Abstract
When using the entropy method to assign weight, as the discrete degree of an index is too large, the weight of the index will be very large. In order to solve this problem, using the ideas of Analytic Hierarchy Process method(AHP) to improve the entropy method, the index weights are solved through judgment matrix, which is obtained by the pair comparisons of indexes' difference coefficients. The normalization method of maintaining the same index information entropy of the index initial data, the steps of calculating the mapping values from the 1 to 9 scale of AHP method to the 1 to 9 scale of improved entropy method, and the methods of constructing judgment matrix based on the information entropy and solving the index weights are given. The six index weights of fighter air-to-air combat capability are assigned using the entropy method and the improved entropy method respectively, and the fighter air-to-air combat capability is evaluated. The results show that the improved entropy method makes up the shortcoming of entropy method, the assignment weight result is more reasonable, and air-to-air combat capability evaluation results are more accurate.关键词
