‎In the thesis‎ , ‎we define the notion of a state BCK-algebra and a state-morphism BCK-algebra‎. ‎we present relation between state operators and state‎ -‎morphism operators and relation between mesure and states on BCK-algebras‎. ‎We study subdirectly irreducible state(morphism) BCK-algebra‎. ‎We introduce the concept of an adjoint pair in BCK-algebra and show there is a one-to-one correspondence between adjoint pairs and state morphism oprators‎.
