- 요약Last-mile delivery stands as a vital cog in supply chain operations, tasked with efficiently transporting goods from distribution hubs to their final destinations. In many scenarios, optimizing last-mile delivery requires intricate multi-period planning. Customers often present diverse visiting schedule options, compelling distributors to design both optimal visiting schedules and cost-effective daily routes for their transportation fleets. Within this complex landscape, the vehicle routing problem (VRP), particularly its periodic vehicle routing subclass, serves as a potent tool for conducting distribution optimization. Despite extensive research efforts and the emergence of various modeling and solution techniques in the literature for this combinatorial problem, disparities between theoretical works and real-world applications persist.This thesis is dedicated to bridging the gap between practical challenges encountered in last-mile delivery and the existing methodologies within the PVRP domain. To this end, two central challenges are addressed: incorporating operational constraints and transitioning to multi-period operation. The first challenge involves accommodating operational constraints that affect last-mile delivery efficiency. We start by constructing a versatile branch-price-and-cut framework capable of tackling PVRPs and their classic variants. Subsequently, we delve into specific practical considerations within last-mile delivery, such as work duration regulations leading to long-haul trips and workload equity. Leveraging our solution framework, we extend the existing state-of-the-art branch-price-and-cut approach proposed in the literature to adeptly handle problems featuring these characteristics.The second challenge revolves around transitioning from single-period to multi-period last-mile delivery operations. To address this, we introduce a comprehensive decision support framework armed with a rolling horizon simulation engine. This engine harnesses historical data to rigorously quantify cost savings associated with the transition, providing valuable insights for decision-makers.
