Fuzzy Comprehensive Evaluation of Work Safety Capacity for Construction Enterprises Based on Rough Set

From the angle of construction enterprises' work safety capacity, the research center is changed from traditional construction site safety management to work safety capacity management. First, we established evaluation index system of work safety capacity for construction enterprises. Second, we applied rough set theory to conduct index reduction in order to overcome the shortcomings of index redundancy and high computation complexity. Third, we used analytic hierarchy process (AHP) to confirm indexes' weight after reduction. Finally we applied fuzzy comprehensive evaluation to evaluate work safety capacity for construction enterprises.
