A).
This wouldn’t work
. This is because you need to use “the Early Start Time Rule” which states
the ES time of an activity is equal to
the largest EF ti
mes of all
the activities that immediately
precede it. If you are taking a day away from task A it will result in shortening task C which will
not effect the end result since Task C is not the largest EF time of C, D and F.
This is Not the
correct answer
.
B). This would Work. Task B is connected to the largest EF time Task F and connected to the
critical path. This is
the correct answer
because It is the cheapest amount that would shorten
the overall length of this project by one day.
C). This woul
d Work
in shortening the task by one day
. Task
D
is connected to the largest EF
time Task F and connected to the critical path
and would shorten the overall length of this
project by one day
. This is
Not the
correct answer
because It is
more expensive th
an option B.
D). This would Work in shortening the task by one day. Task F is the largest EF time and
connected to the critical path and would shorten the overall length of this project by one day.
This is
Not the
correct answer
because It is more ex
pensive than option B.
E). This would Work in shortening the task by one day. Task G is connected to the largest EF
time Task F and connected to the critical path and would shorten the overall length of this
project by one day. This is
Not the
correct
answer
because It is more expensive than option B.
6.
I. This is
False
because task B is the longest task in the project.
II. This is
True
. There is only one project worked on in the first day and that is task A.
III. This is
True
for days 14, 15, and 16, the life of task E, you will also be working on task F.
7.
Its B.
The last task completed on this project, task F, is completed on day 17.
