Influence of the Application of Lean Logistics in SMEs (Pharmacies) to Reduce Logistics Costs

The objective was to analyze and propose improvements for the product storage area through the application of Lean Logistics principles. A general diagnosis of the inventory process was conducted, with a focus on the storage area (critical area). Problems and their evidence were analyzed, and short- and medium-term proposals were developed. Flow diagrams and Pareto charts were created to assess the impact of these problems on productivity using the JIT (Just-In-Time) and Heijunka systems. Quantitative methods were employed to present the results. By implementing the Heijunka methodology, waiting times for product delivery were reduced from 49% to 21%. Additionally, the application of the JIT methodology increased storage accuracy from 80% to 99%, and inventory turnover experienced a significant improvement.
