**Mathematical analysis**

- Critical Path
- PERT
- GERT

__Critical Path __is where the path has the minimal float over the longest path

To calculate this, need duration of each task

Task Duration equals = Early Finish – Early Start or Late Finish – Early Finish

__PERT __estimating requires the following three things:

- TM = Time – most likely estimate to complete
- TO = Time – optimistic
- TP = Time – pessimistic

To calculate the expected activity time:

(TO + 4xTM + TP) / 6
