基于改进结构方程模型的陆军武器装备体系作战能力评估模型

作战能力评估对陆军武器装备体系发展论证和作战运用具有重要意义，其评估模型的构建又是其中最为关键的一项内容。分析基于改进结构方程模型（SEM）的陆军武器装备体系作战能力评估步骤，构建陆军武器装备体系作战能力评估指标体系，并对现有SEM进行改进。通过线性加权和法对多维度体系作战能力评估指标体系进行降维处理，提高SEM的计算效率，实现陆军武器装备体系作战能力的快速计算与综合评估。改进SEM中的聚合指标权重求解分别采用熵权法和层次分析法，将2种权重聚合指标值参与到改进SEM中计算的体系作战能力评估结果，与直接用SEM的体系作战能力评估结果进行对比。仿真实验结果表明，体系作战能力评估结果的变化趋势基本一致，实现了对改进SEM可信度和时效性的验证分析。

Evaluation Model of Land Force Weapon Equipment System Combat Capability Based on Improved SEM

The combat capability evaluation of weapon equipment system is significant for its development and operational applications，and the construction of evaluation model is the most critical aspect of combat capability evaluation. The evaluation steps of land force weapon equipment system combat capability were analyzed based on improved structural equation modeling (SEM)，an evaluation index system of weapon equipment system combat capability was constructed，and the SEM was improved by reducing the dimension of multidimensional capability index system of land force weapon equipment system combat capability based on linear weighted sum method. The computational efficiency of SEM is increased，and the fast calculation and comprehensive evaluation of combat capability is realized by using the improved SEM. The entropy weight method and the analytic hierarchy process method are used to calculate the weight of aggregation index in the improved SEM，and the capability evaluation results of two kinds of weight aggregation indexes participating in the improved SEM are compared with those of SEM. The simulated results show that the change trends of the evaluated results are basically the same，thus validating and analyzing the accuracy and timeliness of the improved SEM.
