Abstract

The data in traditional DEA model are limited to crisp inputs and outputs, which cannot be precisely obtained in many production processes or social activities. At the same time, the traditional DEA model can not evaluate by using some given reference units. This paper attempts to extend the traditional DEA model and establishes a fuzzy DEA model based on sample data evaluation. To establish this model, we provide the definition of the strong efficiency, general efficiency, α - possibilistic fuzzy efficiency and weak efficiency of fuzzy sample C²R model.
