Abstract: Universal average operation model can satisfy the requirement of logic compromise of continuous valued logic. But the existing universal average operation only discusses an ideal state that every factor is with equal weight Two kinds of weighted operators were given, and unectual weighted universal average operation model and its dual model were proposed. It is pointed out that weighted arithmetic average operator, weighted geometric average operator, wcigh- ted harmonic average operator, and general average operator with weight are special cases in dual model of unequal weighted universal average operation model. Finally, we compared similarities and differences between general average with weight and unequal weighted universal average operation model.

Key words: Universal logics, Unecaual weighted universal average operation model, General average with weight
