ABSTRACT Defining delivery routes is an effective way to reduce transportation costs. In particular, a cross-dock distribution center in a retail network requires coordinated decisions on delivery routes and internal operations, leading to the cross-dock scheduling with routing decisions problem. To the best of our knowledge, no empirical study has shown the advantage of integrating these decisions. Previous works mainly focus on fresh food distribution centers with specific operational features. Based on a retail network, we address this problem by developing two mixed-integer models: one basic and another with additional routing variables that improve the problem representation. Furthermore, we assess the importance of integrating routing and cross-dock scheduling by comparing integrated and hierarchical strategies. Overall, our results indicate that integration can improve the distribution system’s scheduling efficiency under different demand patterns and dependency levels between customers and suppliers.
Cross-docks are transshipment facilities used in logistics to consolidate freight by destination. This research addresses the cross-dock scheduling problem for a multi-door facility where inbound trailer arrival times are variable, products are interchangeable, and the objective is to minimize the makespan and the tar...
As urban agriculture evolves into networks of farms and stores, production, inventory, and delivery must be coordinated at the network level. However, prior studies have mainly focused on individual facilities, with limited attention to integrated logistics and supply-demand balancing. This study develops a multi-perio...

This study sets out to build an intelligent agent that plans vehicle routes and handles three-dimensional cargo loading at the same time and suggests that tying routing and loading together in a closed-loop setup makes plans easier to carry out.

This study addresses a single-depot stochastic inventory-routing problem with static inventory control policies and vehicle routing decisions. The model integrates precomputed safety stock values into a mixed-integer linear programming formulation, accounting for customer-specific demand variability and service level r...
