3. Recently, you were assigned to manage a project for your company. You have constructed a
network diagram depicting various activities in the project. In addition, you asked various
managers and subordinates to estimate the amount of time they would expect each activity to
take. Their responses (in days) were as follows:
Activity
A
11
C
D
E
Optimistic
(a)
4
8
3
2
7
Duration (days)
Most likely
(m)
7
10
6
4
8
Pessimistic
(b)
10
14
7
6
9
a) Calculate the expected mean time, standard deviation and variance of each activity?
b) Determine the critical path and the expected project duration?
c) Assume that the time required to complete a path is normally distributed. What is the
probability of completing the critical path in less than 17 days?
