Master’s Thesis: Defining the Boundary for Technical Cleanliness in the Supply ChainBackground Introduction Thesis work is an excellent way to get closer to Scania and build relationships for the future. Many of today's employees began their Scania career with their degree project. Background Technical cleanliness can affect component quality and the reliability and safety of battery production. Maintaining cleanliness throughout the supply chain — from component manufacturing and packaging through transport, goods receiving, storage, unpacking and final assembly — is therefore important for ensuring reliable and safe battery products. This thesis will investigate what measures are needed at different stages of the material flow to apply cleanliness requirements cost-effectively while safeguarding component quality. Possible measures may include supplier process controls, packaging and handling solutions, inspection and verification, and cleaning in production. The work will consider the complete material flow, including the technical, operational and cost implications of different approaches. The project aims to bring together R&D, Logistics and Production from a technical cleanliness perspective, focusing on material flow and cleanliness requirements throughout the value chain. Thesis objective Identify and evaluate cost-effective measures for applying cleanliness requirements across the supply chain and production flow, while safeguarding component quality and supporting reliable and safe battery production and products. The study should identify a cost-effective combination of measures that meets the cleanliness requirement, safeguards component quality and supports a robust production process. Scope and activities The students will: Map the end-to-end flow for selected components, from supplier processes to the point of use in production. Identify where contamination can be introduced, transferred or removed, including manufacturing, packaging, transport, goods receiving, storage, re-packing, unpacking and assembly. Review cleanliness requirements, current controls, inspection methods and cleaning processes. Assess how packaging, handling, storage conditions and process variation affect cleanliness over time. Compare supplier-side cleanliness control with cleaning in production, considering technical effectiveness, process robustness, feasibility, lead time, quality risk and cost. Identify the information and controls needed at each handover in the flow. Develop recommendations for where cleanliness should be established, verified and maintained, and where production cleaning is justified. Propose a decision framework that can be applied to other components or supply chains. The detailed component selection and access to supplier and production data will be agreed with the supervisors. Expected results The thesis is expected to deliver: An end-to-end flow and contamination risk overview for the selected case. A comparison of relevant supplie
