摘要： 网络化作战装备体系是具有要素多元、关联紧密、动态演化等特点的典型复杂系统,脆性是其固有属性,直接影响着网络化作战装备体系的安全性和运行稳定性。针对网络化作战装备体系的脆性控制问题,首先,界定装备节点、关联关系、网络化作战装备体系等概念,抽象网络化作战装备体系结构,分析装备体系脆性传播机理,设计脆性控制因果回路图,建立脆性控制微分动力学模型;其次,提出免疫控制、隔离控制和综合控制3种策略,给出脆性控制效果的度量方法;最后,以网络化防空作战装备体系为例,仿真分析了脆性风险调控阈值、脉冲控制覆盖数量、综合控制策略参数对高脆性风险的持续时间和脆性风险程度的影响。实验结果表明,当脆性风险调控阈值提高25%时,免疫控制、隔离控制和综合控制策略对应的高脆性风险的持续时间分别缩短了53.2%,44.9%,42.2%,脆性风险程度提高了24.5%,1.5%,20.4%;在脉冲控制覆盖数量提高1倍的情况下,高脆性风险持续时间差异不显著,脆性风险程度降低了9.3%,1.5%,10%;在综合控制策略参数比值提高约1.3倍的情况下,高脆性风险持续时间和脆性风险程度分别降低了5.9%,8.3%。研究结果验证了模型与策略的可行性和有效性,为探索网络化作战装备体系脆性控制过程与规律提供了新的思路和方法。
