該文是針對訓練模擬器模型開發支持平臺——模型管理系統的研究，主要目的是解決
模型數據管理系統中更改管理問題。訓練模擬器開發是一個復雜系統工程，在開發過程中要產生大量的產品數據，該文通過基于本體的概念模型把這些大量的異構數據聯系起來，通過對概念模型之間語義距離計算，建立模型文檔之間的關系，從而為模型更改管理提供支持。

Abstract Purpose of this paper is to resolve model documents changes management, which is a part of model management system in a simulator-supported platform. It is a complex procedure to develop training simulators, which amount of structured and non-structured data will be product. To management these data as well as the procedure, it is needed to describe by using of conceptual model based xml/ontology metadata. And a method is proposed to relate model documents by conceptual model, which would be used for model changes management.
Keywords conceptual model, ontology, training simulator.
