1 Resource Management Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall

2 Chapter 12 Learning Objectives After completing this chapter, students will be able to: Recognize the variety of constraints that can affect a project, making scheduling and planning difficult. Understand how to apply resource-loading techniques to project schedules to identify potential resource overallocation situations. Apply resource-leveling procedures to project activities over the baseline schedule using appropriate prioritization heuristics. Follow the steps necessary to effectively smooth resource requirements across the project life cycle. Apply resource management within a multiproject environment

Publishing as Prentice Hall 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 12-07

9 Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall 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. Level the resource loading table 12-9

10 Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall Creating Resource Loading Charts (1/4) 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 12-10
