Study on the Dynamic Information Model for Civil Engineering Project Management Based on Data Grid Technology

The civil engineering project management can be regarded as a huge information system. All information existing during the project management process of the total lifecycle should be integrated in this system. The information variety during the project total lifecycle and they exist in different computer and different place. Considering the character of project management information, the article presents the dynamic information model for project management based on data grid technology. The information are classified and the information model expressed by mathematic formula and three-dimension graph that described the information and their relationship each other. At the different phase of project management of the total lifecycle, the share and discovery of project management information are researched with data grid technology. The information resources which are distributed geographically or different structure are integrated.
