An intuitionistic fuzzy multiple attribute decision making method based on improved score function

In multi-attribute decision making, the risk p reference of decision maker can influence the decision result to a great extent. According to the characteristics of intuitionistic fuzzy numbers and the characteristics of multiattribute decision making, we introduced the risk preference factor, construct the intuitionistic fuzzy score function based on risk preference, and studied its properties and ranking rules. Combined with Choquet integral operator, we established an intuitionistic fuzzy multi-attribute decision making method based on risk preference, and applied it to a specific example. The results show that the method can well reflect the risk attitude of decision maker, and it is practical and effective.
