Abstract The geographical distribution of the population of the city of Santiago, Chile, has changed significantly in recent years. In spite of this fact, the location of the fire stations in the city has remained unchanged. We propose a model for the optimal location of the fire stations and a fleet assignment for the Santi- ago Fire Department (hereafter referred to as SFD), aimed at maximizing the number of events attended to with a predefined standard response. There are several different types of resources (stations and vehicles), and several differ- ent types of events in which the same types of vehicles are used. The model also considers multiple time periods. The results of the model are compared with respect to the current location of fire stations and fleet assignment in the SFD. We analyze various possible current and future scenarios, using a forecast based on historical data. Our results show that by optimally reallo- cating the resources a 10 to 30% increase can be achieved in the number of emergency calls that are attended to with an adequate response in time and number of vehicles, without the need for additional fire stations or vehicles. * Corresponding author.
