Research of the Evaluation of Bidding Agency′s Performance Based on Fuzzy and Optimized Entropy Weight

Based on ″Fujian Province′s tentative method of project bidding agency′s credit rank evaluation″,″Heilongjiang Province′s tentative method of project bidding agency′s credit rank evaluation″ and so on,a three level evaluation index system of bidding agency′s performance is established and the evaluation index′s subjective weight is obtained. And then,by using entropy theory and fuzzy mathematics,a comprehensive evaluation model of performance evaluation is set up with optimized entropy. Finally,an example is calculated and analyzed to indicate that it is scientific,objective,reasonable and feasible to evaluate with this method. And it will be good to limit bidding agent′s behavior and enhance the grade of service by linking bidding agency′s income with the result of performance evaluation.
