Abstract: The concepts of N-projective modules relative to a fully invariant submodule F of module N and R-projective modules relative to an ideal I are introduced.Basic properties of these modules are studied, some conclusions of N-projective modules,τ-N-projective modulesand Rad-N-projective modules are unified.

Key words: N-projective modules relative to a fully invariant submodule F of module N, R-projective modules relative to an ideal I, semisimple modules
