The structures of upwards directed generalized effect algebras with Riesz decomposition property are studied.The definition of prime ideal in a generalized effect algebra is introduced.It is proved that an upwards directed generalized effect algebra with Riesz decomposition property is finitely subdirectly irreducible if and only if it is an antilattice.Then it is shown that a quotient of an upwards directed generalized effect algebra with Riesz decomposition property is an antilattice if and only if the ideal inducing that quotient is prime. At last, it is proved that every upwards directed generalized effect algebra with Riesz decomposition property has a subdirect product representation.
