摘要:

本文提出了一种有效的启发式加速列生成并行解决飞机的定价问题的尾部分配问题(TAP)。该方法是能够实现相当大的改善,在解决时间为现实生活中的测试实例,从两个主要的印度航空公司。本文考虑了根据航空监管机构对个别飞机进行维修路线的不同限制。我们还提出了一个变量固定启发式,以提高解决方案的完整性。约束编程和列生成的混合在加速解析过程中发挥了重要作用。

英文摘要:

This article proposes an efficient heuristic in accelerating the column generation by parallel resolution of pricing problems for aircrafts in the tail assignment problem (TAP). The approach is able to achieve considerable improvement in resolution time for real life test instances from two major Indian air carriers. The different restrictions on individual aircraft for maintenance routing as per aviation regulatory bodies are considered in this paper. We also present a variable fixing heuristic to improve the integrality of the solution. The hybridization of constraint programming and column generation was substantial in accelerating the resolution process.
