Förbättring av internlogistik: En fallstudie vid SSAB Finspång : En studie om hur processkartläggning kan användas för att effektivisera interna logistiksflöden i tillverkningsindustrin

Sammanfattning

This study investigates the internal logistics flow within a manufacturing facility, with a specific focus on the interactions between planning, logistics, and production. The aim is to identify bottlenecks, inefficiencies, and improvement opportunities using process mapping tools grounded in Lean and Total Quality Management (TQM). The research combines empirical data from interviews, observations, and a survey, and is guided by a systems-thinking perspective.Value Stream Mapping (VSM) and process analysis reveal that internal handovers, redundant transports, and inconsistent communication are key obstacles to efficiency. These findings align with Lean theory, which emphasizes the elimination of non-value-adding activities such as waiting, transport, and excess inventory. The analysis also highlights a lack of standardized procedures and digital support, which contributes to delays and person-dependent coordination.The proposed improvements such as pull-based scheduling, real-time data integration, and layout optimization are expected to reduce lead times, increase resource efficiency, and improve working conditions. The results show that mapping current processes not only uncovers structural weaknesses but also creates a foundation for strategic improvements. The study concludes that enhanced synchronization between core functions is essential for achieving a stable and resilient internal logistics flow.
