摘要：Conjoint analysis is a method for deriving the part worth value of each factor from the total evaluations. In conjoint analysis, it is generally assumed that the value function is pre-defined as the additive and transitive model. However, there exist many cases in which the pre-defined value function is not appropriate to real situations. In this paper, we propose conjoint analysis based on rough sets approximated by Dominance relations. In our method, preference structure in decision making problems can be represented by IF-Then rules and better combinations of factors than the given ones in the given information system can be found by partial order relations.
