DEA with Weight Constraints for Evaluation of Work Safety Supervision
نویسندگان
چکیده
In this paper, a data envelopment analysis (DEA) model with weight constraints is proposed to evaluate the work safety supervision in 18 districts. Conventional evaluation approaches of the work safety supervision only consider the simple data such as the number of accidents and the number of death in the accidents. There are two major shortcomings: the weights of criteria are difficult to determined, and the different inherent risky levels of districts are not considered. Therefore we introduced the DEA method to address these issues. The results show that the evaluation by using DEA model is more objective and reasonable than the conventional approaches.

Data Envelopment Analysis (DEA) is a method for measuring the efficiency of peer decision making units (DMUs) with multiple inputs and outputs. The traditional DEA treats decision making units under evaluation as black boxes and calculates their efficiencies with first inputs and last outputs. This carries the notion of missing some intermediate measures in the process of changing the inputs to...
