Fuzzy multiattribute decision-making models and methods with incomplete preference information

There exist many efficient methods far fuzzy multiattribute decision-making problems with the decision maker's preference information completely known and completely unknown, while there is no research in fuzzy multiattribute decision makings with the decision maker's preference information incomple tely known. In this paper, such problems were studied. The average weighted programming and minimum average weighted deviation methods were establishe d A real example demonstrated feasibility and effectiveness of the methods proposed in this paper.
