摘要
在综合考虑影响煤矿安全评价因素的基础上,建立了煤矿安全评价指标体系,应用粗集理论进行属性约简,提取核心影响因素,并用信息熵确定指标客观性权重,然后建立未确知测度模型对煤矿安全进行综合评价,提高了评价结果的客观性和准确性.
Established index system of coal mine safety appraisal, based on integrated consideration about the influencing factors of coal mine safety appraisal. It used the rough set to make property reduction, then distilled the core influencing factors. Then using information entropy confirm objective index weight, and employing the unascertained theory elicited the synthesizes appraisal of coal mine safety, which enhanced the object and accuracy of appraisal.
