The continuous process of transformation of the market forces the companies to think not only on themselves, but on the whole supply chain, in which they are inserted. Currently, the main goal is the reduction of their diverse costs of distribution, making use of new technologies or better systems, without forgetting to keep or improving its level of service. This study considers a physical distribution system that operates with one distribution center (DC) and 44 small trucks. Departing everyday from the DC the trucks supply all customers that belong to the Metropolitan Region of Rio de Janeiro. In this thesis some proposals for the door-to-door configuration of the distribution network of a great industrial company will be examined, in the Metropolitan Area of Rio de Janeiro, to reach lower costs, less waste and greater efficiency. The current system is evaluated and diverse configurations of modification in the system`s structure are examined, including the introduction of one or more deposits, in the Metropolitan Area, assisting the central deposit, in order to reduce the traveled distances, to reduce the fleet and to improve the customer`s attendance. After the assembly of the configurations, and considering various scenarios of evolution of demand and increase of traffic congestion, analyses are made to examine the variations of the logistics costs. The thesis goes to showing that the increase in the costs of an additional advanced warehouse, can be paid with operational and marketing profits. The consideration of future scenarios with larger fuel costs and more dramatic traffic congestion shall reinforce the proposal of one warehouse but yet do not recommend the proliferation of them.
