As the partner selection is crucial to the establishment of virtual enterprises,a multi-attribute group decision-making model is proposed based on the thought of similarity to ideal solution（TOPSIS）,which takes the attribute values as the interval number.In this model,according to the individual weight of each decision maker for each attribute,the closeness of each candidate enterprise to the individual ideal point of each decision maker is obtained.Then,according to the authorities of all decision makers,the closeness of each candidate to the group ideal point is computed,by which a right order of candidate enterprises can be acquired.The rationality and feasibility of the proposed method is verified by a numerical example in the end.
