A(2) B(4) C(8) D(6) E(7) F(4) G(5) Assignment 3 6) The critical path constitutes the most important part of any project because if any one activity on the critical path is delayed, the whole project is delayed. Anything off the critical path will have some slack time so that if it is delayed, it will not delay the whole project. Also, when trying to crash a project, activities not on the critical path do not need to be taken into account unless they are put on to the critical path by crashing another activity. Therefore, the important activities will always be on the critical path. 5) a. ABCD = 24 weeks AEGCD = 26 weeks < critical path AEFD = 25 weeks b. 26 weeks c. Neither F nor D are on the critical path so shortening them would not affect the completion date 9) a. ABDFG = 23 weeks ABDEG = 21 weeks ACDFG = 25 weeks < critical path ACDEG = 23 weeks

The critical path would remain the same. I would then crash activity C costing an additional $1,200.00 and shortening the schedule by 1 week. The critical path would remain the same and all together, crashing the project would cost an additional $2,200.00 11) a. b. critical path c. 18 weeks: no crashing = $500 17 weeks: crash A = $570 16 weeks: crash A,B = $650 15 weeks: crash A,Bx2,D = $810 14 weeks: crash A,Bx2,D,G = $960 13 weeks: crash A,Bx2,D,E,F,G = $1190 d. 18 weeks = $900 17 weeks = $920 16 weeks = $950 15 weeks = $1060 14 weeks = $1060 13 weeks = $1340 The minimum total project cost duration is 18 weeks...
