3. For the network shown: D(6) B(10) A(5) E(7) G(4) C(8) F(4) a. Determine the critical path and the early completion time in weeks for the project. b. 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. NORMAL NORMAL CRASH CRASH ACTIVITY TIME COST TIME COST $ 7.000 5 10 B D E F G Uouo 6 7 4 4 12,000 5,000 4.000 3,000 6.000 7.000 3 7 7 5 6 3 3 $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
