The most common forecasting techniques are some variation of: 最常用的成本控制估算公式有以下几种： EAC=Actuals to date plus a new estimate for all the remaining work. 完工估算等于目前实际成本与新剩余工作估算之和。EAC=AC+ETC ETC estimate to completion (目前)至完工估算This approach is most often used when past performance shows that the original estimating assumptions were fundamentally flawed, or that they are no longer relevant to a change in conditions.本公式适用于过去的项目执行情况显示最初的估算值从根本上已无效或者是与目前执行的更改无关的情况下。 EAC=Actuals to date plus remaining budget (BAC-EV). 完工估算等于目前实际成本与原剩余工作估算之和。EAC=AC+(BAC-EV) BAC=budget at completion 总预算This approach is most often used when current variance are seen as atypical and the project management team expectations are that similar variances will not occur in the future.本公式适用于目前的变更是非典型的，项目管理团队预测今后此类似的变更将不再发生的情况下。 EAC=Actuals to date plus the remaining project budget (BAC-EV) modified by a performance factor, often the cumulate cost performance index (CPI). 完工估算等于目前实际成本与原剩余工作估算变值之和。EAC=AC+(BAC-EV)/CPIThis approach is most often used when current variances are seen as typical of future variances.本公式适用于目前的变更在将来的变更中是典型的。
