Addition of rational fuzzy quantities: Convolutive approach. (English) Zbl 0668.94024

The addition of fuzzy quantities with rational values is defined by means of the convolution of their membership functions. It is shown that the rational fuzzy quantities with such operation form a group up to certain equivalence relation of very natural type.
