摘　　要：信息流网络是一个描述作战体系从发现目标到打击目标过程中信息在平台内部和平台之间进行处理和传输的有向加权网络,研究信息流网络的抗毁性对于提高作战体系效能有着重要意义。为此,首先将作战平台所包含的搜索、跟踪、制导和攻击功能模块划分为多个节点,同时考虑节点对信息的处理能力和节点之间的信息传输能力,构建一个有向加权信息流网络,并提出改进的节点度、连边介数和网络连通性计算方法以适用于有向加权信息流网络的性能评估。然后,在传统对节点和连边的攻击方式基础上,提出针对节点和连边的蓄意软杀伤和随机软杀伤2种攻击方式。最后,对比分析了不同攻击方式对信息流网络的影响,有效模拟了有向加权信息流网络的抗毁性评估过程。The information flow network is a directed weighted network that describes the process of information processing and transmission within and between platforms in an operational system from target detection to target strike.Studying the resilience of the information flow network is of significant importance for enhancing the effectiveness of the operational system.Therefore,the search,tracking,guidance and attack modules contained in the operational platform were first divided into multiple nodes.At the same time,considering both the node̓s information processing capability and the information transmission capability between nodes,a directed weighted information flow network was constructed.An improved method for calculating node degree,interface number and network connectivity was proposed to evaluate the performance of the directed weighted information flow network.Then,based on traditional attack methods on nodes and edges,two attack methods targeting nodes and connected edges were introduced:deliberate soft-kill and random soft-kill.Finally,a comparative analysis of the impact of different attack methods on the information flow network was conducted,effectively simulating the resilience evaluation process of the directed weighted information flow network.
