基于网格的复杂项目信息系统研究

基于复杂项目固有的复杂性特征,分析复杂项目的信息管理需求和现有项目信息系统的不足,结合网格技术的特点,探讨复杂项目网格的可行性。在分析复杂项目网格运行机制的基础上,基于开放网格服务体系架构(OGSA),构建包括资源层、网格中间件层、应用服务层和网格门户层的复杂项目信息系统,阐述了各个层次的主要功能。基于OGSA的复杂项目信息系统实现了复杂项目管理的信息化、远程化和协同化,为有效管理复杂项目提供一个全新的技术支持方案。

Study on Grid-based Complex Project Information System

Based on inherent complexity features of complex projects,it explains the information management need of the complex project. And deficiencies of the current project information system are analyzed. According to the characteristics of grid,it studies feasibility of complex project grid. After analyzing operation mechanism of the complex project grid,a complex project information system based on OGSA has been designed,which contains resource layer,grid middleware layer,application service layer and portal layer. It then explains the main functions of each level. Grid-based complex project information system provides an approach to manage complex project in a intelligent,remote and collaborative model.
