联合分析是一种从总评估中得出每个因素的部分价值的方法。这也可以应用于多准则排序或选择问题。它通常是在联合分析中，假设值函数被预定义为可加和传递模型。然而，存在许多情况，其中预定义的值函数不适合于真实的情况。在这项研究中，我们提出了基于粗糙集近似的优势关系的联合分析。在我们的配方中，定性数据经常使用的常规方法转化为有序值的优势关系，使用区间回归分析。在我们提出的方法中，联合分析中的偏好结构可以用if-then规则来表示，而比信息系统中的因素组合更好的因素组合可以通过偏序关系来找到。© 2004 Wiley Periodicals，Inc.
Conjoint analysis is a method for deriving the part‐worth value of each factor from the total evaluations. This also can be applied to multicriteria ranking or choice problems. It is generally in conjoint analysis, assumed that the value function is predefined as the additive and transitive model. However, there exist many cases in which the predefined value function is not appropriate to real situations. In this study, we propose conjoint analysis based on rough sets approximated by dominance relations. In our formulation, qualitative data often used in the conventional method are transformed into ordered values by dominance relations using interval regression analysis. In our proposed approach, preference structure in conjoint analysis can be represented by if‐then rules and better combinations of factors than ones derived from the information system can be found by partial order relations. © 2004 Wiley Periodicals, Inc.
