Abstract :

Today, it is very important to evaluate companies and organizations that have a multi-level network structure. In the aviation industry, paying attention to the multi-stage structure can be very important due to the importance of the visa at each stage and preventing accidents and unpleasant events. In this article, based on the fuzzy probability function approach, a two-stage network model is proposed in data envelopment analysis. First, the efficiency calculation models in the first and second stage of the fuzzy network are proposed and we use the probability function approach to de-phase the models, then the comparison of the efficiency of the first stage, the second stage and the overall stage is presented based on the two-stage network model, and in The completion of the comparison of efficiencies based on alpha-cuts in the fuzzy network of 16 Iranian airlines is investigated. At the end of the study, an application with fuzzy tens is presented.
