Study on the distance entropy model based on three-parameter interval grey numbers and its application

Decision-making with interval grey number is an important research field in uncertain decision-making theory. For the decision-making problem with three-parameter interval grey number,this paper establishes an entropy model of three-parameter interval grey number distance based on information entropy theory,and proves the relationship of three-parameter interval grey number and grey distance entropy. On this basis,weighted method of multiple attribute decision-making with three-parameter interval grey number is put forward. Finally,the applicability of the method is verified by an example.
