基于结构元理论定义了LR型模糊数乘法的一种近似计算和模糊数之间的距离.针对全模糊线性回归模型,利用LR型模糊数乘法的近似计算和定义的距离给出该模型的最小二乘近似解.
A kind of approximate multiplication of L-R fuzzy numbers and a distance between them are defined in this paper based on structured element theory.According to fully fuzzy linear regression model,a method is presented to evaluate the fuzzy least squares by use of approximate multiplication of L-R fuzzy numbers and a distance between them.
