Abstract

This study improves the internal supply of critical materials for pinch valve production in a Peruvian metalworking firm by applying Material Requirements Planning (MRP), ABC classification, and Systematic Layout Planning (SLP) to reduce lead times and enhance inventory flow. A representative sample from key warehouses was analyzed. AS-IS and TO-BE scenarios were simulated in Arena (62 replications) evaluating picking time, logistics lead time, and fulfillment rate. Results show a 10% drop in picking time and a more than 23% rise in fulfillment, confirming the combined tools’ effectiveness. The scalable methodology offers benefits for similar production lines.
