Abstract: The problems of model's low reusability and lacking management arc presented in the conceptual model's development of simulation system. To solve the above problems, the concept of meta conceptual model(MCM) was presented for realizing the conceptual model's abstract in the higher arrangement. The ontology conception was introduced to the MCM's designing, and the modeling method of ontology-based MCM(OMCM) was presented. The OMCM's hiberarchy and modeling method were given too. I3y mapping the OMCM to conceptual model, the conceptual model's modeling was realized. Finally,the method was applied in the conceptual model's modeling of equipment support simulation system, and the better validation was obtained.

Key words: Ontology, Meta-model, Conceptual modeling, Unified modeling language(UML)
