Abstract

In location problems we want to determine the best way to serve a set of clients, or communities, whose location and demand are known. This implies to decide the number and location of the facilities, the size or capacity of each facility, and the allocation of the demand points to the open facilities in order to optimize some objective function. The type of optimality criterion depends on the nature of the activities or of the equipment to be installed. Most location models deal with desirable facilities, such as warehouses, service and transportation centers, emergency services, and so forth, which interacts with the customers and where usually travel is involved. The typical criteria for such decisions include minimizing some function of the distances between facilities and/or clients. However, during the last two or three decades, those responsible for the areas overall development, where the new equipment is going to be located (i.e., central government, local authorities) as well as those living there, are showing an increasing interest in preserving the area’s quality of life.
