Document Summary
Steps in project crashing: compute the crash cost per ( crash cost - normal cost) crash cost per period =- ( normal time - crash time) time period. 2 . find the critical path / critical activities. 3 if there is only activity on this critical path , then select one critical path that : the can still be crashed nastnesmaneseoa. nu* per period. If there is more than one critical path , then select from each critical path such that : one activity. Each selected activity can still be crashed. " total crash cost of all selected activities is the smallest: update all activity times. " it desired due date has been reached , stop if not return to step 2. In cpm we assumed with no variability in times. Times a fixed time estimate for each activity times vary based on many factors in practice, activity. Pert uses a probability distribution for activity times to allow variability.
