H_MDVRP

This repository provides three generated Multi-Depot Vehicle Routing Problem (MDVRP) instances, named H154, H264, and H365. The instances are built in the Cordeau format and include multiple depots. Each depot operates a heterogeneous fleet with its own vehicle-capacity and route-duration limits. The generated instances were checked for feasibility under the classical MDVRP constraints. These constraints require that each customer is served exactly once, while respecting vehicle-capacity limits, maximum route duration, and the available number of vehicles at each depot. The repository also includes several sub-instances derived from the original H154, H264, and H365 instances. These sub-instances are intended to support the study of customer exchange mechanisms in the Distributed Vehicle Routing Problem. Each sub-instance contains an initial assignment of customers to depots, where each depot represents a different company. This assignment corresponds to the pre-collaboration solution. The sub-instances were generated to evaluate the initial solution quality and compare it with the post-collaboration results.
