Based on the traditional earned value method, the multi-level earned value analysis method are put forward, this method can predict the total cost and total duration more accurately, and then, it can timely find the deviation place of cost and schedule in project, so as to rectify the schedule plan and provide more scientific basis for the schedule and cost management of project.%传统挣值分析法评价和预测项目的总体执行情况,由于忽略了项目内部各个工作包之间的逻辑关系,从而容易导致项目进度的评价结果与实际执行情况相背离。本文在传统挣值法的基础上提出多级挣值分析法,该方法能更加准确的预测项目总成本和总工期,并且能及时找到项目成本和进度出现偏差的位置,从而及时纠正进度计划,为项目进度管理和成本控制提供更加科学的依据。
