4. 12-4 Resource Leveling (Smoothing) A multivariate, combinatorial problem Objectives To determine the resource requirements so that they will be available at the right time To allow each activity to be scheduled with the smoothest possible transition across resource usage levels

5. 12-5 Prioritization Rules for Leveling  Smallest amount of slack  Smallest duration  Lowest ID number (FCFS)  Greatest number of successor tasks  Requiring the most resources

6. 12-6 General Procedure for Leveling 1.Create a project activity network diagram 2.Develop resource loading table 3.Determine activity late finish dates 4.Identify resource over allocation 5.Resource level the loading table

7. 12-7 Creating Resource Loading Charts Display the amount of resources required as a function of time. 0 A4 Res = 6 4 B5 Res = 2 5 D9 Res = 7 9 E11 Res = 3 4 C7 Res = 2 11 F12 Res = 6 1.Start with a network diagram
