Discuss the below:
1. Draw the network and identify the critical path. Also calculate the earliest-latest stav¬ing and finishing times for each activity:
Activity Preceding Activity Time (Weeks)
A — 4
B — 6
C A. B 7
D B 8
E B 5
F C 5
G D 7
H D. E 8
I F. G. H 4
2. On May I. Arnie Watson sent a memo to his boss, the director of project management, stating that the MX project would require thirteen weeks for completion according to the fig¬ure shown below.
Arnie realized that the customer wanted the job completed in less time. After discussions with the functional managers. Arnie developed the table shown below:
Activity Normal Crash Additional (Crash) Cast/Week
Time Cast Time Cost
A 3 6,000 2 8,000 2,000
B 5 12.000 4 13,500 1,500
C 5 16.000 3 22,000 3,000
D 4 8.000 2 10,000 1,000
E 2 6.000 1 7.500 1,500
F 3 14,000 1 20,000 3,000
$62,000
a. According to the contract, there is a penalty payment of 55.000 per week for every week over six. What is the minimum amount of additional funding that Arnie should request?
b. Suppose your answer to part a gives you the same additional minimum cost for both an eight-week and a nine-week project. What factors would you consider before de¬ciding whether to do it in eight or nine weeks?
