چکیده:

Assume that we have DMUs each consuming inputs and producing outputs. Let be a -matrix and be a -matrix consisting of positive elements, containing observed input and output measures for the DMUs, respectively. We denote by and the amounts of inputs and outputs of DMUo, which is evaluated. In order to use more generalized model we extend the GDEA model in which the proposed model can project a DMU under evaluation along any feasible direction such as .
