Better Schedules
Consider the McDonnell Douglas Airplane Wing
example project that was shipped with PSOP. This project can be found in the wing.xer file in the example subdirectory of
your PSOP installation (by default this is C:\Program
Files\PSOP\Examples\wing.xer). The wing project is a real project
that McDonnell Douglas made publicly available for research purposes.
The goal is to build an airplane wing as quickly and with as
little overload as possible.
The Primavera leveler produces a 60 day schedule with 149 hours of
over-allocation on this project. It is possible to produce significantly
shorter schedules that contain no resource over-allocation.

| Project Duration |

148.95 hours |
0 hours |
Why did this happen?
The P3e leveler tries only one priority order when leveling. The order
it chooses may not be optimal. Indeed, for a moderately sized problem
there are more priority orders than there are atoms in the universe! It
is often unlikely that the one priority order used by the P3e
leveler will produce the optimal schedule. See the overview for more information on priority orders and how they affect leveling.
How can PSOP help?
PSOP uses On Time System's proprietary technology to intelligently try
many different priority orders. This results in shorter schedules with
less overload. For example, on the McDonnell Douglas Airplane Wing
project, PSOP produces a schedule that
completes 17 days earlier and removes all 149 hours of resource
over-allocation.
See the overview section for more information how how PSOP is able to reduce project durations and resource over-allocation.
