摘要

武器系统作战效能的评估具有重要意义。针对作战效能评估过程中影响因素复杂、小样本、非线性等问题，引入基于最小二乘法的支持向量机回归算法，用于作战效能的学习与预测。为了提高预测精度，引入差分进化算法进行支持向量机的参数优化选取。以地地导弹武器系统效能为例，分别采用 BP神经网络算法、经典支持向量机算法与本文算法进行仿真计算，结果表明差分进化支持向量机算法可很好地实现武器系统作战效能评估，具有较好的计算精度。%It is of great significance to evaluate the operational effectiveness of weapon system. With regard to the problems such as complicated impact factors,small sample and nonlinearity,the least square support vector machine was used to study and predict the evaluation of operational effectiveness. When establishing the parameters of SVM,Differential evolution was introduced to enhance the accura-cy of the prediction. With the evaluation of surface to surface missile as an example,this new method, BP neural network and traditional SVM were used for simulation calculation. It is shown that the meth-od of LS-SVM with Differential Evolution works well for the evaluation of operational effectiveness with a better computing accuracy.
