A fuzzy set theory approach to the aircrew rostering problem

The paper develops a model to solve the aircret rostering problem consisting of the assignment of crew members to planned rotations. The crew rostering problem includes the construction of personalized monthly schedules (rosters). The basic algorithm to solve the aircrew rostering problem developed in this paper is a modification of the ‘day-by-day’ heuristic method. An approximate reasoning algorithm is used to determine the strength of the decision maker's preference to assign a specific rotation to a specific pilot. The developed model is tested on a numerical example whose dimensions are characteristic of small- and medium-sized air carriers.
