飞机维修机库维修作业调度优化研究

With the constant increment fleet of aircraft, the demand of civil aircraft maintenance is increasing. In order to improve the efficiency of aircraft maintenance, the complex aircraft hangar maintenance scheduling problem is studied in the project. Specific contents are described as follows: First, the research on the relationship of aircraft parking stands arrangement and aircraft hangar maintenance efficiency, while considering time window, safety distance, routing barrier, and wings overlap, is investigated in both two and three dimensions. Second, a robust model of aircraft hangar maintenance scheduling problem is studied with the consideration of dynamic uncertainty circumstance aiming to adapt the random situation such as random arrival time. Third, a reasonable and high efficiency algorithm is proposed to solve the aircraft hangar maintenance scheduling problem. The innovations are described as followed: First, the research on the maintenance process in aircraft hangar shop. Second, the study on the effect of stochastic conditions on aircraft hangar maintenance. The research findings of this project improve the existing aircraft hangar maintenance operation and optimization theory, as well as, contributes to the science and applications.

随着我国飞机机队规模的不断扩大，民用航空器的维修需求也迅速增加，为了提高维修作业效率，本项目系统研究飞机维修机库中复杂维修作业调度优化问题。具体内容包括：分别在平面和立体作业环境中，研究机库中飞机停机机位和机库作业效率的关系，并考虑时间窗、安全距离、路径障碍和机翼重叠等实际限制条件；在动态不确定作业环境下，研究具有鲁棒性的飞机机库作业调度模型，使其能够适应随机进场时间等偶发情况；设计合理高效的求解算法，给出飞机维修机库作业调度问题的高效可靠解决方案。本项目的特色：探究飞机机库中的飞机维修作业过程；探索随机条件对机库维修作业的影响。该研究有助于完善现有飞机维修机库作业运筹管理与优化理论，具有重要的科学价值与应用潜力。

随着航空运输需求的快速发展，民航机队规模不断壮大，飞机维修行业也迎来了如雨后春笋般的爆炸式生长。飞机维护、修理和大修是确保航空安全和航空运输正常运行的重要环节，通常需要在机库中完成。在机库容量有限的情况下，如何尽可能地满足日益增长的维修请求成为了飞机维修服务公司亟待解决的新问题。在对机库维修计划进行编排时，需考虑每个时段服务的飞机不超出机库的容量限制，避免飞机产生碰撞和阻塞的风险，并对维修人员进行合理排班，降低飞机维修公司的运营成本，提高服务水平。具体内容包括：分别在平面和立体作业环境中，研究机库中飞机停机机位和机库作业效率的关系，并考虑时间窗、安全距离、路径障碍和机翼重叠等实际限制条件；在动态不确定作业环境下，研究具有鲁棒性的飞机机库作业调度模型，使其能够适应随机进场时间等偶发情况；设计合理高效的求解算法，给出飞机维修机库作业调度问题的高效可靠解决方案。项目成果包括，SCI/SSCI学术论文6篇，获得辽宁省“百千万人才工程”万层次人才、大连市本地高端人才青年才俊人才等荣誉称号2项；培养硕士生4名（2名已毕业）。
