a). Show the network for the project.
b). Develop an activity schedule for the project using normal times.
c). What are the critical path activities and what is the expected project completion time?
d.) Use the Trial and Error Method to solve this problem. What is the Total Cost of Crashing including the Normal Cost?
Paths are:
A-B-C-F = 33 weeks
A-D-E-F = 31 weeks
So, critical path is A-B-C-F
Total added cost due to crashing = 1,52,500
