疫情局部封控下的航线网络修复策略分析

Selection of Route Network Repair Strategy Under Local Epidemic Containment

论文对疫情局部封控下的航线网络修复策略进行研究,设置航线网络修复场景,确定因疫情暂停航线的区域和航线网络修复路径备选方案,提出航线网络因子分配修复策略(RAS),采用基于粒子群优化算法(ASPSO)进行求解,以实现修复成本最小化目标。基于典型案例分析表明:航线网络因子分配修复策略综合了原有拓扑结构修复策略(OTRS)和拓扑结构调整修复策略(TARS),既可以避免长途航行,又可避免新航线引起的协调成本,航线网络修复成本较低,修复速度快,航线网络运行效率较高,能够实现最小的修复费用下航线正常运营的目标,能够为处于疫情局部封控条件及类似情景下的航空公司运营提供决策依据。

In this paper,the route network repair strategy under local containment of epidemic situation is studied,the route network repair scene is set up,the areas where routes are suspended due to the epidemic and the route network repair path alternatives are determined,the route network factor assignment repair strategy(RAS)is proposed.The particle swarm optimization algorithm(ASPSO)is used to solve the problem so as to achieve the goal of minimizing repair cost.The analysis based on typical cases shows that the airline network factor assignment repair strategy combines the original topology repair strategy(OTRS)and topology adjustment repair strategy(TARS),which can not only avoid long-distance navigation,but also avoid the coordination costs caused by new routes.The route network repair cost is lower,the repair speed is higher,the route network operational efficiency is higher.It can achieve the goal of normal route operation under the minimum repair cost,and can provide decision-making basis for airline operations under the condition of local epidemic containment and similar scenarios.
