Navigating Economic and Agricultural Realms with Interval-Valued Complex Neutrosophic Fuzzy Sets

This article introduces the concept of the interval-valued complex neutrosophic fuzzy set, which extends traditional neutrosophic sets to address challenges like uncertainty, inconsistency, and indeterminate information. This specialized set blends complex fuzzy functions and real-valued fuzzy terms with phase elements. This article also discusses Hamming and Euclidean distances and proposes similarity measures based on these distances. These measures are applied in a multi-criteria decision-making method within an intervalvalued complex neutrosophic fuzzy structure. Practical applications include ranking alternatives and identifying optimal choices. Illustrative examples demonstrate its effectiveness in handling interval-valued complex neutrosophic fuzzy sets.
