Fuzzy Super-Efficiency DEA Model and Its Application: Based on Fuzzy Structured Element

The super-efficiency DEA model resolves the ranking problem effectively, which is received much concern. The super-efficiency DEA model is built in this paper, in which inputs and outputs are both fuzzy numbers. The fuzzy super-efficiency DEA model is turned into a classical super-efficiency DEA model according to the structured element-based weighted ordering rules, expanded the scope of use of super-efficiency DEA model. Finally, an example is given to illustrate it.
