Cost Model: Crashing of Network

This process is repeated until the project crash point is reached. Procedure for crashing a project is explained hereunder: (i) The ratio of increase in cost to decrease in time for each activity that can be crashed on the critical path is calculated and compared. (ii) The activity having the lowest ratio is reduced to the next lower time value.
