Abstract

An almost ideal in a semigroup is a generalization of the concept of an ideal initiated by Grosek and Stako in 1980. In 2019, S. Suebsung et al. developed almost (m, n)-ideals in semigroups. Later, in 2021, T. Gaketem. introduced interval valued fuzzy almost (m, n)-ideals in semigroups. This paper aims we define interval valued fuzzy ordered almost n-interior ideals ordered semigroups. We prove some basic properties of interval valued fuzzy ordered almost n-interior ideals in ordered semigroups. And, we investigate a bridge between almost n-interior ideals and interval valued fuzzy ordered almost n-interior ideals in ordered semigroups.
