Crashing Worksheet 7 Complete ALL Question in your book. Question 1: The activities and completion times for a project are shown in the network diagram below. The completion time of some of the remaining activities in the project can be reduced at a cost. The following table shows the reduced times (least possible time to complete an activity after maximum reduction of time). The cost of this reduction, per hour, is also shown. Activity Usual completion Reduced time Cost of reduction time (hours) (hours) per hour ($) A 6 3 50 B 5 4 100 C 2 2 - E 4 2 20 F 6 4 50 G 2 2 - Determine the shortest completion time for the project, the critical path and any float times for activities. i. Find the activities that should be reduced in time to minimise the completion time for the project. ii. Find the maximum time in hours that can be saved by this reduction. iii. Find the minimum cost to achieve this time saving.
