Fuzzy-Entropy Theory Comprehensive Evaluation Method and Its Application in Building Construction Safety

In order to improve the safety management level of construction site, a new kind of safety evaluation method using the combination of fuzzy mathematics and the entropy theory was put forward. According to the hierarchical analysis, the evaluation index system of the safety management was firstly established. Then, the safety inspection table for the site was designed. At last, the weights and membership of the second class indexes were calculated and the membership matrix of the first class indexes was generated by fuzzy evaluation method. At the same time, the weights of the first class indexes were calculated using the entropy theory. Aimed at the evaluation results, some corresponding measures for improving the safety management level of the construction site was put forward. The results show that the hybrid method, which can overcome the shortcomings of each single method, is feasible, practical and operational in construction site safety assessment.
