In order to make decision more efficiently, this paper proposes fuzzy decision making method based on Vague soft relation. The Vague soft relation is defined, then the relation table is contructed using the Vague soft relation, moreover, all alternatives are ranked using a new score function and the best one is selected. An example is given to demonstrate the effectiveness and feasibility of the proposed method.
