Resumen

This research focused on a Peruvian industrial distribution SME experiencing low inventory turnover, a typical problem of contexts with high demand change and limited inventory control. While prior works have explored Lean Warehousing and inventory policies individually, integrated efforts are scarce. This research aimed to improve inventory turnover through a data-driven model combining 5S, cycle counting, and a Min–Max inventory policy under continuous review. Following an applied case study methodology, we validated the results of the model through a hybrid strategy that involved a pilot implementation and simulation with the software Arena. A reduced logistics cost of 82%, a decrease in immobilized inventory by 76%, an increase in inventory record accuracy from 86% to 95%, and a reduction of not located products from 45% to 0.4% confirm that the integration of Lean practices with structured inventory policies boosts operational performance of SMEs. Future research may develop more sophisticated forecasting methods and explore the implications of the digital integration of inventory management on more value-added decision-making.
