The project has 4 activities (A, B, C, and D) which should be completed sequentially to complete project. Probability distribution for time required to complete each of activities is given below.
Activity Time
Activity (weeks) Probability
A 5 .25
6 .30
7 .30
8 .15
B 3 .20
5 .55
7 .25
C 10 .10
12 .25
14 .40
16 .20
18 .05
D 8 .60
10 .40
i) Use the random number procedure to simulate completion time for activity. Sum activity times to establish the completion time for complete project.
ii) Use simulation procedure developed in part i) to simulate 20 completions of project. Illustrate distribution of completion times and evaluate probability that project can be completed in 35 weeks or less.
