Abstract
We introduce ⊕ radical supplemented modules and strongly ⊕ radical supplemented modules briefly srs ⊕modules as proper generalizations of ⊕ supplemented modules We prove that 1 a semilocal ring R is left perfect if and only if every left Rmodule is an ⊕ radical supplemented module 2 a commutative ring R is an Artinian principal ideal ring if and only if every left Rmodule is an srs ⊕module 3 over a local Dedekind domain every ⊕ radical supplemented module is an srs ⊕module Moreover we completely determine the structure of these modules over local Dedekind domains
