Abstract :
Two problems in multi-attribute group decision process are studied: integration of multi-types of preference information and making use of given decisions. And a GDSS model based on rough set is proposed, which includes seven common ways for representing preference information. An improved Sem Naive Scaler Algorithm is also suggested to decentralize the information in the rough set table. Finally, rules based on dominance-based rough set theory are applied to the information table to rank all the alternatives.
