Aplicação do sistema Kanban em propostas de melhorias no processo de abastecimento de peças de uma indústria automobilística para diminuir o tempo de entrega dos materiais

Abstract

The supply of parts is a crucial process to ensure that the factory produces its products with quality and within the defined timeframe. The central goal of the study is to propose improvements in the supply process between a distribution center and the internal warehouses of an automotive manufacturer using techniques from the Toyota Production System with a focus on the Kanban System to reduce or eliminate delays in deliveries, which result in drops in company production. To implement these proposals, a case study was conducted on the current supply process of the company and techniques were developed based on the Kanban System and the Toyota Production System focusing in Just in Time. Among the results obtained in the study it stands out an inventory with no excess or shortage of materials, the percentage of Kanbans delivered before the 24-hour mark increased from 60% to approximately 100% and a better control of Kanban cards' information through indicators that assist in the relationship with the parts supplier.
