Abstract

This research was based on a specific case study at a lampshade manufacturing company. The problem was a lack of components in the finishing department, impacting deadlines. The objective of this research was to create an inventory control system in the finishing department to eliminate component shortages and improve service levels. The methodology used involved the construction of an inventory curve (ABC), value stream mapping (VSM), and the implementation of an inventory control system using the two-bin kanban system. The methodology included the study, analysis, and use of a production planning and control tool, relevant literature, and the company's service history. The results of the kanban implementation contributed to the elimination of stoppages in the finishing department due to a lack of components, which made it possible to eliminate stoppages in the production of lampshades due to a lack of rings and encouraged the teams involved to improve their understanding of the kanban's effectiveness. It can be concluded that this research is far from exhaustive, but it contributes to inventory control and customer service. For example, it avoided rush manufacturing and improved component flow, resulting in a perceived higher level of service for customers. Future work proposes extending the two-bin Kanban system to other departments within the company.
