Abstract
The research focused on solving the problems of high inspection and storage times in a spare parts warehouse serving as a distribution center for the dealers of an automotive retail company, identifying inefficient distribution and unnecessary transfers as the leading causes. A model based on Lean Warehousing and warehouse management with the lean tools, SLP and 7S, was implemented, which, after simulation in Arena software, resulted in an increase in productivity from 2.11 to 3.12 packages per man-hour and a 17% reduction in waiting times for spare parts packages. In addition, improved inspection and warehousing times were achieved, representing a significant reduction in associated costs, specifically in the reduction of expenses for using a support warehouse that amounted to $100,000 per year. This approach promises to be a model for improving warehouse management efficiency in the automotive retail sector.
