In this paper, the notion of interval-valued
m
-polar fuzzy positive implicative ideals in BCK-algebras is presented. Then, the relationships between interval-valued
m
-polar fuzzy positive implicative ideals and interval-valued
m
-polar fuzzy ideals are investigated. After that, the concepts of interval-valued
