Multiplication of fuzzy quantities. (English) Zbl 0786.04006

The arithmetic of fuzzy numbers is discussed in order to determine a multiplicative group of fuzzy numbers. Under rather restrictive assumptions there exists a multiplicative group of equivalence classes of fuzzy numbers. This result leads to a group of fuzzy powers of a given positive fuzzy number.
Another approach to the arithmetic of (convex) fuzzy numbers was presented by R. Goetschel and W. Voxman [Fuzzy Sets Syst. 18, 31-43 (1986; Zbl 0626.26014)].
