【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。更多还原

【Abstract】 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.更多还原
