成本偏差

研究结论：挣值法可运用于土地开发整理工程成本偏差分析。

The paper concludes that earned value method can be applied in the analysis of the total cost variance in land development and consolidation projects .

只有同质才能比较，因此把偏差e（t）细化成生产时间偏差和生产成本偏差等，并给出了计算方法。

It can be compared one variance with the other only they are homogeneous , so the deviation e ( t ) was subdivided into the deviation of production time and the deviation of production cost etc. The calculation methods of the deviation e ( t ) was represented .

世界银行采用购买力平价法来矫正劳动力成本偏差。AlbertKeidel表示，根据购买力平价法中国的国内生产总值约为美国的一半左右。

Based on the purchasing power parity ( PPP ) measure used by the World Bank to correct low labor-cost distortions , Albert Keidel said China 's GDP is roughly half of that of the United States .

项目施工成本偏差的控制

Control of Cost Deviation in Project Construction

并通过对成本偏差和成本变率，对每一道工序进行成本和进度的控制，实现工程总目标成本与进度要求。

Through the compute of cost deviation and cost variant rate , one can control both cost and schedule of every activity , then the total target cost and schedule of project can be controled .

同时，作者应用灰色数列预测理论建立起成本／进度偏差预测GM（1，1）模型，加强了赢得值控制方法的预测功能，更好地实现成本／进度的主动控制。

To make the control more dynamic , the writer establishes a costs and schedule forecast model based on the Grey Dynamic Model GM ( 1,1 ) to enhance the approach 's forecasting function .

从项目节制的角度而言，项目经理当对那些和预算成本有重大偏差的项次给予特殊的关注。

For project control , managers would focus particular attention on items indicating substantial deviation from budgeted amounts .

激励相容、交易成本与政策运行偏差

Incentive Compatibility , Transaction Cost and the Policy Running Deviation

该方法能改进传统挣值法在预测工期、成本方面产生的偏差，并且与传统挣值方法相比，增加了更多的原因分析信息。

It corrects the deviation derived from traditional earned value method when forecasting the duration and cost , and it supplies more analysis information than traditional earned value method .

但由于对养老保险转轨成本认识上的偏差，对养老保险转轨成本数量的测算相差悬殊，以至于不能作为科学决策的依据。

But because of understanding up of deviation to the transformation cost , Estimated quantity of the transformation cost differ extremely , with as for it can 't be the basis of science decision .

另外，如何能够在项目的发起阶段就能够有效的估算项目的整体成本并有效控制成本偏差，对于使用模型项目的实施成本的估算还需要进一步进行讨论及思考。

In addition , how can the project start-up phase on the project can effectively estimate the overall cost and cost-effective control of partial difference , the use of model for the implementation of the project costing estimate also need to further discuss and consider .

在评标阶段，本文主要研究一种考虑建设成本、时间成本、绩效偏差值和奖惩金额的方法。

At the phrase of tender assessment , this paper focus on a method which are considering costs of construction , costs of time , deviation of goal and real performance , award and fine .

在成本挣值法分析中引入目标成本这个基本参数，并增加目标偏差这个指标，使得施工项目目标成本偏差分析更加清晰。

Earned Value in the cost analysis of target cost of the basic parameters , is to increase the target deviation of the index , making the cost of deviation of the construction project objectives more clearly .
