n( reducing project cost and duration )

Use the information contained below to compress one time unit per move using the least cost method. Reduce the schedule until you reach the crash point of the network. For each move identify what activity(s) was crashed, the adjusted total cost, and explain your choice if you have to choose between activities that cost the same. Assume the total indirect cost for the project is $120 and there is a saving of $10 per time unit reduced. What is the optimum cost-time schedule for the project?
