Question

The project manager of a task force planning the construction of a domed stadium had hoped to be able to complete construction prior to the start of the next college football season. After reviewing construction time estimates, it now appears that a certain amount of crashing will be needed to ensure project completion before the season opener. Given the following time and cost estimates, determine a minimum-cost crashing schedule that will shave five weeks off the project length. Note: No activity can be crashed more than two weeks.

Answer 1

Answer:

Hello your question has some missing data attached below is the missing data table

answer :

week  1 : C should be crashed at $5000

week 2 : C should be crashed at $5000

week 3 : F should be crashed at $12000

week 4 : F should be crashed at $15000

week 5 : P and E crashes at $20000 + $16000

Explanation:

Normal completion time = 49 weeks

and the critical path : ( C-F-I-J-P )

Estimate the a minimum-cost crashing schedule

At week  1 : the crash ( C )activity  should be at $5000 and the completion time here will be 48 weeks

At week 2 : The crash (C ) activity should be made at $5000 hence the completion time here will be 47 weeks

At week 3 : The crash ( F ) activity should be made at $12000 and the completion time will be at 46 weeks

At week 4 : The crash ( F ) activity should be made at $15000 hence the completion time will be set at 45 weeks

At week 5 : The crash activity P will be at $20000 and crash activity E will be at $16000 hence the completion time will be 44 weeks

attached below is the pictorial view of the minimum-cost crashing schedule
