Application of combination weighting method in coal mine safety risk analysis

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.
