Wang Zheng-xin

Open publisher page 11 citations

Abstract

In order to solve the problem as to how to determine the index weight in Topsis,this paper puts forward an index of weights determination method based on grey correlation method,then combines this method with Topsis to construct a weighted Topsis model by grey incidence degree,and provides the calculation steps of weighted Topsis model.The effectiveness of this method is finally proved by example of supplier selection.
