In this article a mathematical formulation for the problem of base location, ambulance allocation and relocation in multiple periods of time in a planning horizon is proposed. This problem is relevant for the planning of emergency services, especially in large urban centers where traffic conditions and population's concentration change during the day. These char-acteristics lead to the need of such services being dynamic enough to adjust to the change of city conditions in terms of traffic speeds and demand; in addition, the number of ambulances is usually elevated, as well as the number of districts in which the city is divided. Thus, the proposed model aims to maximize the probability of one determined call being served within a given covering time. We also describe a real world application for São Paulo's São Paulo's emergency system.
