Abstract: n the process of implementing Enterprise Service Architecture（ESA） software，using enterprise reference model effectively can accelerate enterprise modeling rate，improve software’s implementing efficiency，and reduce the implementation cost greatly.How to get the proper reference model form the reference model database is an important problem of reference model management.In view of the shortcomings of present popular reference model classification and retrieval algorithms，a reference model classification and retrieval algorithm based on rough set theory was put forward.The reference model’s characteristics were analyzed，and the characteristics were divided into two types：Fuzzy characteristics and specific characteristics.After the fuzzy characteristics being discreted，the reference model’s characteristics were treated using rough set theory，then the reference model which has maximum similarity with the newly building model was selected.At last，the correctness and effectiveness of this algorithm was attested through a case.
