A multi-attribute group decision making method composed of intuitionistic fuzzy set and TOPSIS will be introduced into project material bidding procurement. First, the opinions of experts about bidders and indicators' attributes are expressed by linguistic terms, and then turned into intuitionistic fuzzy numbers, which can be used to obtain the weights of the indicators' attributes and experts. Based on the opinions of decision makers and IF WA operator, an aggregated intuitionistic fuzzy decision matrix is formulated. In the end, the bidders are ranked by TOPSIS method.
