Module 5

6.

Given the following network with activity times in months, determine the earliest and latest activity times and slack for each activity.Indicate the critical path and the project duration.

(see diagram in the attached file)

13. Consider the network in problem 6, but with the following new time estimates for each activity:

time estimates (mo)

Activity a m b
1 4 8 12
2 6 10 15
3 2 10 14
4 1 4 13
5 3 6 9
6 3 6 18
7 2 8 12
8 9 15 22
9 5 12 21
10 7 20 25
11 5 6 12
12 3 8 20

Determine the following:
a. Expected activity times
b. Earliest activity times
c. Latest activity times
d. Activity slack
e. Critical path
f. Expected project duration and variance

17. For the CPM/PERT network in Problem 13, determine the probability that the network duration will exceed 50 months.

4. Good project managers are highly sought in business and industry. Describe your experience, if you have worked as a project manager. Alternatively, you can interview someone who may have led a large project in the past.
