机型分配问题是飞机、机组排班问题的基础,是整个航班计划中的关键环节。文章针对市场需求高度不确定的情况,建立了两阶段随机混合整数规划模型,其中第一阶段考虑机族层次的分配,确保每个航节均分配1种且仅有1种机族,第二阶段根据进一步的市场需求信息及预测,考虑每个航节所分配的机族内具体机型的分配问题。针对建立的模型,设计了Benders分解算法,并通过算例验证了该模型较传统确定型模型更具有效性,能够为航空公司的机型分配提供决策支持。
機型分配問題是飛機、機組排班問題的基礎,是整箇航班計劃中的關鍵環節。文章針對市場需求高度不確定的情況,建立瞭兩階段隨機混閤整數規劃模型,其中第一階段攷慮機族層次的分配,確保每箇航節均分配1種且僅有1種機族,第二階段根據進一步的市場需求信息及預測,攷慮每箇航節所分配的機族內具體機型的分配問題。針對建立的模型,設計瞭Benders分解算法,併通過算例驗證瞭該模型較傳統確定型模型更具有效性,能夠為航空公司的機型分配提供決策支持。

The airline fleet assignment is the basis of aircraft scheduling decisions and crew scheduling decisions, which is the most crucial link of the airline flight scheduling. Aiming at the highly uncertain market demands, this study proposes a two-stage stochastic mixed-integer programming approach. The first stage makes only family-level assignment decisions and ensures that each flight leg is covered by exactly one aircraft family. The second stage performs the detailed assignments of fleet types within the allotted family to each leg according to forecasted market demands. In the model, the Benders decomposition algorithm is developed. The instance verifies the pro?posed model is more effective than the traditional ones and it can provide the foundations for decision making of airline fleet assignment.
