The relative efficiency evaluation of DMUs in fuzzy environments is studied. First, the influences of fuzzy factors on the relative efficiency evaluation of DMUs are analyzed. Then, according to the cut set approach of fuzzy programming and the economic meaning of DEA, the fuzzy DEA model is solved. Finally, the definitions of fuzzy DEA efficiency of DMUs are given. The average confidence efficiency for comparison of DMUs is defined, too. There is an example of the use of fuzzy DEA in the end of the paper.
