Abstract :

Intuitionistic Fuzzy Sets are substantial extensions of fuzzy sets which play a key factor in describing and providing ease of solving higher complexities in engineering and science. However, certain ambiguous situations cannot be addressed by using fuzzy sets and intuitionistic fuzzy sets. The extension of fuzzy set, namely, Temporal Intuitionistic Fuzzy Sets paved the way for implementing methods and techniques for unanswered problems. In this study, we proposed certain level operators N?(A), N?(A) and N?,?(A) for temporal intuitionistic fuzzy sets and investigated some of their properties. We gave numerical examples for TIFS and also study the relations between temporal intuitionistic fuzzy sets of certain level.
