The fundamental concept of fuzzy sets was initiated by L. Zadeh [12] in 1965. In this project work, we introduce the concept of fuzzy PMS- ideals in PMS- algebras and we discussed about the definitions of PMS- algebra, PMS- ideal, sub algebra, Fuzzy set, upper level and lower level subset of µ, fuzzy PMS-ideal, fuzzy PMS-sub algebra and the t-level set and reproof their related properties.
