Fuzzy relations on fuzzy and non-fuzzy numbers - fast computation formulas. (English) Zbl 0669.94027
Fast computation formulas for the operation \(\sup_{x,y}\min [h(x),z(y),\phi (x,y)]\) are proved, in case the membership functions h, z of fuzzy numbers and non-fuzzy numbers are “triangular”, “rectangular” and the \(\delta\)-function of Dirac.
