Research of security resource allocation model of coal mine production logistics system based on maximum information entropy

针对煤矿生产物流系统动态时序、复杂多变及不确定性的特征,充分考虑煤矿生产物流各子系统的客观因素,确定了煤矿生产物流系统安全资源指标体系;采用信息熵方法对各安全资源指标进行定量化计算分析,构建了基于最大信息熵的安全资源配置模型,研究了安全资源的合理优化配置问题。实例应用结果表明,运输子系统及排水子系统属于重点增加安全资源投入的子系统,开采子系统及通风子系统属于削减安全资源投入的子系统。运用最大信息熵方法进行安全资源配置,可为提高煤矿安全生产水平、优化煤矿安全资源配置提供理论支持。

According to characteristics of dynamic time sequence,complexity and uncertainty of coal mine production logistics system,security resources index system of coal mine production logistics system was determined that fully considered objective factors of various subsystems of the coal mine production logistics system,and security resources index was quantitatively calculated and analyzed by information entropy method.The safety resource allocation model based on maximum information entropy was built,and the optimization allocation problem of security resources was studied.Application results of example show that transportation subsystem and drainage subsystem belong to focus on increasing security resources investment,and mining subsystem and ventilation subsystem belong to cut safety resource investment.The safety resource allocation based on maximum information entropy method can provide theoretical support for improving level of coal mine safety production and optimizing coal mine securityresource allocation.
