The study a new problem class, the Two-Echelon Multi-Trip Multi-Traffic Pickup and Delivery Problem with Time Windows and Synchronization. We consider the synchronization process of transshipment at satellites between vehicles with the temporary storage mechanism. As the proposed problem consists of two echelons with two separate fleets of vehicles, we thus propose the bottom-up approach to solve the problem. The experiment is to study the proposed model and analyze the satellite synchronization. |
