Abstract:
The bidline scheduling problem with equity arises in several North American airlines. It consists of determining anonymous monthly schedules, called bidlines, that will be subsequently assigned to the crew members according to their bids and seniority. These bidlines must satisfy safety and collective agreement rules. Furthermore, to ensure an equity between the employees, each bidline should have as much as possible the same number of days off and the same number of credited (paid) hours. In this paper, we propose an approximate set partitioning type formulation for this problem and two heuristics for solving it. The first one is a standard branch-and-price heuristic that relies on a rounding procedure to derive integer solutions. The second one is obtained by combining this first heuristic with a dynamic constraint aggregation method that was recently proposed in the literature. Computational results show that, for the largest tested instances, the dynamic constraint aggregation heuristic can produce better quality solutions in a fraction of the computational time required by the standard branch-and-price heuristic.

For an airline company, managing schedules is a mathematical puzzle. In fact, it is such a complex mathematical problem that it is impossible to solve perfectly. At Air Transat, for example, a company that employs thousands of people, one must take into account constraints from collective agreements, vacation time, and family obligations, without forgetting airport schedules, and all this while saving every drop of fuel!

Abstract:
In this paper, we report the story of the GENCOL team and of the optimization software of the same name. This is first of all the history of a collaboration that has lasted for thirty years between François Soumis and Jacques Desrosiers, HEC Montreal and École Polytechnique de Montréal, the research centers CRT and GERAD, and the spin off companies GIRO and AD OPT.
