Final answer:
The question requires creating a compressed project schedule using the least-cost method until the crash point is reached, considering crash cost, critical path, and total direct cost.
Step-by-step explanation:
The question asks for assistance in project schedule compression using the least-cost method, specifically reducing the schedule until the crash point of the network is reached, while updating the total cost after each move. The student is provided with activity information, including crash cost (slope), maximum crash time, normal time, and normal cost for each activity.
To begin the process, one must identify the critical path and focus on activities that can be compressed. One should calculate the cost to crash each activity per unit time and proceed with the one that incurs the least cost. This method continues iteratively until you reach the crash point of the network. During each move, the total direct cost is adjusted to reflect the increased costs due to crashing. Each step involves calculations using the given figures for normal and crash times and costs.
Crash cost, critical path, and total direct cost are key parameters in determining how to optimally compress a project schedule within budget constraints.
