In this article a methodology to resolve the problem of optimal location of reclosers and fuses in power electric distribution systems is presented, to improve reliability indices associated to the periodicity of the transient and permanent failures in the distribution systems. To formulate the problem, two non-linear binary mathematical models are posed that consider the location of reclosers and fuses under two scenarios of coordination, denominated "fuse save scheme" and "fuse blow scheme". The first model minimizes SAIFI index, and the second model minimizes MAIFI index. The set of constraints is the same for both models, which considers technical and operative characteristics. As solution strategy a methodology is proposed, which considers two different schemes of solution: the first scheme uses the commercial optimizer GAMS and the second scheme uses as solution technique a Chu & Beasley genetic algorithm (CBGA). In order to verify the validity of both strategies, these are executed in two tests systems from the specialized literature, comparing the results obtained.
