Week 2 CH3, Pg 85, Q13 For the network shown: A. Determine the critical path and the early completion in weeks for the project. Path Path Duration A + B + D + G = 5 + 10 + 6 + 4 = 25wks ( Critical Path ) A + C + E + G = 5 + 8 + 7 + 4 = 24wks A + C + F + G = 5 + 8 + 4 + 4 = 21wks ( Early completion ) Note: A project cannot finish in less time than its longest path. B. For the data shown, reduce the project completion time by three weeks. Assume a linear cost per week shortened, and show, step by step, how you arrived at your schedule. Activity Normal Time Normal Cost Crash Time Crash Cost A 5 \$07,000 3 \$13,000 B 10 \$12,000 7 \$18,000 C 8 \$05,000 7 \$07,000 D 6 \$04,000 5 \$05,000 E 7
