Consider the project network below. Suppose the duration of both activities A and D can be reduced to 1 day, at a cost of $15 per day of reduction. Also, activities E, G, and H can be reduced in duration by 1 day at a cost of $25 per day of reduction. What is the least-cost approach to crash the project 2 days? What is the shortest “crashed” duration, the new critical path, and the cost of crashing?
