| Abstract | The Location Routing Problem (LRP) is a pivotal component of logistics network optimization, integrating site selection and route planning to enhance the overall efficiency and performance of logistics systems. Emphasizing the integration of environmental, social, and economic factors, this dissertation applies sustainable development theory and focuses on an e-commerce logistics company in Nanning, China, to explore the application of LRP within this framework, aiming to optimize the logistics network for sustainable enterprise performance.Informed by sustainability perspectives, this dissertation employs mathematical modeling techniques from operations research to develop and analyze four distinct LRP models, each addressing the location-routing problem from different sustainability dimensions: economic, environmental, and social. The goal is to furnish enterprises with actionable logistics network designs and strategic insights. Each model's role is as follows:Model I focuses on economic sustainability, minimizing total costs while integrating time window constraints. This foundational model sets the stage for subsequent models, with an analysis revealing its cost-efficiency and strategic advantages over distance- minimization models.Model II enhances Model I by optimizing both economic and environmental impacts, particularly carbon emissions. Its solution, a Pareto frontier, allows for strategic selection based on corporate needs, revealing that cost and emission reductions are often conflicting objectives.Model III transitions from fuel to electric vehicles, emphasizing environmental sustainability and demonstrating that EVs can reduce costs and environmental impacts, supported by robust technology suitable for urban logistics.Model IV combines the three pillars of sustainability into a multi-objective LRP, showing inherent conflicts among objectives through a three-dimensional Pareto frontier. Sensitivity analyses on key parameters provide insights that guide future logistic strategies.This dissertation contributes significantly to the logistics field by showcasing how integrated logistics models can address complex sustainability challenges in urban settings, offering strategic insights for companies aiming to enhance their operational sustainability. |
