The problem has applications in situations where the service provided by the facility is insensitive after a given threshold distance (eg. fire station location). In this work, we propose a global optimization algorithm for the case in which there are lower and upper limits on the numbers of customers that can be served / O objetivo no problema de localiza??o de uma facilidade com dist?ncias limitadas ? minimizar a soma das dist?ncias da facilidade para seus clientes, por?m com um limite em cada uma das dist?ncias onde, ap?s esse limite, o impacto na fun??o objetivo torna-se constante. O problema tem aplica??es em situa??es onde o servi?o fornecido pela facilidade ? indiferente depois de um limiar maximo (ex. localiza??o de um corpo de bombeiros). Nesta disserta??o, s?o propostos algoritmos de otimiza??o global para o caso em que existem limites inferior e superior no numero de clientes atendidos
