Question: 3. For the network shown: A(5) (B(10) ACTIVITY C(8) NORMAL TIME ABCDEFG 5086744 D(6) b. a. Determine the critical path and the early completion time

3. For the network shown: A(5) (B(10) ACTIVITY C(8) NORMAL TIME ABCDEFG 5086744 D(6) b. a. Determine the critical path and the early completion time in weeks for the project. For the data shown, reduce the project completion time (crash) by three weeks. Assume a linear cost per week shortened, and show, step by step, how you arrived at your schedule. 10 E(7) F(4) NORMAL COST $ 7,000 12,000 5,000 4,000 3,000 6,000 7,000 CRASH TIME G(4) 3775633 CRASH COST $13,000 18,000 7,000 5,000 6,000 7,000 9.000 Hint: Create 2 columns: Time Available to Crash and Incremental Crash Cost. Use the formula NT-CT to determine "Time Available to Crash". To determine the Incremental Crash Cost, use the formula (CC -NC)/Time Available to Crash. This will tell you the cost/week to crash each activity.
