摘要 利用模糊数的绝对值定义了模糊有界变差函数 ,给出了模糊有界变差函数的刻划定理 ,讨论了模糊有界变差函数的可导性 . With the concept of absolute value for the fuzzy-numbers, the fuzzy-valued function of bounded variation is defined and characterized. Next, the differentiability of fuzzy-valued functions of bounded variation is discussed. Moreover, the proof of the differentiability of fuzzy-valued functions of bounded variation is constructive.
