　　航路網(wǎng)絡(luò)是空中交通分配的載體,而交通分配是檢驗航路網(wǎng)絡(luò)的依據(jù),如何構(gòu)建基于交通分配的航路網(wǎng)絡(luò)生成便成了當(dāng)前空域規(guī)劃技術(shù)中的研究方向。論文基于鏈路預(yù)測理論、優(yōu)化理論,建立了上層為航路網(wǎng)絡(luò)生成,下層為交通分配的雙層規(guī)劃模型,采用基于鏈路預(yù)測的網(wǎng)絡(luò)拓?fù)渖善骱突谄玫淖顑?yōu)路徑搜索算法進(jìn)行航路網(wǎng)絡(luò)生成,采用NSGA-Ⅲ算法進(jìn)行交通分配。論文基于Python平臺NetworkX復(fù)雜網(wǎng)絡(luò)分析庫,采用中國大陸空域北京和上海飛行情報區(qū)57個機(jī)場、383個航路點、635條航段組成的航路網(wǎng)絡(luò)和187 975架次機(jī)場對交通流量進(jìn)行案例仿真。通過與現(xiàn)有航路網(wǎng)絡(luò)對比,交通分配運(yùn)行成本下降50.624%,飛行沖突系數(shù)下降33.564%,動態(tài)非直線系數(shù)下降7.830%。
