项目费用控制的一个有效手段

获得值是项目费用控制和项目进度控制的重要度量指标.本文论述了获得值的概念和方法,介绍了它在项目控制中的重要作用,以及应用获得值预测项目完工时可能的费用.然后,介绍了S曲线,S曲线可以显示在当前时间项目的费用是否超支,以及进度是提前还是滞后于计划.最后,描述了基线与预算的区别和联系.基线是控制的尺度,预算则是业主最期望花费的费用,二者的差值就是不可预见费. 

Effective Measurement in Project Cost and Schedule Control

Earned Value is the most important measurement in the project cost and schedule control. This paper describes the concept and methods of earned value,and its application in the project cost and schedule control. Then, this paper tells how to forecast the likely cost to complete the project,and intruduces the concept of S curve. Using S curve, it's easy to present that whether the project is under or overspent as it progress, and if the project is ahead or behind schedule. At last,this paper describes the difference between the baseline complete cost and the budget. The baseline complete cost is one of the measurement of project control, while the budget is the expected cost which the owner of the project wants to pay. The difference between the two is the contingency.
