摘要
机组排班计划是航空公司运营管理计划的重要组成部分,因其NP-hard特性常面临组合爆炸而难以求解。针对这一问题,提出一种基于航班环的优化模型。在第一阶段考虑执勤时空衔接约束与执勤始发终到约束,构建了航班间的航班环模型;在第二阶段设计了结合改进的深度优先搜索算法(depth-first search,DFS)以及贪心算法完成对模型的求解。此外,提出了列生成算法下受限主问题模型(restricted master problem model,RMP),并运用该模型完成实验验证算例的求解。
Abstract
Crew scheduling is an important part of the operation management plan of an airline. Due to its NP-hard, it often faces combinational explosion and is difficult to be solved. Addressing the problem, a flight-loop-based optimization model was proposed. In phase one, considering the space-time connection constraint and the departure and arrival constraint for duty, a flight loop model between route segments was built; in phase two, the depth-first search (DFS) algorithm and greedy algorithm were incorporated to accomplish the solution of the model. In addition, a restricted master problem (RMP) model was proposed under the column generation algorithm, which was then used to solve the experimental validation examples.
