摘要:

针对复杂对抗环境下地空导弹系统假目标数量配比优化问题,提出一种基于生存概率、效费比和惩罚函数的多目标决策方法。首先,建立双参数可变的动态威布尔分布模型,刻画目标被发现识别概率随时间的变化规律,并结合火力分配构建目标生存概率计算模型。其次,综合考虑部署空间、时间及经济成本等约束条件,设置不同决策权重,构建融合作战价值、效费比和惩罚项的效用函数,进而建立真假目标数量配比优化模型。最后,结合典型应用场景仿真分析,验证模型与参数的有效性。结果表明,所提模型在持续对抗条件下能够更精确地评估系统生存概率并优化假目标配置数量,可为不同作战阶段提供差异化决策依据。

Abstract:

To address the optimization problem of decoy quantity ratio for surface-to-air missile system in complex adversarial environments, a multi-objective decision-making method based on survival probability, cost-effectiveness ratio, and penalty functions is proposed. Firstly, a dynamic Weibull distribution model with two variable parameters is established to characterize the time-varying probability of target detection and identificaiton, and a target survival probability calculation model is constructed in conjunction with firepower allocation. Secondly, by incorporating constraints such as deployment space, time, and economic costs, different decision-making weights are set to develop a utility function that integrates combat value, cost-effectiveness ratio, and penalty terms, thereby forming an optimization model for the allocation ratio between real and decoy targets. Finally, simulation analysis is conducted based on typical application scenarios to verify the effectiveness of the model and parameters. The results indicate that the proposed model can more accurately evaluate the survival probability of the system and optimize the number of decoy configurations under sustained adversarial conditions, providing differentiated decision-making basis for different combat stages.

Key words: two-parameter Weibull distribution, decoy, cost-effectiveness ratio, survival probability, multi-objective optimization
