基于作战环的空间信息时效网关键节点分析模型

体系作战中的空间信息网络具有复杂动态性特点,其本身带有不同于其他网络的时间和空间尺度,具有动态的节点关系和不可逆的时间关系等特征属性。为了刻画这些特征属性在空间信息网络构建、网络关键节点分析中的作用,引入时效网络,提出了空间信息时效网关键节点分析模型。首先,基于标准作战环提出了基于时效网络的作战环模型;其次,侧重网络边属性的时效性建立了空间信息时效网络模型;最后,以作战环为基础构建了网络拓扑结构的关键节点分析指标与模型,仿真实验结果验证了其有效性。

Key nodes analysis model for space information temporal network based on operation loop

In the system of systems combat, the space information network is complex and dynamic. It is different from other networks at time and space scales, with dynamic node relation and irreversible time relation. In order to reflect the effects of these features on modeling of the space information network and analyzing of network key nodes, the temporal network is introduced and the key nodes analysis model for the space information temporal network is proposed. Firstly, under the standard operation loop, the model of operation loop based on the temporal network is given. Then, the space information temporal network model focusing on the network edge’s timeliness is proposed. Finally, from the angle of topology structure, the metrics and model of key nodes analysis based on the operation loop are constructed. The simulation results verify the efficiency of the model.
