Abstract:

This article proposes the definition of relative superiority degree between three parameters interval grey number and the real numbers, and two types of algebraic expressions are given. Based on the relative superiority degree, the ranking steps of three parameters interval grey numbers are set up and used in data envelopment analysis （DEA）model when the inputs and outputs are three parameters interval grey numbers, and a numerical example is given to illustrate its effectiveness.
