摘要
为了提升复杂系统多阶段任务的成功率,建立了指挥所系统情报获取、情报处理、决策控制与响应执行4阶段的单个阶段任务可靠性模型,基于各任务阶段网络的节点特征给出了重要度指标,以此辨识相应阶段网络中的关键节点,并通过热备份系统确定关键节点的冗余方法,考虑关键节点运行维护成本和节点地理位置成本约束,以多阶段任务可靠性最大化为目标函数,建立了多阶段多任务冗余策略优化模型,对冗余优化前后任务可靠性进行对比,验证模型的有效性。
In order to improve the success rate of multi-stage mission of a complex system,a single stage mission reliability model of command post system is established,which includes such four stages as information acquisition,information processing,decision-making control and response execution.Based on the characteristics of network nodes for each stage,the importance index is given to identify the key nodes in the corresponding stage network,and the redundancy method of the key nodes is determined by hot backup system.Then the operation maintenance cost of the key nodes and the cost constraints of the geographic location of nodes are considered,the maximum reliability of multi-stage mission is regarded as the objective function,redundancy strategy optimization model of multi-stage and multi-mission is established.Finally,the reliability of tasks before and after redundancy optimization is compared to verify the effectiveness of the model.
