通过对实现工程管理信息化过程中各利益相关者的分析，提出了建立工程管理信息化的可参考途径，并对工程管理信息化架构的演变过程及相应模式进行了分析，提出了由服务层(service layer)、应用层(application layer)、资源层(resource layer)和基础设施层(infrastructure layer)构成的4层SARI架构。

This paper proposes a reference approach to the establishment of Engineering Management Informatization (EMI) through the analysis of various stakeholders involved in the implementation process. It also brings up the 4-Layer architecture (SARI) which consists of Service Layer, Application Layer, Resource Layer and Infrastructure Layer by the analysis of the process of evolution and the corresponding model of EMI architecture. This paper describes the content of SARI and its application to EMI.SARI is a common architecture with the characteristics of integrated system application, centralized data storage, unified IP-based networks, completed security mechanism and efficient intelligent management, achieves facilities sharing, data sharing, applications integration and services unification which provides a reference for the implementation of EMI.
