In UPS Feeder Operations
Feeder Scheduling and Optimization System (FSOS) is an optimization system used by UPS’ local feeder operations to generate feasible, efficient feeder driver schedules which meet all UPS and labor work rules, including minimum and maximum driver hours and driver domicile restrictions. FSOS starts by evaluating all individual feeder movements, and then determines alternative ways for combining these movements into individual driver schedules. FSOS repeatedly improves the solution until improvement stops. FSOS is typically run quarterly in each of our operating districts.
In addition to the brown feeder fleet, UPS needs to hire third-party drivers and driver teams (called Expediters in UPS lingo) to help move the additional package volume the company handles during the busy peak time-frame leading up to the holiday season. The planners use the Expedited Feeder Scheduling (EFS) system to develop the routes these drivers run. UPS planners develop a list of the loads that will need to be moved by these third-party carriers, and EFS strings these loads together into a system of round-trip routes that moves all the loads within their specified time window at minimal cost. The planners have estimated that it would take about 20-plus people three to four months to develop a similar set of routes using traditional manual processes.
