矿山生产调度计算机多目标决策模型的研究

COMPUTER-BASED MULTITARGETS DECISION-MAKING MODEL FOR PRODUCTION SCHEDULE IN MINE

由于采矿工艺自身的特殊性,致使矿山企业的生产调度决策采用一般单目标规划模型很难满足要求,因此,必须采用多目标决策模型才能合理地解决这一问题。多目标规划方法是单目标方法的新发展,它将单目标规划下的绝对约束改变成非绝对函数目标,并按优先等级,不同程度地予以满足,因而它总能找到一个最优解。矿山生产调度模型的建立,除了必须遵循一般的步骤以外,还必须充分了解和掌握不同采矿方法的工艺要求,以便从中提取工艺要求控制变量,并确定其优先级别,建立指标偏离函数。

Because of the specialities of mining technology, single target planning model is unable to meet the requirements of production schedule. So it is needed to use a multi-targets decision making model, to solve the problem properly. Multi-targets planning method is & new development of single target method, it turns ths absolute confinement in single target planning into non-absolute functional targets which, to a more or less degree , can be reached accorching to priority sequence, so as to always find a optimum solution. For the establishment of production schedule model of mine, e'xcepting general procedures to be followed, the technological requirments of different mining methods should well understood so as to sele'ct technological control variables, decide priority sequence and establish index deviation on functions.
