  7. Abstract:
  8. In electrification networks, a considerable percentage of electrical energy generated in power plant is dissipated through the path from generation to consumption, most of which is in electric power distribution, approximately 18%. The amount of these losses depends on several factors such as distribution networks structure, kind of apparatus, load density, kind of consumption, consumption curve, climatic conditions, due to diversity and variety of these factors, power losses differ even for two apparently similar electric power distribution . Power distribution companies in Iran decrease power losses since a few years ago, but in practice, because of different parameters and indexes, which sometimes have reverse effect on each others, so they have not reached positive results yet. Therefore managers and experts working in power distribution industry are facing problems in planning and decision making in this dissertation, according to data from electric power distribution under coverage of Iranian electric power distribution companies. Thereafter, first electric power distribution indices are compared with each other in a single – criterion and then in a multi criteria way using radar chart and power losses are analyzed. In the next step, by using QFD(Quality Function Deployment) technique and AHP(Analiytical Hierarchy Process) method, the requisitions of experts in power electric industry for decreasing electrical energy losses , are weightened and then are presented in general as well as in detail
