Safety Culture Construction Evaluation Based on Combination Weighting and Fuzzy TOPSIS Methods

Safety culture plays an important role in the prevention of accident. Positive safety culture can effectively improve worker's safety conscious and reduce the accident rate. This paper is aimed to present a fuzzy decision making method for objectively evaluating enterprise safety culture construction level. Based on evaluation indicators of safety culture construction level, combination weighting method in view of spearman rank correlation coefficient was adopted to determine weights of evaluation indicators, andfuzzy technique for order preference by similarity to an ideal solution (fuzzy TOPSIS) of safety culture construction level was proposed by introducing triangular fuzzy number. Filing in four Chinese companies as an example to carry on comprehensive evaluation, evaluation results show that the proposed method can reflect actual situation of enterprise safety culture construction level.
