\\'V lLlllll JU WISE\" L 20. Norton Industries is installing a new computer system. The activities, the activity times, and the project network are as follows: Activity Time Activity Time A 3 E 4 B 6 F 3 C 2 G 9 D s H 3 The critical path calculation shows B-DEFH 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 information is relevant: Time (weeks) Cost (3%) Activity Normal Crash Normal Crash A 3 1 900 1700 B 6 3 2000 4000 C 2 1 500 1000 D S 3 1 800 2400 E 4 3 1500 1850 F 3 1 3000 3900 G 9 4 8000 9800 H 3 2 1000 2000 a. Formulate a linear programming model that can be used to make the crashing decisions for this project. b. Solve the linear programming model and make the minimum cost crashing decisions. What is the added cost of meeting the 16-week completion time? c. Develop a complete activity schedule based on the crashed activity times
