Redundancy Optimization Model of Command Post System Based on Multi-stage Mission Reliability
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.
