【摘要】 项目数据来源多,管理复杂,数据模型的研究有助于简化项目管理系统的分析和设计。为了清晰表达项目数据模型,采用了本体论方法,提出了面向项目管理域的数据概念和关系的表达模式,并介绍了项目管理相关的主要概念;探讨了数据模型的共享域、专有域的划分以及信息的共享方式;分析了项目组织、任务组织、人员组织的数据模型框架,并阐述了主要的概念间关系;最后在数据模型的统一概念基础上,给出了数据模型的应用方式。更多还原

【Abstract】 Due to myriad source and complex management for project data, it is helpful to simplify the analysis and design of project management system by research of data model. Ontology is applied for expressing project data model clearly. The expression models of concept and relation in the domain of project management are presented, and main concepts related to project management are intro- duced. The public domain and private domain were discussed for sharing project information. The framework including project structure, task structure and personnel structure were analyzed by explaining important relationship, Finally, based on the uniform concept model of data model, the application mode is provided.更多还原
