Abstract: In this paper a covering model for locating facilities with time-dependent demand is introduced. Not only the facility locations, but also the instants at which such facilities become operative, are considered as decision variables in order to determine the maximal-profit decision. Expressed as a mixed nonlinear integer program, structural properties are derived for particular demand patterns, and a metaheuristic procedure is proposed as optimization tool.

Keywords: covering models, competitive location, dynamic demand, maximal profit, variable neighbourhood search
