- Abstract: This study introduces the Territory Design for Dynamic Multi-Period Vehicle
Routing Problem with Time Windows (TD-DMPVRPTW), motivated by a real-world
application at a food company's distribution center. This problem deals with
the design of contiguous and compact territories for delivery of orders from a
depot to a set of customers, with time windows, over a multi-period planning
horizon. Customers and their demands vary dynamically over time. The problem is
modeled as a mixed-integer linear program (MILP) and solved by a proposed
heuristic. The heuristic solutions are compared with the proposed MILP
solutions on a set of small artificial instances and the food company's
solutions on a set of real-world instances. Computational results show that the
proposed algorithm can yield high-quality solutions within moderate running
times.

Vehicle Routing Problems (VRP) are an extension of the Traveling Salesperson Problem and are a fundamental NP-hard challenge in Evolutionary optimization.
We introduce a novel optimization framework that uses a reinforcement learning agent - trained on prior instances - to quickly generate initial solutions, which are then further optimized by genetic algorithms.
For example, EARLI handles vehicle routing with 500 locations within 1s, 10x faster than current solvers for the same solution quality, enabling applications like real-time and interactive routing.
