This thesis explores the study and optimization of material supply flows to production lines and the improvement of warehouse logistics through a detailed analysis and redesign of the layout, aiming for a more efficient organization and storage of goods. The primary objective is to enhance logistics efficiency through the implementation of an inter-company milk-run system, aimed at reducing operational costs by addressing key factors such as labor requirements, transportation distances and times, flow frequencies, and the types and number of handling and transportation equipment utilized. This initiative, referred to as the “Runner Project,” is examined through a case study conducted at the Chivasso facility of the Tenneco Group, a key supplier in the automotive OEM and aftermarket industries.
