System and method for incorporating origination and destination effects into a vehicle assignment process
First Claim
1. A system for determining the allocation of resources in a transportation industry comprising:
- a computer having access to a storage device, the storage device including a data base incorporating the identity, number and capacity of different vehicles available for transportation over a transportation industry'"'"'s service network including a plurality of predetermined routes;
the storage device further including instructions for allocating a vehicle to one or more predetermined routes based upon combined origination and destination and individual route effects of the vehicle assignment, the instruction using a series of linear approximations;
a computer output device communicably attached to said system; and
a computer input device communicably attached to said system.

Abstract
A comprehensive system and methodology for incorporating origination and destination network effects into a transportation industry'"'"'s vehicle assignment process. The invention utilizes a decomposition strategy to combine a simplified version of network segment-FAM with the network flow aspects of origination and destination yield management. The invention'"'"'s decomposition of the problem allows for the nonlinear aspects of the targeted origination and destination market effects to be isolated in origination and destination yield management, and subsequently incorporated in the vehicle assignment model using linear approximations to the total revenue function. The system operates either in "standalone" mode, or communicably attached to remote and local databases attendant to equipment and scheduling.

7. A method for vehicle assignment incorporating origination and destination effects comprising the steps, performed by a processor, of:
-
(1) initializing a fleet vehicle assignment model based upon assumed vehicle capacities; (2) generating fleet vehicle assignments and origination and destination fleet assignment model profit predictions from step 1; (3) generating origination and destination yield management network profit prediction and bid prices based upon fleet vehicle assignments; (4) comparing results of generated origination and destination fleet assignment model profit prediction to previously generated or produced origination and destination network profit prediction; and (5) generating a revenue approximation if previously generated or produced origination and destination fleet assignment model profit prediction and previously generated or produced origination and destination network profit prediction results are outside of a predetermined range. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
