Method & Evidence

AimTo investigate the impact of lean manufacturing principles, specifically layout optimization, process flow reorganization, and batch size adjustment, on the Overall Equipment Effectiveness (OEE) of a sewing line.
MethodComparative analysis and simulation/modelling
ProcedureThe study involved analyzing the existing sewing line layout and process flow, identifying inefficiencies such as backflows and excessive transportation. A new layout and reorganized process flow were proposed to minimize these issues. The impact of varying batch sizes on waiting and transportation times was calculated, and an optimal batch size was determined by minimizing the sum of these times. The proposed changes were then implemented, and OEE was measured and compared to the baseline.
