面向安全硬约束的煤矿生产物流效率优化研究

在保证安全生产前提下实现效率最大化是煤炭生产企业亟需解决的现实问题。本文结合煤矿生产物流系统的复杂性特征，首先从人员素质、机械装备、环境改善、安全管理、应急救援等方面确定了煤矿生产物流的安全投入指标，运用响应曲面法分析了安全指标与安全水平间的作用关系，确定了煤矿生产物流安全硬约束条件；然后以效率最大化为目标函数、安全目标和资源投入为约束条件，构建了煤矿生产物流效率优化模型；最后通过实例验证了模型的有效性及适用性，为安全生产前提下实现资源优化配置，提高煤矿生产物流效率提供了科学依据。

Efficiency Optimization of Coal Mine Production Logistics Under Safety Hard Constraint

Improving efficiency under safety production is an urgent task for coal mine enterprises. Combined the complexity of coal mine production logistics, safety indexes are selected from personnel quality, machinery, environment, safety management and emergency rescue in the paper. The relationship of safety indexes and safety level is analyzed by response surface method and safety hard constraint of coal mine production logistics was obtained. Then an efficiency optimal model of coal mine production logistics is established through setting efficiency maximization as function, safety level and resource investment as constraints. Finally, case study shows the validity and applicability of efficiency optimal model. This research provids a scientific method to improve efficiency realize resource optimal allocation under the condition of safety production logistics.
