Order picking and warehouse management is a key activity in any replenishment strategy. An inventory management model is proposed which can be managed through indicators such as order picking time and inventory turnover. For this purpose, a combination of different methods such as ARIMA forecasting, economic lot sizing (EOQ), 5S strategy and ABC technique were combined and taken to a simulation through ARENA software. Finally, the MAPE indicators were reduced from a range of 47.44% up to 79.39% to range of 5.93% up to 37.47%, which is the result of an initial situation versus a later improved one, as well as an increase in inventory turnover and a reduction in total order preparation time.
