This paper proposes a methodology to solve theproblem of proper allocation of classrooms. Amethodology is based on heuristics techniques aswell as the use of the metaheuristic Ant ColonyOptimization. To achieve this goal, it is initially describedthe problem. Thus, the mathematical modelis developed in order to ensure that each scheduledevent is assigned to an adequate classroom.Additionally, the attendance timing of the studentsenrolled to each event is determined. The computationaleffort of the proposed algorithm is testedusing known instances in the literature. Finally, wepropose future work to improve the results achievedin this work and visualize himself viability ofthe implementation of the methodology in the LibreUniversity of Pereira.
