設Fs為在實數軸上的模糊數和水準1的模糊區間。我們利用分解原理考慮在Fs 上的模糊冪級數。我們定義在冪級數f(X)上的模糊導數f'(X)，模糊積分f(X)和模糊定積分f(X)。我們也倒出一些模糊級數的性質。
Let Fs be a family of fuzzy numbers and level 1 fuzzy intervals on R=(-,). We use decomposition theory to consider the fuzzy power series on Fs. We will define the fuzzy derivative f'(X), the fuzzy integral f(X) and the fuzzy definite integral f(X) on the fuzzy power series f(X). We also derive some properties about the fuzzy series.
