Cockpit Crew Pairing Problem in Airline Scheduling: Shortest Path with Resources Constraints Approach

Increasing competition in the air transport market has intensified active airlines’ efforts to keep their market share by attaching due importance to cost management aimed at reduced final prices. Crew costs are second only to fuel costs on the cost list of airline companies. So, this paper attempts to investigate the cockpit crew pairing problem. The set partitioning problem has been used for ...

A Subsequence Generation Approach for the Airline Crew Pairing Problem

In this paper we consider an important problem for the airline industry. The widely studied crew pairing problem is typically formulated as a set partitioning problem and solved using the branchand-price methodology. Here we develop a new integer programming framework, based on the concept of subsequence generation, for solving the set partitioning formulation. In subsequence generation one res...

Solving a robust airline crew pairing problem with column generation

In this study, we solve a robust version of the airline crew pairing problem. Our concept of robustness was partially shaped during our discussions with small local airlines in Turkey which may have to add a set of extra flights into their schedule at short notice during operation. Thus, robustness in this case is related to the ability of accommodating these extra flights at the time of operat...

A Stochastic Programming Approach to the Airline Crew Scheduling Problem

Traditional methods model the billion-dollar airline crew scheduling problem as deterministic and do not explicitly include information on potential disruptions. Unfortunately, the effort used to optimize crew schedules and reduce crew costs is often wasted as flight schedules are often disrupted. Consequently, airlines spend a great deal of time and money optimizing crew schedules in the plann...

Airline Crew Scheduling with Time Windows and Plane-Count Constraints

Generation Approach to Airline Crew Scheduling

The airline crew scheduling problem deals with the construction of crew rotations in order to cover the flights of a given schedule at minimum cost. The problem involves complex rules for the legality and costs of individual pairings and base constraints for the availability of crews at home bases. A typical instance considers a planning horizon of one month and several thousand flights. We pro...
