Reliability is one of the important factors in the electricity networks studies by which the weak points of the network are identified. Appropriate strategies can be suggested for future planning and efficient utilization of the networks by the identification of the weak points. Considering that electrical distribution networks are among the most appropriate parts in reliability measurement studies, reliability scales for Zahedan Distribution Network in 2012 were calculated in the current work. In this study, input parameters were modelled by defining appropriate membership functions with the triangular fuzzy algorithm. Then, the appropriate criterion for calculation of reliability in distribution systems was selected using Analytic Hierarchy Process (AHP), and reliability of the input parameters were calculated based on the selected criterion. The purpose of these calculations is presentation of necessary strategies for planning to decrease the number and duration of unplanned power failures, decrease the losses, and propitiate electricity consumers in Sistan and Baluchestan Province. In this paper, the case study is based on the sample network of Zahedan.
