摘要:

定义了三参数区间灰数与实数比较的相对优势度的概念,给出了两类典型的三参数区间灰数与实数比较的相对优势度的代数表达式。提出了一种基于相对优势度的三参数区间灰数的排序方法,并应用于变量为三参数区间灰数数据包络分析(data envelopment analysis,DEA)模型,用算例验证了其有效性。

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.
