In the ligut of the demand for the use of missile weapon combat, combined with the technical characteristics of the anti-ship missile weapon system, the influence factors of battlefield environment were introduced based on the tradi? tional evaluation model. The evaluation index system of anti-ship missile weapon system and the improved evaluation mod? el were established. Meanwhile, in view of the complexity of the capability of missile weapon system, the analytic hierarchy process and set pair analysis method were used in the comprehensive treatment of the evaluation index. The analysis showsed that the improved model could effectively reflect the integrated operational effectiveness of practical environment, and could provide more practical support and help for the training of actual combat conditions.
