The main goal of the thesis is to present the so-called Split Volume Cost Model (SVCM), engineered for logistics outsourcing purposes and fair for both the client and contractor. The first chapter is for context, so gives a broad presentation of logistics outsourcing: it describes the drivers that may convince a firm to pursue that direction but also the challenges and potential threats. It does it by breaking down and detailing the workflow that the companies involved go through, starting from the selection phase, up to full operations. The second chapter is the core of the thesis. The first two paragraphs are a long introduction that poses the foundation to understand the SVCM, explaining key concepts, dynamics and considerations.
