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...
Based on credibility theory, this paper presents a new class of fuzzy expected value model for data envelopment analysis (FEVM-DEA). In some special cases, such as the fuzzy inputs and fuzzy outputs are independent trapezoidal fuzzy variables, we transform the FEVM-DEA to its crisp equivalent class and discuss some basic properties of the proposed FEVM-DEA. Finally, a numerical example is given to...
