The aim of this paper is to solve the network cost efficiency with fuzzy cost using credibility approach. Precise measurement of data in the real world is not possible. Thus, considering precise data may not be true assumption in solving problem. One of the ways to deal with imprecise data is fuzzy data. We utilize meaning credibility measure, α- optimistic and α-pessimistic values to solve fuzzy network cost efficiency. When the confidence levels are known and data are triangular fuzzy numbers, using this method, the proposed model is transformed to a crisp model.
