露天矿短期生产调度建模研究

针对数学规划模型得到的露天矿短期生产调度在实际生产中的不可行现象，引入开采区域规整性概念用以表示模型结果的现实可行性，并提出基于距离的规整性测度。该规整性测度的形式是非线性的，影响其应用。提出了一种方法将其转化为线性表达式。将该规整性测度作为目标函数添加到一般的露天矿短期生产调度模型中，建立了多目标规划模型，并使用点估计加权和方法求解。计算结果表明，新建立的模型能够得到现实可行的露天矿短期调度。

Research on modeling of short-term production scheduling for open pit mine

To solve feasibility problem of the short-term production scheduling of open pit mine , a new concept, " regularity of a mining region", was introduced. A distance-based regularity measurement was proposed, but the nonlinear measurement has limited its application. To overcome the limitation, a method was put forward to convert it to a linear representation. Adding the distance-based regularity measurement as an additional objective function to a general open pit mine production scheduling model, a multi-objective programming model was formulated. The point -estimated weighted-sums method was applied to solve the proposed model. The computation results indicated that the new model could achieve a more practical open pit mine production scheduling.
