| Résumé | Dispatching large-scale fleets has been one of the fundamental aspects of managing heterogeneous truckload logistics. This operation involves optimization, visualization, and reporting of the resource plans meticulously crafted by expert planners and dispatchers on a daily basis. However, the limitations of human dispatchers, including errors in communication, routing, compliance, load planning, maintenance oversight, and neglect of driver preferences, can lead to lower customer satisfaction. We present FleetWiz, a Large Language Model-based (LLM) platform that enables logistics industry dispatchers to receive optimal recommendations based on real-time spatial data. FleetWiz seamlessly connects dispatchers, drivers, and resources, centralizing information within a unified resource-request network. This leads to enhanced transit times, reduced delays, and adaptive responses to dynamic conditions. It can execute tasks in different domains including filtering, optimizing, and answering questions based on the network of resources and requests. Specifically, a local Llama3 model is equipped with access to a geo-database for filtering, five different optimization methods for generating plans, and knowledge about the entire network and operations inside the company. Lastly, the tool's reliability, a generic interface for applying LLM agents alongside spatio-temporal optimization models, is demonstrated. The optimization models handle complex dispatching tasks requiring sequential reasoning, allowing the LLM to provide well-informed feedback based on the results. |
