Aiming at the high subjectivity of traditional training evaluation methods for shore-to-ship missile weapon systems, a training effect evaluation index system of shore-to-ship missile weapon system is constructed based on network analysis.An “equivalent treatment” module is designed to reduce computational complexity, which realizes the mapping from weapon system training data to the secondary indicators.The Analytical Network Process (ANP) and Variable Precision Rough Set (VPRS) are used to establish the training effect evaluation model, and the expert mean confidence method is introduced to reduce the subjectivity and contingency of the evaluation process.The SD software is used to solve the model, and the weight coefficient of the training evaluation index of the shore-to-ship missile weapon system is obtained.The results verify the effectiveness of the method.
