You (the project manager) have determined that your project needs to be crashed. The project's important information can be found in the table below. Calculate the Direct, Indirect, and Total Costs for a Cost-Time Duration Curve and make one too. What is the optimum cost-time (crash time) schedule? If the customer offers you $10 dollars for every week you can shorten the project from its original network, should you take it? If so, for how many weeks? Please Note: You have the necessary Indirect Costs for the remainder of the project under crashing conditions. They are: $300 for 27 weeks $240 for 26 weeks $180 for 25 weeks $100 for 24 weeks $70 for 23 weeks $60 for 22 weeks. Crash Cost Maximum Crash Normal Normal Act. Predecessor (Slope $/wk) Time Cost 40 3 10 80 50 100 D, B, E 20 Possible Paths: Start-A-D-F-End = 27 weeks....... Critical Path (longest path) Start-B-F-End = 14 weeks Start-C-E-F-End = 26 weeks The critical path is Start-A-D-F-End with duration 27 weeks. Direct Cost (Normal Cost) = 40+10+80+50+100+20 = $300 Indirect Cost (27 weeks) = $300 Total Cost = Direct Cost + Indirect Cost = 300 + 300 = $600 Part a and b: Optimum Crashing Schedule with Direct, Indirect and Total Costs Critical activities with least crashing cost/week to be crashed until maximum crash time for that activity is achieved Crashed Activity F No. of days Crashed Crashing Cost 30 30 1 30 60 A-D-F 30 150 30 120 Total Crashing Cost Critical Path / 1 30 90 | A-D-F 24 300 A-D-F | A-D-F A-D-F 26 25 23 22 Direct Cost 300 300 300 300 Indirect Cost 240 180 100 60 570 Total Cost = Direct Cost + Indirect Cost + Crashing Cost 540 490 490 510 Cost Time Duration Curve: Total 031 - Optimum abon 20pt . 26 25 24 21 Time Duration i week) Optimum crash time is 23 weeks with a total cost of $490 Part : Incorporation of $10 for shortening the project per week from the customer Crashed Activity No. of days Crashed 1 1 30 30 Crashing Cost Total Crashing Cost 30 120 A-D-F Critical Path | 150 A-D-F 22 25 23 Direct Cost 300 30 30 60 90 A-D-F A-D-F 24 300 300 180 100 540 1-20 1-30 460 300 300 60 Indirect Cost 240 Total Cost = Direct Cost + Indirect Cost + Crashing Cost 570 490 490 510 Customer's add on offer -40 -50 Net Cost 560 520 450 460 $10/week from the customer should be taken as it reduces the total cost. This should be done till the 4th crashing is complete and the duration shortens to 23 weeks. The resulting total project cost would be $450
