煤矿矿区生产效率预测的SD方法

SD-Method for Efficiency Prediction in Mining Production

1 问题的提出煤矿矿区职工人数和效率是反映矿区生产发展、工资增长和需要、进行生活福利设施建设的重要指标。在制定矿区发展规划时,要对矿区原煤生产人员、全员效率、职工人数等进行动态预测。这里介绍一种预测煤矿矿区生产效率的SD方法。 2 系统动态学及其在煤矿中应用简介系统动态学或称系统动力学,

SD-model is set up in this paper for efficiency prediction in mining production, which is programmed by use of the multi-function variable imitating language of PD-PLUS, it was employed in the variable prediction of the production scale schemes of the five mining districts in shuangyashan city.
