요약Logistics networks play a pivotal role in modern e-commerce by facilitating quick and efficient delivery services to customers. In practice, these networks are designed with a primary focus on cost-efficiency, typically relying on long-haul transportation for order deliveries. However, such long-haul trips often negatively impact delivery drivers' physical and mental well-being. In addition, such logistics networks are highly susceptible to a multitude of disruptions, ranging from low-impact events such as travel-time delays and facility power outages to major catastrophes like hurricanes and wildfires. Current literature has proposed methods to design logistics networks for long-haul transportation to sustain such disruptions, yet they often fall short in terms of practical scalability and providing sustainable working conditions for delivery drivers. Motivated by the new opportunities provided by the Physical Internet, this research aims to bridge this gap by designing large-scale resilient hyperconnected logistics hub networks to fulfill long-haul commodity demand through short-haul delivery trips using relay transportation. In particular, this research investigates the problem of relay logistics network design under different settings of partial information regarding commodity demand and potential disruption uncertainty.In Part 1 (Chapters 2-3), we study the problem of designing large-scale resilient hyperconnected networks under disruption risks, which aims to improve a network's efficiency and resilience through its topological configuration. We propose three modeling approaches based on mixed-integer programs that aim to open logistics hubs in order to connect each origin-destination pair using (i) multiple shortest paths, and (ii) multiple shortest edge-disjoint paths. We formulate these problems through pathbased and edge-based representations and leverage their structure to design scalable exact solution approaches based on tailored implementations of Benders decomposition and branch-and-price. We apply our methodology to design large-scale resilient relay networks for a China-based parcel delivery partner. Our computational experiments demonstrate that our developed approaches can obtain optimal solutions for practically relevant instances. The resulting logistics networks showcase a significant improvement in capabilities to sustain hub disruptions with marginal compromise on nominal efficiency, in comparison with relay networks designed to only optimize nominal efficiency. This work offers valuable managerial insights for logistics service providers aiming to design resilient relay networks with limited information regarding future demand and disruption risks. Our analysis provides decision-makers with recommendations on adjusting the topology of network designs to achieve a desired tradeoff between nominal efficiency and performance under disruptions.In Part 2 (Chapter 4), we study the problem of Capacitated Relay Network Design under Stochastic Demand and Consolidation-Based Routing, aimed at designing largescale relay logistics hub networks resilient to demand variability. We formulate the problem as a two-stage stochastic optimization model that integrates second-stage tactical consolidation decisions with first-stage strategic hub location and capacity planning. To solve this problem exactly, we develop a three-stage branch-and-cut algorithm with nested integer L-shaped cuts and Benders decomposition. Integer Lshaped cuts are generated by solving the consolidation subproblem for each stochastic demand scenario using a branch-and-Benders procedure. To accelerate convergence, we generate Benders optimality cuts by solving the dual of the continuously relaxed consolidation subproblem through nested Benders decomposition with shortest-path subroutines. Additionally, we derive valid inequalities and implement computational enhancements to further accelerate the algorithm. We validate our methodology by designing relay networks for finished vehicle deliveries in partnership with a U.S.- based car manufacturer.
