In order to ensure the safe and stable operation of a power system, the performance evaluation of transformer windings after a short-circuit test can predict whether the windings are deformed in order to provide a useful reference for the operation and maintenance of the power sector. This paper proposes a method for evaluating the performance of transformer windings in order to improve the overall effectiveness of a winding evaluation. The index data obtained based on a short-circuit impedance method, frequency response method, and oscillation wave method are used in the algorithm proposed in this paper. First, the transformer winding performance evaluation index system is constructed. Second, the weight of each index is determined by analytic hierarchy process, and then the fuzzy comprehensive assessment method is introduced, and the fuzzy evaluation matrix is established, the evaluation results are calculated using the evaluation formula. Finally, the maximum membership principle is used to determine the performance level of the transformer winding on the evaluation results, and the evaluation results of the transformer winding state are obtained. The example shows that the evaluation level of the measured transformer winding performance can be obtained by this method as “good”. Compared with the traditional method, this method can simplify the evaluation while maintaining higher accuracy.

The government website is an important tool for the government to improve administrative efficiency and public service. Just as traditional government management needs performance evaluation, government websites also need performance evaluation. Based on the theory of Balanced Scorecard (BSC), this article puts forward a set of BSC performance evaluation index system for government websites and uses analytic hierarchy process (AHP) to establish the weight of all levels of indicators in the system. According to the characteristics of website performance evaluation, the qualitative and quantitative indicators are disposed in a unified fuzzy processing, and the performance of government websites is evaluated objectively and impartially by multi-level fuzzy evaluation method, which provides a scientific and feasible method for promoting the performance of government websites.

Abstract Performance evaluation of expatriate technicians is an important way for multinational corporations to effectively manage their expatriate technicians, which is crucial to the technological innovation of multinational corporations. This paper designs the performance evaluation index system of expatriate technicians, which includes work efficiency, professional competence, work attitude, and personal traits. Then, based on the C-POWA operator, the evaluation method of expatriate technicians is put forward. Lastly, using the index and method of evaluation of expatriate technician, four expatriate technicians’ performance are evaluated, and the results reveal that the index and method we put forward are scientific and practical.
