Improving efficiency of material flows in an automotive assembly plant: A case study

This paper investigates the in-plant logistics processes in automotive manufacturing and specifically, the material flows between the storage facility, the production lines, and the internal returns area. The aim is to improve the efficiency of the plant by looking at the current material flows of the case study company. Qualitative and quantitative data was collected through interviews and personal observations and was analysed. Using discrete event-based simulation, the current material flows were investigated. Our analysis showed that in plant's internal returns area efficiency gains are possible by reducing traffic congestion. A solution with minor changes in the layout was proposed and tested which showed an increase in the capacity of the system and a reduction in delays. (C) 2021 CIRP.
