摘要

针对提高空中交通航路网络运行效率的问题,本文提出了航路网络关键节点优化与“三区”避让设计相结合的网络设计方法.首先,给出了航路网络关键节点优化与“三区”避让设计的模型,并利用遗传算法对航路网络设计问题进行了求解;应用分析表明:优化设计后的航路网络相比现行航路网络,在运行成本、非直线系数、连接度、可达性等性能指标上均有大幅改善,从而证明该方法的正确性.%To solve the problem of improving the air route network (ARN) efficiencies, this paper proposes a methodology of key network nodes optimization and the restricted airspace avoiding. Firstly, the model of key network nodes optimization and the re-stricted airspace avoiding is established. Then, genetic algorithm (GA) is used to solve this model. Finally, practical applications analysis shows that the optimized ARN is better than current ARN on the performance metrics such as the operating cost, the non linear indicator, the connectivity, the reachability, etc. It is proved that the optimization method is efficient and correct by the actual cases.
