Abstract:

The criterion system of evaluation of combat measurement for an early-warning aircraft is built，and then the exponential algorithm for the interval number is put forward. The weights of qualitative indexes are ascertained by adopting the interval eigenvector method, and the weights of quantitative indexes are ascertained by adopting the interval-number eigenvector method and information entropy method. Then the standardization methods of qualitative indexes and quantitative indexes are presented, and a method of index aggregation based on the relationship of weight summation and product with the form of the interval number is proposed. Finally, the validity of this method is verified by an example.
