Here in this paper, we provide characterizations of fuzzy quasi-ideal in terms of level and strong level subsets. Along with it, we provide expression for the generated fuzzy quasi-ideal generated by level subsets and strong level subsets of the given fuzzy set in explicit manner. We also establish the existence for a generated fuzzy quasi-ideal in ternary semigroup by showing that the non-empty intersection of an arbitrary family of fuzzy quasi-ideals is again a fuzzy quasi-ideal. This paper introduces and explores the concept of generated fuzzy quasi-ideals in ternary semigroups, extending classical algebraic notions into the fuzzy domain. A fuzzy quasi-ideal is defined as a fuzzy set that satisfies specific conditions analogous to those of crisp quasi-ideals under the ternary operation. A foundational result established in this work is that the non-empty intersection of any family of fuzzy quasi-ideals in a ternary semigroup remains a fuzzy quasi-ideal, reinforcing the internal consistency of the structure. Furthermore, we explore key properties of these generated fuzzy quasi-ideals, including their relationships with level sets and strong level subsets. The central focus of the paper is on how fuzzy quasi-ideals can be generated by arbitrary fuzzy sets within a ternary semigroup. We establish methods for constructing the smallest fuzzy quasi-ideal containing a given fuzzy set, along with expressions for this generated structure in terms of the quasi-ideals generated by its level and strong level subsets. Through constructive proofs, we demonstrate the existence by showing the non-empty intersection of an arbitrary family of fuzzy quasi-ideals in a ternary semigroup is itself a fuzzy quasi-ideal and uniqueness of such generated fuzzy quasi-ideals. The findings contribute to a deeper understanding of the internal structure of ternary semigroups and provide a foundational framework for further research in fuzzy algebraic systems. In summary, this work establishes a comprehensive framework for generated fuzzy quasi-ideals in ternary semigroups, revealing their structural properties, generation mechanisms, and theoretical importance. These results contribute meaningfully to the study of fuzzy algebraic systems and open new avenues for further research in fuzzy ternary algebra.
