The commercial sector currently has high demands for fast and accurate delivery of orders; however, there is a trend of increasing customer dissatisfaction that directly impacts product returns; this is mainly related to the logistics process of warehouse management.

The research shows the improvement of the On Time index to 80.73%, In Full to 86.46%, and OTIF to 69.80%. The proposed model was implemented through a pilot and simulated through Arena software. This research demonstrates that the application of the Lean methodology together with analysis tools is...
