Network analysis cost/time tradeoff
Crashing using incremental costs may, because of the difficulty of dealing with multiple critical paths, not lead us to a minimum cost solution for each possible project completion time. The package output giving the cost associated with crashing the project from its normal completion time of 24 weeks to 19 weeks (for example) is given below.

1. Compute the crash cost per week (or other time period) for each activity in the network. If crash costs are linear over time, the following formula Crash cost per period = (crash costnormal cost)/(normal timecrash time) 2. Using the current activity times, find the critical path(s) in the project network.
