The present work cxplains a model of optimization for primary nets of distribution, using the algorithm of linear programming code like Simplex for Graphs, Starting from this model, a program for calculation was developed to select the optimum routes of the primary feeders, with respect to the nodes and the arches the program takes it upon to elect given an initial graph that represents the possible interconnections between the nodes, by means of the arches and the capacity of these, and eliminates the unecessary arches in order to achieve the minimal cost of the losses and the investements. The system is a WINDOWS application, and has graphic instrument which permit to draw the net with M elements in the screen. This system was used in one distribution feeder of 107 nodes that belongs to Narajito Town (A-960) by Transmission and Distribution Company of Ha vans. The performance's time was one minute two seconds.
