Location-allocation problems are generally complex problems by involving many variables and data. In this paper, the authors aimed to assess the solution quality for location-allocation problems from facilities generated by the software TransCAD, a Geographic Information System for Transportation (GIS-T). Such facilities were obtained after using two routines together: facility location and transportation problem, when compared with optimal solutions from exact mathematical models, based on Mixed Integer Linear Programming (MILP), developed externally for the GIS.
