基于熵权和物元分析的矿山安全避险“六大系统”可靠性评价

为了更加准确合理地评价“六大系统”的可靠性等级，运用熵权法与物元分析理论建立了“六大系统”可靠性评价模型。基于“六大系统”的组成成分，提出了影响“六大系统”可靠性的32项指标，采用物元变换理论构建“六大系统”可靠性评价的物元体系，计算单个待评估指标与设定评价等级的相关度，然后利用熵权法确定待评估指标的权重，最后根据待评估指标与设定等级的综合相关度确定“六大系统”的可靠性级别。研究结果表明：该方法综合考虑了各项评估指标对评价体系的影响，评价结果与实际情况相符，能够准确、客观地反映“六大系统”的建设情况。

Reliability Evaluation of Mine’s Six-System Based on Entropy Weight and Matter Element Analysis

To evaluate the reliability level of mine’s six-system more accurately and reasonably，an evaluation model of six-system was constructed based on entropy weight method and matter element analysis theory. Based on the composition of six systems，32 indexes that affect the reliability of six systems were proposed，the matter element system of six-system reliability evaluation was built through matter element transformation theory，and association degree of individual index to setting assessment level was calculated.Then the weight of indexes to be evaluated were determined by entropy weight method，and the reliability level of mine’s six-system was determined according to comprehensive association degree of evaluation and setting level.The study results show that the evaluation result is identical to actual situation owing to the constructed model comprehensively considered all the reliability affecting factors to the assessment system，which can reflect the reliability situation of mine’s six-system accurately and objectively.
