微格课程成绩评定与模糊关系方程的解

摘要

首先定义了模糊关系方程的e极小解,然后给出了利用模糊神经网络寻找max-min合成有限模糊关系方程的一个e极小解的算法,证明了算法的收敛性.最后把模糊关系方程的解应用于大学微格课程成绩的评定,并用算例进行了说明.%A method of student grade evaluation of micro-class is introduced in this paper.Firstly,the ε-minimal solution of a fuzzy relational equation is defined.Secondly,an algorithm is introduced in order to find one ε-minimal solution from the fuzzy relational equation by using fuzzy neural network and then to determine its convergence.Finally,the solution of fuzzy relational equation is applied to the student grade evaluation and a numerical example is illustrated.
