You cannot escape knowledge points gained in first level civil engineer test. For first-time test takers, it takes a long time to remember and it is not easy to remember. Today I will take everyone to summarize this point of knowledge together!
1. Three commissions
2. Three cost calculations
3. Four evaluation indicators
4. Calculation of four evaluation indicators
5. Evaluation of the four evaluation indicators
The Earned Value Estimation Index is really designed to evaluate whether a project is making money or losing money at a given point in time, and whether it is faster or slower. Making money (loss of money) = income - expense; progress rate = completed work - planned work;
6. Remember formula
Head already? Too easy to confuse. English letters in forward and reverse order.
Remember a few letters:
A=Fact; B=Budget; C=Cost; S=Schedule; P=Completed
Look at BCWP, ACWP, BCWS, it's simple;
For four evaluation proposals, just remember C; if there is a C, it is a cost related indicator and rest are progress indicators;
Look again at CV, CPI, SV, SPI. Everything is very simple?
Who subtracts from four assessments, who eliminates, who again feels dizzy.
It's okay, just remember formula:
For a bowl of fish, progress comes first, then price; if more, then good.
1. Bowl of fish = completed work budget
2. No matter which index is calculated, it has a bowl of fish in front of it;
3. Calculate progress indicators and replace previous "fish bowl" parameters;
4. Calculate cost index and replace parameters behind "cup of fish";
5. "Done" and "Planned", "Budget" and "Actual"
6. For result of calculation, if it is greater than 0 or 1, this is a good phenomenon, for progress, it is ahead of schedule, and for cost, it is a savings.
Third, expressive method of variance analysis
Different expression methods can be used to analyze variances: histogram method, table method, and curve method.
