Automatic rifles scheme effectiveness evaluation is of great significance for Automatic rifle development and application.At present,the evaluation of Automatic rifles scheme is mainly aimed at the middle and later stages of Automatic rifle development,while the evaluation research on the initial stage of Automatic rifle development is less,and the evaluation subjectivity is strong,and the evaluation results are greatly influenced by the evaluation experts.This paper studies the objective evaluation of the initial stage of Automatic rifle scheme development.Because the evaluation index system based on tactical and technical indexes is often used now,the index value is subjective and comprehensive in the early stage of Automatic rifle scheme development,and the reference value for scheme structure design is low.In this paper,a Automatic rifle evaluation index system based on mechanism elements is proposed,that is,taking scheme evaluation as the target layer,tactical and technical indexes as the criterion layer,and Automatic rifle mechanism elements as the criterion layer.It can directly introduce the mechanism elements parameters of Automatic rifle in the early stage of development into the scheme evaluation,avoid directly using the comprehensive tactical and technical indicators,and the evaluation is more in line with the characteristics of the early stage of development.According to the characteristics of each index,different methods of index assignment are adopted.The interior and exterior ballistic models,the gun launching dynamic models and the human gun launching dynamic models are built for the dynamic indexes,and the method of quantitative giving and measuring the physical parameters is determined for the static indexes.In view of the limitation of index comprehensiveness and independence,subjective evaluation and objective evaluation,and the fuzziness of index data in the evaluation ofAutomatic rifle scheme,three methods based on correlation analysis,entropy weight and Grey target theory based on Mahalanobis distance are proposed to evaluate the initial scheme of Automatic rifle development.the credibility of the scheme evaluation is explored.This paper presents a method for calculating the reliability of evaluation based on AHP.Taking the credibility of evaluation results as the goal,the evaluation process as the guide,and the key steps as the elements,the evaluation index system is constructed.the credibility of evaluation results is calculated.
