Abstract

Passeport Vacances is an offer for school-aged children to discover a set of activities during holidays. For more than 30 years, it has been an established social function in several countries, including Germany and Switzerland. Proposed activities might occur several times during the Passeport Vacances. The assignment of activities to children is computed in order to maximize the children’s preferences, as well as to balance each child’s incurred cost, toward an equity goal. There are several sets of constraints associated with the assignment problem: no overlapping activities assigned to the same child, minimal and maximal ages per activity, minimum number of children for opening an activity, maximal size of a group for each activity, no similar activities assigned to the same child, no already assigned ‘lifetime’-activity per child, and at most one activity per period and per child. We propose a binary linear programming model that describes the assignment problem, report CPU computation issues regarding the model implementation, and report numerical results based on a state-of-the-art MIP solver. Tests where conducted with real data from the 2016 edition of Passeport Vacances in Morges.
