In the context of the Peruvian distribution sector, small and medium-sized enterprises (SMEs) face significant challenges in warehouse and inventory management, impacting their operational efficiency and customer satisfaction. This study addresses these issues by implementing a logistic model that integrates Economic Order Quantity (EOQ) and Systematic Layout Planning (SLP) to optimize operations in a Peruvian plastic distributor. The proposed model aims to enhance warehouse organization, streamline inventory management, and improve delivery performance.

The research contribution involves a detailed application of the SLP methodology, combined with ABC analysis for product categorization and matrix tables for layout optimization. Additionally, the study incorporates EOQ for optimal order quantity determination and demand forecasting techniques to reduce stockouts. Key results demonstrate substantial improvements in operational metrics. Notably, on-time delivery rates increased by 18%, from 76% to 90%. Inventory stockouts decreased dramatically by 85%, reducing from 14% to 2%. The overall cycle time for order processing was shortened by 50%, from 60 minutes to 30 minutes. Furthermore, the effort required for picking and packaging activities was reduced by 33%, from 20,620 kg-mt to 13,820 kg-mt. These results indicate that the integration of SLP and EOQ models significantly mitigates the inefficiencies in warehouse management and inventory control, leading to enhanced operational performance and customer satisfaction in the distribution sector.
