空中进攻作战安全返航通道容量评估

Evaluation of Safe Return Channel Capacity in Air Offensive Operations

针对军航战时空中进攻作战安全返航通道容量评估问题,提出节点合流调控元胞自动机模型(MR-CA模型)。根据空中进攻作战安全返航通道设置构型,聚焦通道交叉处的节点运行特性,将节点安全间距保持量化到合流规则中,研究不同可接受间隔条件下节点合流通道最大流量。并基于节点合流通道的交通运行特性,建立最小风险通道进入时间窗,将容流平衡调控的时间节点前移,在战略管理和预战术管理中消解个体战机在节点处的潜在航迹冲突,实现最大通行能力。仿真结果表明:节点合流后通道容量随间隔减小而增大,最大达到102架/h;在最小风险通道可进入时间窗范围内,通过MRCA模型在决策圆处对战机进行动态调控,能够保证节点安全合流,实现流量最大化。

In order to evaluate the capacity of the safe return channel of offensive operations in the time and space of military aviation warfare, this paper proposes the node confluence control cellular automata model (MRCA model). According to the configuration of the safe return passage in air attack operations, focus on the operational characteristics of nodes at the intersection of the passage, quantify the safe spacing of nodes into the confluence rules, and study the maximum flow of the passage before and after the nodes under different acceptable spacing conditions. And based on the traffic operation characteristics of the channel before and after the node, the minimum risk channel entry time window is established to move forward the time node of capacity balance regulation, eliminate the potential conflict of the fighter at the node in the strategic management and pre tactical management, and achieve the maximum traffic capacity. The simulation results show that the channel capacity increases with the decrease of the interval after the node confluence, and the maximum is 102 frames/h. Within the time window that the minimum risk channel can enter, the MRCA model is used to dynamically control the aircraft at the decision circle, which can ensure the safe confluence of nodes and maximize the flow.
