Coal mine safety assessment based on rough set theory and analytical hierarchy process

Abstract：Safety evaluation mainly includes qualitative and quantitative methods.Qualitative methods are usually used to appraise the safety condition of coal mine enterprise.The results are lack of scientificalness, accuracy and subjectiveness.The former assessment method can't assign and measure the weight number of assessment indexes reasonable, so it is difficulty in appraise the comprehensive safety condition of coal mine enterprises.This paper firstly construct the hierarchical structure of coal mine safety assessment, and determine the weight number of safety indexes through combining rough theory and analytical hierarchy process (AHP) .Then pointed out that the comprehensive assessment based on rough set and AHP is a feasible assessment method, which is more corresponding to the practice of coal mine.
