CrashCRASHING THE PROJECT

- Calculate the Normal duration & Crash duration of all the activities (use proper logic and physical constraints) - Calculate the Normal cost & Crash cost of all the activities - Calculate the Slope of all the activities (ie., C / D = cost per day) - Follow proper sequence & crashing rules and crash the project activities, plot the least cost curveExample :

NOTE:Back to AbstractC = Diff b/w crash cost (CC) and normal cost (NC)D= Diff b/w normal duration (ND) and crash duration (CD)D1= "Reduced by" duration of the concerned activityC1= "Increase in cost" of the concerned activity due to crashingDL= "Balance" duration available for an activity to crash
