Abstract :
In order to determine the strengths and weaknesses of the management of operation and maintenance of irrigation and drainage networks of Daryun 1 and 2, the mentioned network was examined using the classical evaluation method. For evaluation in the model, the indicators were divided into five windows: technical, service-management, environmental, social and economic. 66 required indicators of the model were identified. To weigh the indicators, a specialized questionnaire of pairwise comparisons of the index was designed and provided to the experts.According to the results of the questionnaires, 11 matrices were prepared for each section and then a matrix was prepared for each group. The internal numbers of the mentioned matrix were obtained from the geometric weight average of each 11 matrices.Finally, the weight of window indicator indices was calculated by special vector calculation method by Maple software, then the numerical value of different window indices was calculated using SAW model.Based on the results obtained from the model calculations, the environmental window with a score of 0.956 is in the first place and its evaluation is good. The evaluation of the network in social, service-managerial, technical fields with scores of 0.864, 0.853, 0.827 in the next categories, respectively It is located and evaluated as average and the network has the lowest rank in economic fields with a score of 0.768. In general, it can be said that the performance of Dariun irrigation and drainage network with a score of 0.853 is generally average.
