A Lean Logistics Framework for Enhancing Inventory Management Efficiency: A Case Study in Peruvian Electrical Spare Parts SMEs

This research addressed the inventory management challenges faced by a Peruvian SME trading in electrical spare parts. Previous studies highlighted inefficiencies such as low turnover and stock discrepancies, yet failed to integrate comprehensive solutions. The study developed a Lean Logistics model incorporating 5S, Kanban, demand forecasting, and inventory control to optimize operations. Pilot implementation yielded measurable improvements: inventory turnover rose from 1.27 to 4.28, MAPE decreased by 68%, and record accuracy increased to 90%. These findings underline the model’s potential to enhance SME logistics efficiency and profitability. Further research could adapt this model for other industries or scales.
