Intuitionistic Fuzzy Differences: Robustness and Duality Analysis
R. Zanotelli, R. Reiser, A. Yamin and B. Bedregal

This paper extends the robustness analysis of the fuzzy connectives based on the pointwise sensitivity of such operators. Starting with an evaluation of the δ sensitivity in representable fuzzy negations, triangular norms and conorms, we apply the results in the class of fuzzy difference operators and their dual construction. The paper formally states that the robustness preserves the projection functions related to intuitionistic fuzzy (co)difference operators.

Keywords: Atanassov’s intuitionistic fuzzy logic, δ sensitivity, robustness, fuzzy (co)difference operators
