Safety Model Analysis and Design of Project Cost Control System

在综合分析工程项目投资控制需求和特点的基础上 ,结合信息处理技术的基本理论 ,对工程项目投资控制信息系统的安全性能进行了深入的分析和探讨 ,提出了信息系统的安全性模型 ,并在系统设计中得到了较好的应用 .

The safety and secrecy of the data and system is an important and difficult field in design and development of the Project Cost Control System(PCCS).There is no solution now.Based on the theory of Project Cost Control and Information Technology,the paper discusses and analyses deeply the safety and secrecy of the data and system of the PCCS,and puts forward the safety and secrecy model PCCS which is well used in the system.
