的方法将矿床块段模型抽象为节点的集合,用有向边表示成本流,将所有正价值节点与其开采锥内负价值节点相连形成初始CFCM。研究采用线性规划的方法对成本流进行合理分配而形成最终CFCM的方法,并应用于实际露天矿山的计划编制工程中。研究结果表明:CFCM能极大地减少用混合整数规划法求解OMPSP时的整数变量个数,适应于复杂的实际OMPSP,其计算结果与工程实际结果较吻合,为解决实际OMPSP提供了一种新的有效方法。

| Abstract: | The complexity of mixed integer programming method for solving open-pit mine production scheduling problems(OMPSP) was exponential complexity.The cost-flow based mining cone model(CFCM) was presented.The deposit block model was abstracted into the node collection by the method of graphic theory.Cost-flows were used to connect each positive-value node with the negative-value nodes in its excavation cone to form the initial CFCM,and the cost-flows were denoted by directed edges.Furthermore,the linear programm... |
