Improvement of Analytic Hierarchy Process and its Application for Coal Mine Safety Assessment

Abstract:

The calculation of weigh value and consistency of the judgment matrix of analytic hierarchy process (AHP) were studied in this paper. And the study was applied for coal mine safety assessment. Due to the particularity and complexity of the coal mine environment, to make sure the comprehensive assessment for coal mine system safety, analytic hierarchy process was usually used. It is an important problem to solve the weight value and consistency of the judgment matrix when applying analytic hierarchy process. To obtain the weight value and ensure the consistence of the judgment matrix is the main research direction of AHP. The genetic algorithm was applied to calculate the weight value and the consistency of the judgment matrix. And fuzzy comprehensive evaluation method was applied to evaluate the safety condition of the coal mine system with the method of weight value solution in this paper. Case study shows that the calcuation resuts of applying genetic algorithm to calculate idnex weight value is better than additional methods.
