Abstract: Multiple attribute decision making theories based on Vague set are reviewed and introduced. Concerning of the shortcomings of existing research methods, a multi-stage fuzzy multiple attribute decision making method based on Vague set is proposed. Basic steps and implementation processes of the method are detailedly presented. Through multi-stage filtering of decision programs, the best decision is gotten, and the method effectively overcomes the common seen failure problem of various Vague set sorting functions. Numerical experiment shows that the method has good solving ability, and it provides a new way to solve fuzzy multiple attribute decision making problems based on Vague set.

Key words: Vague set, multi-stage, fuzzy multiple attribute decision making, sorting function
