- The resource-constrained critical path is known as the critical chain
What is resource leveling?
- A resource optimization technique
- Start and finish dates are adjusted based on resource constraints with the goal of balancing demand for resources with the available supply
- Can be used when shared or critically required resources are only available at certain times, or in limited quantities, or over-allocated, or to keep resource usage at a constant level
- Can often cause the original critical path to change, usually to increase
What is resource smoothing?
- A resource optimization technique
- Adjusts the activities of a schedule model such that the requirements for resources on the project do not exceed certain predefined resource limits
- The project’s critical path is not changed
- Activities may only be delayed within their free and total float
- May not be able to optimize all resources
What is simulation?

- Works only for activities on the critical path where additional resources will shorten the activity’s duration
- Does not always produce a viable alternative
- May result in increased risk and/or cost
