37. Given the following network information: (15 points)

Activity Predecessors

A None

B None

C B

D A, C

E D

Activity Normal Time, Normal Cost, Crash Time, Crash $ total

(Days) ($ total) (Days)

A 5 300 4 500

B 3 250 2 325

C 7 400 4 550

D 5 150 1 500

E 3 100 1 200

1. Draw the network diagram. This will help to solve the remaining problem #37 subsections. (not graded)

2. What is the Critical Path? (State the path as X-Y-Z) (1 points)

3. Calculate the Critical Path duration in days (1 points)

4. What is the slack time for Activity A? (2 points)

5. If Activity C is reduced to 2 days what is/are the new critical path(s)? (State the path as path X-Y-Z). (3 points)

f. What is the new duration of the new critical path(s)? (2 points)

7. Using the original Critical Path of (b.) above, which activity(s) should be crashed to meet a project deadline of 13 days from the critical path duration of (c.) above? (3 points)

g. What is the new total project cost after crashing the project to 13 days? (3 points)
