Question
The following is a table of activities associated with a project at Bill Frigg Enterprises, their durations, what activities each must precede and the crash cost to reduce duration per week: Suppose that Bill Frigg Enterprises is only given 6 weeks (instead of 9) to complete the project. By how many weeks should each activity be crashed in order to meet the deadline? Assume that you can crash an activity down to 0 weeks duration. What is the total crashing cost? (Enter your response as a whole number.)Explanation / Answer
As per assumptions given, any activity can be crashed upto 0 days Activity Weeks Crash Cost/week A 2 $370 B 2 $110 C 4 $200 E 1 $140 F 3 $400 The current project duration is 9 weeks with critical path of A-C-F Another path is A-B-E-F with 8 weeks. Crashing should be done on activity with lowest crash cost/week on critical path Duration Path Initial Stage I Stage II A-C-F 9 8 6 A-B-E-F 8 8 6 Stage I Crash Activity C by 1 week (as it has lowest crash cost among A, C andF) Crash Cost = $200 Stage II Crash Activity C by 2 days and Activity B by 2 days so that duration of both paths remains same Crash Cost: C - $200 * 2 = $400 Crash Cost: B - $110 * 2 = $220 Total Crash Cost = $620 Activity Reduction A 0 B 2 C 3 E 0 F 0 Total Crash Cost = $200 + $620 = $820
