5 Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall 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

12 Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall Resource Leveling (Smoothing) A multivariate, combinatorial problem Objectives 1. To determine the resource requirements so that they will be available at the right time 2. To allow each activity to be scheduled with the smoothest possible transition across resource usage levels

13 Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall Prioritization Rules for Leveling 1. Smallest amount of slack 2. Smallest duration 3. Lowest ID number (FCFS) 4. Greatest number of successor tasks 5. Requiring the most resources

14 Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall Resource leveling (method one) Develop resource leveling table Determine activity Late finish dates Identify resource Over-allocation Level the resource loading table using priority rules Requires more than one run-through due to ripple effects Examine conflicts (apply priority rules) Select activity to be reconfigured Start over, looking for more conflicts

31 Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall Key Parameters in Multi-Project Environments  Schedule slippage  Possible $ penalty  Resource utilization  More efficient is better  In-process inventory  Reduce back log

32 Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall Prioritizing Resource Allocations in Multi- Project Environments First come first served Greatest resource demand Greatest resource utilization Minimum late finish time Mathematical programming

33 Copyright © 2013 Pearson Education, Inc. Publishing as Prentice Hall Demand vs. Utilization Personnel resources 3 writers, 3 painters and 3 sculptors Project A requires 3 painters for 2 weeks, 3 sculptors for 1 weeks and one writer for 1 weeks (10 artist/weeks) Greater Demand Project B requires 2 writers for 1week, 3 painters for 1 week and 3 sculpt0rs for 1 week (8 artist/weeks) Greater utilization 33
