Project Management Scheduling

Existing project management systems include functionality to produce schedules (called ‘leveling’ or ‘scheduling’).  OTS has devloped algorithms that use ‘squeaky wheel’ optimization to outperform this existing functionality.  The following table shows typical results obtained by comparing OTS algorrithms with the Primavera leveler for actual projects from the construction industry.

*the initial schedule had no overload

The following snapshot shows schedule optimization in PSOP for an aircraft assembly problem. The Primavera-leveled schedule is on top and the PSOP schedule on the bottom. Overload is shown in red. The PSOP schedule eliminates all (100%) of the overload and is approximately 30% shorter as well.
