Homework Content

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$($ies$)$ was crashed and the adjusted total cost.

Note: The correct normal project duration, critical path, and total direct cost are provided.

Please Use the table below for reference:

Note: Slope is defined as the cost to crash an activity by $1$ day. The maximum crash time is not the same as Crash Duration.
