PROBLEM 1
Use the network diagram below and the additional information provided to answer the corresponding questions. [15 points]
a) Give the crash cost per day per activity. [10 points]
A = $125
B = $50
C = $250
D = $300
E = $250
b) Which activities should be crashed to meet a project deadline of 10 days at minimum cost? What is the cost impact of crashing these activities? [3 points]
E (by 1 day) and B (by 1 day). The cost impact of crashing these activities is $300.
c) Find the new budget (or cost of the project). [2 points] The new cost of the project would be $1750.
PROBLEM 2
Use the network diagram below and the additional information provided to answer the corresponding questions. [13 points] a) Give the crash cost per day per activity. [10 points]
A = $250
B = $50
C = $250
D = $100
b) Which activities should be crashed to meet a project deadline of 13 days at minimum cost? What is the cost impact of crashing these activities? [3 points]
Crash B by 1 day at a cost of $50.
PROBLEM 3 [8 points]

$540
$523
$535
a) Calculate the cost variance (CV). [2 points]
CV = EV-AC = $535 - $540 = -$5
b) Is the CV over or under budget? [2 points]
The CV is over budget.
c) Calculate the schedule variance (SV). [2 points]
SV = EV – PV = $535 - $523 = 12
d) Is the SV ahead of or behind schedule? [2 points]
The SV is ahead of schedule.
