External Evaluation of Power Supply Service Based on Zadeh Fuzzy Process

To improve the service quality of power enterprise, an index system for power supply service evaluation is constructed from the aspects of electricity customers’ perception and the service process of power supply enterprise. G1 method determines the weight of indexes Zadeh operator is used for synthesis process. This chapter combined Zadeh operator and the fuzzy synthesis, and a new evaluation method was proposed. Using this method to evaluate the power supply service at one of the regions of Guangdong Province in China, the result shows the disparity between the actual service performance and customer demands. Through the case, the method of improving power supply service is found out and the reasonableness of proposed method is demonstrated.
