信息系统的应用实现了对公路建设过程全程动态管理和实时监控,有效实施对建设项目的“四大控制”(质量、费用、进度、安全)和“两大管理”(合同、信息)。文章通过分析全寿命周期的项目集成管理、PDCA循环管理模式、挣值原理,阐述了信息化技术如何在公路项目建设管理过程发挥作用。 The application of information system realizes the dynamic management and real-time monitoring of the entire process of highway construction and effectively implements the management of the “four major control” (quality, expense, schedule, safety) and “two management” information). By analyzing project life cycle integrated management, PDCA cycle management model and earned value principle, the paper expounds how information technology can play a role in highway project construction and management process.
