A heterogeneous fleet vehicle routing problem with time windows is first formulated and solved using exact and metaheuristic approaches. Then, a Solana-based smart contract is developed to ensure secure, transparent, and decentralized task management. The solution enhances cost efficiency, traceability, and sustainability across the delivery chain.enLast-mile deliveryVehicle Routing ProblemSimulated Annealing MetaheuristicBlockchainSolanaSmart ContractsSustainabilityThesis
