Abstract

This thesis examines the operational processes of Third Party Logistics (3PL) companies, focusing on the optimization of warehouse and distribution flows through the use of modern information systems and performance measurement tools. The study is based on a case study of Sarmed S.A., one of the most structured and technologically advanced 3PL providers in Greece. Initially, the theoretical framework of 3PL services is presented, along with the core functions of a multi-client warehouse and the role of WMS, ERP, and TMS systems in supply chain management. The analysis then focuses on the end-to-end operational flow at Sarmed, covering inbound processes (receiving, quantitative and qualitative controls, put-away) and outbound activities (picking, packing, shipping, and carrier integration), with emphasis on standardized procedures (SOPs), full traceability, and compliance with different customer SLAs. Special emphasis is placed on data-driven management, enabled by WMS event tracking and the monitoring of key performance indicators (KPIs) such as cycle time, picking accuracy, productivity, and on-time delivery. Through the analysis of real operational data, the study demonstrates how dashboards and performance metrics support informed decision-making and continuous process improvement. Finally, the thesis presents conclusions and improvement proposals related to further automation, resource planning optimization, and enhanced operational transparency toward customers. The findings highlight that the success of a modern 3PL provider relies on the effective combination of technology, standardized processes, and measurable performance, supporting sustainable and scalable growth.
