基于融合权集对云的煤矿安全评价及应用

Evaluation of coal mine safety based on fusion weight and set pair cloud and its application

为合理评价煤矿安全状态,针对煤矿安全影响因素多、指标体系关联度复杂等问题,提出融合权与集对云的安全评价模型。运用云理论特征值修饰集对分析联系度,兼顾系统的模糊性与不确定性,并引入融和后的各指标最优权重,得出系统综合云联系度;绘制等级云图判定系统安全状态及偏向趋势;结合煤矿实例进行验证。结果表明:案例煤矿所处安全状态为较安全,有偏向一般安全状态微势。分析结果与实际相符,且充分考虑煤矿安全评价体系的随机性,该模型可为煤矿安全评价提供理论指导。

In order to reasonably evaluate the safety status of coal mine,aiming at the problems of many influencing factors of coal mine safety and complex correlation degree of index system,a safety evaluation model of fusion weight and set pair cloud was proposed.The cloud theory characteristic value was used to modify the connection degree of set pair analysis,taking into account the fuzziness and uncertainty of the system,and introducing into the optimal weight of each index after the fusion,the comprehensive cloud connection degree of the system was obtained.The level cloud map was drawn to determine the safety state and bias tendency of the system,and the verification was carried out by using the actual case of coal mine.The results showed that the safety state of the case coal mine was relatively safe and tended to the general safety state in a micro potential.The analysis results were consistent with the reality,and the randomness of evaluation system for coal mine safety was fully considered,which can provide theoretical guidance for the evaluation of coal mine safety.
