1. Third, carry out standard cost control and analyses cost variation.

2. Secondly, carry out standard cost control and analyses cost variation.

3. Based on SS curves, new parameters of cost variation (CV) and schedule variation (SV) were proposed to realize the monitoring of project performance.

4. With the PCs for example, the sensitivity analysis is carried out on account of the benefit or cost variation.

5. In chapter 3 , the author discusses cost analysis methods , with the intention to find the factor affecting cost variation and define the affecting degree .
