摘要
传统挣值法主要适用于工程量清单合同条件下施工单位项目管理活动。以传统挣值法为基础,以解决挣值法的基本方法与EPC总包项目的适应性和实现其在EPC总包项目中正确应用为目的,改进挣值(EV)的计算方法,引入新参数"产出计划值(OPV)",以解决挣值法与EPC总包项目的适应性问题,并将成本偏差分解为由于工程量变化引起的成本偏差CV(Q)和由于价格变化引起的成本偏差CV(P),便于准确揭示成本变化的具体原因,进而采取针对性的偏差控制措施。对同一案例分别用传统方法和改进后的方法进行分析,结果表明改进后的指标体系能更准确的反映EPC总包项目成本、进度状态和控制效果。
The traditional Earned Value Method （ EVM ） is mostly used at the condition of BOQ. Based on traditional EVM, to resolve the compatible between the traditional EVM and the EPC project, and realize the actual use in the EPC project. The calculation method of EVM is improved through introducing the new parameter OPV（Output Planned Value ）, resolved the compatibility between the traditional EVM and the EPC project, and separate the Cost Variance（ CV ） into two aspects： the CV caused by the Quantities（ CV（ Q ） ） and the CV caused by the Price （ CV（ P ） ）, so we can analysis the specific reasons of the CV, and then take targeted deviation control measures. Contrast with traditional method, the results show that the improved index system is more accurately reflect the EPC project cost, schedule status and control effect.
