Question

Given below is the crashing data for a project along with other data. The project completion time is 20 davs. Determine: (a) the crash slope (i.e crash cost/day) for all activities, (b) the normal total project cost, (c) prioritized the list of activities for crashing from best to worst, (d) the best activity to crash if the project has to be completed in 19 days and alternative critical paths, if any, (e) the earliest time the project can be completed, and (f) the least cost of early completion. Do not use anv software.
