飞机指派问题优化模型及算法研究

为了提高航空企业飞机排班计划的自动化水平,分析了航空企业飞机排班计划编制流程,将这个复杂组合优化问题分解为3个组合优化问题,重点研究了其中的飞机指派优化问题,归纳了要考虑的主要约束条件,以优化理论为基础,针对飞机排班计划优化问题中的关键问题—飞机指派问题建立了飞机指派优化模型,模型考虑了飞机与航班之间在机型、飞行区域、客流量等条件上的匹配要求,并给出了模型约束条件的编码方法,同时根据大量实际生产数据给出相应的惩罚系数表。为求解模型,构造了一种自适应单亲遗传算法,算法选用了适合模型的遗传算子,采用动态调整遗传算子操作概率的方式加快优化速度。采用航空公司的实际航班数据进行仿真实例研究结果表明,该模型和算法切实可行。
