A novel local approximation approach for quantitative analysis of combat power index
-
摘要: 战斗力指数的定量化研究是军队实现信息化建设必须解决的难题。针对战斗力指数研究存在定量研究较少、方法精度较低、鲁棒性不强等问题,以及战斗力指数函数本身为复杂规则主导、多变量数学模型、影响因素强耦合等难以拟合的限制,受模糊逻辑理论中对规则的数学分析方法启发,提出了一种基于局部逼近的战斗力指数函数拟合方法,并结合神经网络强大的自学习和自推导能力,构建了相应的基于径向基神经网络(RBF)的定量计算模型。仿真对比实验表明,该方法比利用全局逼近的方法误差率低约2%和6%,且表现出更强的鲁棒性。该计算方法具有较强的实用性,而且具备向其他军事领域迁移的可能性,具备良好的工程应用前景。Abstract: The quantitative study of combat effectiveness index is crucial for the informationization construction of the military. Aiming to limits of quantitative research, low method accuracy, and weak robustness in the study of combat effectiveness index, as well as the limitations of complex rule dominated, multivariate mathematical models, and strong coupling of influencing factors in the combat effectiveness index function itself, inspired by the mathematical analysis methods of rules in fuzzy logic theory, a local approximation based method for fitting combat effectiveness index function is proposed. Combined with the powerful self-learning and self-deduction capabilities of neural networks, a corresponding quantitative calculation model based on radial basis function (RBF) is constructed. Simulation comparative experiments show that the proposed method has an error rate of about 2% and 6% lower than the current best performing method using global approximation, and exhibits stronger robustness. Our method has strong practicality, which can be migrated to other military fields, and has good engineering application prospects.
