Question: The critical path calculation shows B - D - E - F - H is the critical path, and the expected project completion time is

The critical path calculation shows B-D-E-F-H is the critical path, and the expected project completion time is 21 weeks. After viewing this information, management requested overtime be used to complete the project in 16 weeks. Thus, crashing of the project is necessary. The following table provides information on activity crashing. Time (weeks) Activity A B C D E F G H Normal 3 6254393 Crash 1 3133142 Cost ($) Normal 900 2000500 18001500300080001000 Crash 1700 4000100024001850390098002000 a. Formulate a linear programming model that can be used to make the crashing deci-sions for this project. b. Solve the linear programming model and make the minimum cost crashing deci-sions. What is the added cost of meeting the 16-week completion time? c. Develop a complete activity schedule based on the crashed activity times.
