摘　　要：Ｒｏｕｇｈ集理论是一种具有模糊边界的集合理论．它被广泛应用于不相容决策表中的规则提取．本文讨论了基于多元组Ｒｏｕｇｈ集的不相容决策方法，并给出了相应的算法，同时也对不相容规则的相容度作了分析．该方法比普通Ｒｏｕｇｈ集方法更简单、更有效．Rough set as a theory of set with fuzzy boundary is widely applied to infer rules from an inconsistent decision table. This paper presents a new approach and its implementation algorithm to problems from the field of inconsistent decision making. It is based on multi tuple rough set, a generalized form of original rough set. We also provide a method to derive decision rules and tell how inconsistent rules can be used. It is shown that the new method is simpler and more effective than the ordinary one. The algorithm given in the paper is accustomed to the decision table which has duplicated tuples.
