【摘要】：為探索體系作戰(zhàn)信息流轉(zhuǎn)級(jí)聯(lián)失效的特點(diǎn)規(guī)律,抽象了作戰(zhàn)信息流轉(zhuǎn)的層級(jí)網(wǎng)絡(luò)結(jié)構(gòu),建立了基于任務(wù)約束的級(jí)聯(lián)失效模型。提出由物理層和邏輯層組成的信息流轉(zhuǎn)分層網(wǎng)絡(luò)結(jié)構(gòu),分析了網(wǎng)絡(luò)層間的級(jí)聯(lián)失效影響關(guān)系;引入任務(wù)協(xié)作因子改進(jìn)節(jié)點(diǎn)介數(shù)計(jì)算方法,根據(jù)作戰(zhàn)任務(wù)動(dòng)態(tài)生成信息流轉(zhuǎn)層級(jí)網(wǎng)絡(luò)結(jié)構(gòu),考慮節(jié)點(diǎn)功能屬性和信息交互方向,設(shè)計(jì)負(fù)荷重分配策略及失效判定條件,采用平均失效規(guī)模度量級(jí)聯(lián)失效影響。以空中進(jìn)攻作戰(zhàn)為例進(jìn)行仿真分析。結(jié)果表明,節(jié)點(diǎn)具有較小初始負(fù)荷及容量的網(wǎng)絡(luò),更易產(chǎn)生快速顯著的級(jí)聯(lián)失效;失效節(jié)點(diǎn)類(lèi)型不同,所產(chǎn)生級(jí)聯(lián)失效的規(guī)模和持續(xù)時(shí)間具有較大差異。仿真結(jié)果驗(yàn)證了模型的可行性與有效性,可為網(wǎng)絡(luò)結(jié)構(gòu)優(yōu)化設(shè)計(jì)、安全防護(hù)等提供有益借鑒。
[Abstract]:In order to explore the characteristics of cascade failure of operational information flow, the hierarchical network structure of operational information flow is abstracted, and a cascade failure model based on mission constraints is established. The information flow hierarchical network structure composed of physical layer and logical layer is proposed, and the cascade failure relationship between network layers is analyzed. The task collaboration factor is introduced to improve the calculation method of node meshes. According to the operational tasks, the hierarchical network structure of information flow is generated dynamically, and the load redistribution strategy and failure judgment conditions are designed considering the function attributes of nodes and the direction of information interaction. The average failure scale is used to measure the cascade failure effect. Take the air attack as an example to carry on the simulation analysis. The results show that nodes with small initial load and capacity are more likely to produce rapid and significant cascading failures, and the scale and duration of cascading failures vary greatly with different types of failure nodes. The simulation results verify the feasibility and validity of the model, and can provide useful reference for the optimization design of network structure and safety protection.
