Abstract: LetS be a pomonoid. S-poset satisfying condition (E') is defined and weakly pullback flatness is given over pomonoid. Furthermore, the homological classifications of pomonoids by their Rees factor S-posets are investigated.

Key words: condition(E'), weakly pullback flat, Rees factor S-poset
