摘要: 为评估煤矿瓦斯爆炸的灾害风险,结合前景理论与模糊综合评价理论,建立风险评价模型。根据煤矿瓦斯爆炸的形成条件和事故致因理论,建立风险评价体系;运用前景理论,以统计推断计算的区间数期望值为参考点,确定各指标属性值为区间数的决策权重,结合模糊综合评价理论与区间数排序原理,建立基于区间数的煤矿瓦斯爆炸风险模糊综合评价模型;运用该模型对某地3座煤矿进行风险评估,风险评价结果与煤矿的生产实际情况一致。结果表明:该评价方法克服了人的有限理性行为对决策时的主观期望效用的影响,使评价结果更加客观、科学。

Abstract: In order to evaluate disaster risk of gas explosion in coal mine, a risk evaluation model was built on the basis of both the prospect theory and the fuzzy evaluation theory. And an evaluation system was also established based on the formation conditions of coal mine gas explosion and accident-causing theory. Having the aid of the prospect theory, the attribute values were determined as the weights of each interval number, by using the expectancy value of interval number as the reference point. A fuzzy comprehensive evaluation model was built for the risk of gas explosion in coal mine based on the interval numbers on the basis of both the fuzzy comprehensive evaluation theory and the ranking interval numbers principle. Finally, risk evaluations were performed for three coal mines by applying the model. The assessment result conforms with the real situation. The results show that the proposed evaluation method overcome the limited rational behavior of man's influence on the decisions of subjective expected utility, the evaluation results was more objective and scientific.

Key words: prospect theory, gas explosion, interval number, risk assessment, interval number sequence
