Dynamic vehicle routing in multi-stage distribution networks

A computer readable storage medium storing a program of instructions executable by a machine to perform a method of determining a routing of vehicles for pickup and delivery in a supply chain network, comprising:

• generating a plurality of candidate set of routes for vehicles for pickup and delivery to meet demand at multiple target locations;
• determining unsatisfied demand at said multiple target locations resulting from completing pickup and delivery according to said plurality of candidate set of routes;
• selecting a set of vehicles routes from said plurality of candidate set of routes that minimizes said unsatisfied demand across all said multiple target locations by applying an optimization function.

A system of determining a routing of vehicles for pickup and delivery in a supply chain network, comprising:

• a processor operable to generate a plurality of candidate set of routes for vehicles for pickup and delivery to meet demand at multiple target locations, the processor further operable to determine unsatisfied demand at said multiple target locations resulting from completing pickup and delivery according to said plurality of candidate set of routes, the processor further operable to select a set of vehicles routes from said plurality of candidate set of routes that minimizes said unsatisfied demand across all said multiple target locations by applying an optimization function.
