摘要：An equivalence relation is defined in the set of fuzzy numbers. In
a particular equivalence class, arithmetic operations of fuzzy
numbers are introduced. A fuzzy matrix with respect to a
particular class and its associated crisp matrices are also
introduced. The concept of equivalence class is applied in fuzzy
decision-making problems and justified through a numerical
example.
