Consider a project that requires the completion of 7 tasks, as follows:
o Tasks A and B can begin simultaneously at the beginning ("time zero").
o Task C can only begin after task B is completed.
o Task D can only begin after task A is completed.
o Task E can only begin after task A is completed.
o Task F can only begin after task E is completed.
o Task G can only begin after tasks C and D are completed.
The expected durations (in days) of each task are as follows: A=15; B=15; C=10; D=10; E=30; F=20; G=40.
What is the expected completion of the whole project?
A. 50 days
B. 60 days
C. 70 days
D. 75 days
Consider the project from the previous question with the added complexity that the actual completion time of each task will be:
A) 15+ RANDBETWEEN(-8,8)
B) 20+ RANDBETWEEN(-8,8)
C) 10+ RANDBETWEEN(-8,8)
D) 10+ RANDBETWEEN(-8,8)
E) 30+ RANDBETWEEN(-8,8)
F) 20+ RANDBETWEEN(-8,8)
G) 40+ RANDBETWEEN(-8,8)
Using PERT, what is the expected completion time of the project?
A. 50 days
B. 60 days
C. 70 days
D. 75 days

Answer :

Answer:

D. 75 days

F) 20+ RANDBETWEEN (-8,8)

B. 60 days

Explanation:

The project has 7 tasks which needs to be completed to finish the project. There are task a and b which can start simultaneously so we will start these two tasks together to reduce the time of the total completion of project. The projects a and b can start at zero = 15 days

using the following equation we calculate days to complete the project.

15ab + 10cde + 20ge + 20fg  = 75 days.
