11. Resource Leveling (Smoothing)
A multivariate, combinatorial problem
(hard to provide optimal solution)
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. Prioritization Rules for Leveling
Smallest amount of slack
Smallest duration
Lowest ID number (FCFS)
Greatest number of successor tasks
Requiring the most resources

13. Resource leveling (method one)
Develop resource leveling table
Determine activity Late finish dates
Identify resource Over allocation
Level the resource loading table
Requires more than one run-through due to ripple effects
Examine conflicts (apply rules)
Select activity to be reconfigured
Start over, looking for more conflicts

22. A much better Way Use MS Project Enter resources
Assign resources to tasks
Use Resource leveling tool
Sample resource leveling.mpp

23. Resource Loading charts Method two
Create a project activity network diagram
Develop resource loading table
Determine activity late finish dates
Identify resource over allocation
Resource level the loading table

24. Creating Resource Loading Charts
Display the amount of resources required as a function of time.
0 A 4 Res = 6
4 B 5 Res = 2
5 D 9 Res = 7
9 E 11 Res = 3
4 C 7 Res = 2
11 F 12 Res = 6
Start with a network diagram

25. Creating Resource Loading Charts
Activity
Resource
Duration ES
Slack LF A 6 4 B 2 1 5 C 3 11 D 7 9 E F 12
Produce a table that shows the duration, early start, late finish, slack, and resource(s) required for each activity.

26. Creating Resource Loading Charts
Draw an initial loading chart with each activity scheduled at its ES. A 2 4 6 8 12 10 14 C B D E F

27. Creating Resource Loading Charts
Rearrange activities within their slack to create a more level profile. Splitting C creates a more level project. A 2 4 6 8 12 10 14 C B D E F

28. efficiency

29. Key Parameters in Multi-Project Environments
Schedule slippage
Possible $ penalty
Resource utilization
More efficient is better
In-process inventory
Reduce back log

30. Prioritizing Resource Allocations in Multi-Project Environments
First come first served
Greatest resource demand
Greatest resource utilization
Minimum late finish time
Mathematical programming
