| Abstract: | In this paper, the DEA approach to decision making units with a kind of special input and output, named LR-type fuzzy number,has been researched. This thesis defines the order relation between these two numbers and then builds a confidence DEA model. In contrast to general DEA model, this model can be easily applied and enhance the reliability of evaluation with the enough consideration about the characteristics of LR-type fuzzy number. |
