摘要
本文在模糊σ-代数及模糊数的极大全序子集之上定义了模糊随机变量,进而首次定义了客观实用的模糊随机变量的概率分布函数,并讨论了数学期望及方差等数字特征。
In this paper we give the definition of fuzzy randon variable on the basis of fuzzy algebra and maximum total ordering subset,and first define its probabilistic distribution function wich is of objectivity and practicality. We also investigate expectation and variance of fuzzy random variable.
