المعادلات الواجب معرفتها قبل الامتحان:
FV =PV ( 1 + i) n
FV future value
PV present value
i interest per year
n number of years
========================
Risk score = Risk P * Risk I
Risk P risk probability
Risk I risk impact
========================
PERT Formula
EV=( O + P + ( 4* M )) / 6
EV expected value
O optimistic value
P pessimistic value
M most known value
SC = ( P - O ) / 6
SC Standard Confident
ONE TIME
EV +(1*SC)
EV -(1*SC)
TWO TIME
EV +(2*SC)
EV -(2*SC)
THREE TIME
EV +(3*SC)
EV -(3*SC)
========================
Number of communication lines = ( N *( N-1 ))/2
N nodes (participants)
=========================
Performance reports formulas
CV = EV-AC
CV cost variance
EV earned value = budgeted cost of work preformed (BCWP)
AC actual cost = actual cost of work preformed (ACWP)
SV = EV – PV
SV schedule variance
PV planned value = budgeted cost of work scheduled (BCWS)
CPI = EV / AC
CPI cost performance index
SPI = EV / PV
SPI schedule performance index
EAC 3 FORMULAS
EAC = AC + ETC
EAC estimated at completion
ETC estimated to completion
EAC = (AC +BAC) – EV
BAC budgeted at completion
EAC = (AC + (BAC – EV )+ CPI)
VAC = BAC – EAC
VAC variance at completion
ETC = EAC - AC
ETC estimated to completion __________________
