基于GFScom的多层次模糊综合评判与推理及其应用

Multi-layer Fuzzy Comprehensive Evaluation and Fuzzy Reasoning Based on GFScom and Their Application

根据GFScom的数学思想,提出了多层次的模糊综合评判与模糊推理方法,并将其应用在学生素质模糊评价系统的设计上。在阐述了具体设计思想后,与以往结果作了比较、分析。通过设计过程可以看出,所提出的设计方法不仅有效地模拟了领域专家根据人的感官获得不确定信息而进行推理综合评判过程,而且解决了以往设计方法在建立模糊关系矩阵时由人主观给出所带来的缺陷。

On the basis of GFScom （Generalized Fuzzy Sets with Contradictory, Opposite and Medium negation）, we present multi-layer fuzzy comprehensive evaluation and fuzzy reasoning approach, and apply them to the design of students ability fuzzy evaluation system. After the concrete idea of the system is depicted, the comparison and analysis between the existing outcome and method proposed by this paper are made. The design procedure of this system shows that the proposed method not only could simulate the comprehensive evaluation procedure carried out by domain experts according to the acquired undetermined information from human senses, but also solve the former shortcoming that the people subjectively give the fuzzy relationship matrix in the design of this system.
