Two classes of fuzzy linear regression models are considered, one involves real design points and fuzzy number parameters, the other consists of fuzzy number observations and real parameters.

考虑两类模糊回归模型：一类是设计点为实数、参数为模糊数；另一类是观察值为模糊数、参数为实数。

In this paper, by redefining the order relation for fuzzy Numbers and zero fuzzy number, we obtain that the operation properties of fuzzy Numbers are more similar to real Numbers.

通过对零模糊数以及模糊数的序关系的重新定义，使得模糊数与实数有了更相似的运算性质。
