摘　　要：模糊集FScom提出知识中的否定关系可分为矛盾否定关系、对立否定关系和中介否定关系。针对模糊集IFScom在处理多重λ-中介否定问题时会产生较大偏差,对其中介否定算子作了改进。改进的新模糊集IFScom*具有的性质更利于解决实际问题。在此基础上提出一种基于IFScom*的模糊综合评判方法,通过对地震自然灾害等级评判的应用,结果表明该方法是合理有效的。Fuzzy set FScom proposes that the negative relation in knowledge can be divided into three types： the contradictory negation, the opposite negation and the medium negation. In light of the problem that fuzzy set IFScom will introduce large error to handling multiple λ- medium negative, we improve the medium negation operator among them. The nature the improved new fuzzy set IFScom^＊ possesses is conducive to solving practical issues. On this basis, we propose an IFScom^＊-based fuzzy comprehensive evaluation method, by applying it in evaluating the grade of earthquake natural disaster, the results show that this method is reasonable and effective.
