Integrated Logistics Management Model for Metalworking Companies: A Case Study of JIT, ROP, and 5S Implementation

Inventory logistics is crucial for maximizing a company's productivity. It has evolved over the years into a science aimed at optimizing warehouse logistics. The objective of this research was to propose a logistics management model inspired by Just in Time (JIT), Reorder Point (ROP), and 5S tools for companies in the metalworking sector. To this end, an experimental applied improvement design was used, employing engineering techniques through four methodological phases, from diagnosing and analyzing the problem to analyzing the results. The contribution of this research aligns with improving the level of logistical service through the management of inventories and warehouses, aiming to increase customer satisfaction and thus contribute to the development of more efficient logistics management models tailored to the needs of modern companies. The main improvements include a reduction of 6 days in delivery times, an 80% decrease in the percentage of service orders experiencing stockouts, and a 61% reduction in inventory inaccuracy rates.
