建立了对工程变更信息进行描述和存储的统一信息模型，在此基础上设计了变更视图提取和变更关联操作算法。为保证变更信息在系统间传递的准确与一致，基于XML Schema定义了中性化变更视图对象文档，并提出了针对变更视图的服务化映射机制。建立了基于流程推送与服务请求推拉结合的变更流程控制模式。通过具体实例验证了所构建的统一模型和流程控制机制，为变更信息管理提供了可选方案。
建立瞭對工程變更信息進行描述和存儲的統一信息模型，在此基礎上設計瞭變更視圖提取和變更關聯操作算法。為保證變更信息在繫統間傳遞的準確與一緻，基于XML Schema定義瞭中性化變更視圖對象文檔，併提齣瞭針對變更視圖的服務化映射機製。建立瞭基于流程推送與服務請求推拉結閤的變更流程控製模式。通過具體實例驗證瞭所構建的統一模型和流程控製機製，為變更信息管理提供瞭可選方案。

A unified model for the description and storage of engineering change information was established.Then,the extraction method for change information view and correlation manipulation algorithm were proposed.In order to ensure the consistency and accuracy of engineering change infor-mation between different systems,the obj ect document of change information view was built based on XML Schema;meanwhile,the service-oriented obj ect mapping mechanism for change information view was established.The combined push-pull mechanism based on workflow and service-request was constructed.Finally,the unified model and control mechanism was verified with an instance.This re-search provides an alternative method for the management of engineering change information.
