组合赋权法在煤矿安全风险分析中的应用

Application of combination weighting method in coal mine safety risk analysis

鉴于煤矿安全风险分析中指标权重需综合考虑主客观两方面的需求,提出了一种层次分析法和熵权法相结合的组合赋权法。该方法使用层次分析法和熵权法分别得到指标的主观权重和客观权重,利用乘法集成法将主观权重和客观权重融合,得到更全面、准确的组合权重。通过案例分析验证了该方法在煤矿安全风险分析应用中的有效性。

In view of requirement that index weight in coal mine safety risk analysis needed to consider subjective and objective aspects comprehensively,a combination weighting method combining analytic hierarchy process and entropy weight method was proposed.The method uses analytic hierarchy process and entropy weight method to obtain subjective weight and objective weight of index respectively.The multiplication integration method is used to combine the subjective weight and the objective weight to obtain more comprehensive and accurate combination weight.The case analysis verifies effectiveness of the method in application of coal mine safety risk analysis.
