基于区间模糊数的模糊线性回归模型及其应用

Research on Fuzzy Linear Regression Model and Its Application Based on Interval Fuzzy Number

以区间模糊数为研究对象建立了模糊线性回归模型,以模糊集之间的测度贴近度为理论依据引入了一种模糊数之间距离的概念,并通过最小二乘原理给出了该模型的参数估计方法,最后结合沈阳市温度变化情况的实际例子给出该模型的应用。

Based on interval fuzzy number, a kind of fuzzy linear regression model is established. And it introduces the notion of distance between fuzzy numbers taking similarity as theoretical basis. It gives the parameter estimation method by least-square principle. Combining with temperature change in Shenyang city, the application of this model is given.
