摘　　要：现有指挥信息系统韧性研究忽略了需求变化对其韧性过程的影响,无法反映系统遭受攻击后的韧性能力与任务需求的关系。引入正常功能水平、最低功能水平和预期功能水平3个变量,提出需求显著上升、需求基本持平和需求显著下降3种韧性模式;针对韧性过程中功能水平下降和自适应恢复2个阶段,提出抵抗力增强和冗余度提升策略,定义措施效果函数,建立韧性优化模型,运用分组背包问题的近似动态规划算法求解;以某区域联合防空指挥信息系统为例,进行仿真实验,验证需求变化对指挥信息系统韧性优化的影响。结果表明,为适应复杂恶劣战场环境下不同场景作战需求,指挥信息系统应选用合理的韧性模式,并统筹考虑敌方攻击强度、经费预算和应对策略等相关因素。Now available research on the resilience in Command Information System is in ignorance of the impact of demand changes on its resilience process,and is unable to reflect the relationship between the resilience ability of the system after being attacked and task requirements.Three variables of normal performance,lowest performance and expected performance are introduced,and three resilience models of significantly increased demand,basically flat demand and significantly decreased demand are proposed.In view of the two stages of functional level decline and adaptive recovery in the process of resilience,a strategy of resistance enhancement and redundancy enhancement strategies is proposed,the measure effect function is defined,a resilience optimization model is established,and the approximate dynamic programming algorithm of the group knapsack problem is used to solve the problem.Taking a certain of Regional Joint Air Defense Command Information System as an example,a simulation experiment is conducted,and the impact of demand changes on the resilience optimization of the Command Information System is verified.The results show that in order to adapt to the operational requirements of different scenarios in complex and harsh battlefield environment,the Command Information System should select a reasonable resilience mode,and the comprehensive relevant factors,such as enemy's attack intensity,funding budget,coping strategies,and so on,should be taken into account.
