Considering the following project data in the table. Assuming that in the baseline schedule every activity stars at the early start time (critical path method). The actual progress and cost are recorded at the end of 15^th week.

activity	Duration(week)	cost	completed	Actual cost	successors
1	0	0	0	0	2,3,4
2	6	120	100%	160	9,10
3	4	76	100%	70	5,6,7
4	3	30	100%	46	8,11
5	1	46	100%	76	10
6	6	150	100%	180	12
7	8	230	80%	220	8,11
8	5	186	10%	40	13
9	10	160	75%	180	14
10	12	320	40%	100	12
11	6	248	0	0	12
12	5	137	0	0	13

Give the planned value of the project.(Requirement: give the cost of every week during the project planned duration, and plot the accrued planned value)

According to the actual progress and cost data, calculate the SV, SPI, CV, CPI , and explain the meaning of these indicators.

According to the actual progress data, calculate the ES, SV(t), SPI(t), and explain the meaning of these indicators.
