Combination weighting-based weapon system efficiency assessment method and evaluation method

Abstract

The invention provides a combination weighting-based weapon system efficiency assessment method and evaluation method. The assessment method comprises the steps of establishing a weapon system efficiency assessment index system and determining index values; determining subjective weights of the indexes of the index system by an index scale analytic hierarchy process; determining objective weightsof the indexes of the index system by an entropy weight method and a deviation maximization method, and correcting the indexes with the weight values exceeding upper limit values of the weights of theindexes; by adopting a least square and relative entropy-based principle, combining the subjective and objective weights to obtain combined weights of the indexes; and calculating a comprehensive system efficiency value by a weighted sum method, thereby obtaining an efficiency assessment result. According to the assessment method, the problem of excessively large weights of part of the indexes possibly occurring in an objective weighting method is avoided; the weights can objectively reflect importance degrees of the assessment indexes; the obtained assessment result can fully consider subjective wishes and engineering practical experience of an assessor, and reflects the objectivity of index data; and the obtained system efficiency assessment result is more accurate.

Description

technical field [0001] The invention relates to the field of weapon system performance evaluation, in particular to a weapon system performance evaluation method based on combination weighting and a weapon system evaluation method. Background technique [0002] With the rapid development of information technology and the upgrading of weapons and equipment, the development of weapons and equipment has also completed the transformation from emphasizing weapon performance to emphasizing the effectiveness of weapon systems. System effectiveness is the measurement of the degree to which a weapon system completes specified tasks. How to objectively and accurately evaluate the system effectiveness of weaponry has become an important topic and research direction in weapon development and construction, equipment demonstration, and combat application. However, in practical engineering applications, different evaluation methods have their own defects. In terms of index weighting, the A...

Problems solved by technology

However, in practical engineering applications, different evaluation methods have their own defects. In terms of index weighting, the AHP relies too much on the subjective experience of experts, and the entropy weight method may cause a single index to determine the final evaluation result. Moreover, the method used to evaluate the effectiveness of weapon systems is single, and the evaluation results obtained are somewhat one-sided, and the advantages of different evaluation methods have not been better utilized
