FUZZY SETS AND SYSTEMS, cilt.117, sa.3, ss.431-437, 2001 (SCI-Expanded)
In a different sense to Rosenfeld's approach (J. Math. Anal. Appl. 35 (1971) 512-517), considering the fuzziness on the group operation a new kind of group structure on a crisp set is introduced and some of its properties are presented based on the concept of fuzzy function.
