INTEGRATING TIMES AND METHODS WITH KANBAN - A CASE STUDY IN THE AUTOMOTIVE INDUSTRY

Abstract

The automotive industry is characterized by its high complexity and the need for highly efficient and flexible production processes. In this context, the integration of classic tools, such as time and method studies, with lean manufacturing practices, such as the Kanban system, constitutes a relevant strategy for identifying bottlenecks, reducing waste, and increasing competitiveness. This article aims to analyze the combined application of chronoanalysis and Kanban in an automotive wiring harness production cell, seeking to understand their impact on line balancing and improving production flow. Methodologically, this is an exploratory case study with a quantitative approach, developed through the collection of operating time data, mapping of supply routes, and the implementation of Kanban cards and boards. The results show that, prior to the intervention, production stations operated above takt time, compromising efficiency. With the introduction of the Kanban system, combined with the standardization achieved through chronoanalysis, there was a significant reduction in waste, elimination of inappropriate activities, and improvement in cell balancing, with all stations operating within takt time and fatigue limits. As a contribution, the study demonstrates the practical applicability of the integration between classical methods and Lean tools, reinforcing its relevance for continuous improvement. Furthermore, it highlights the need for future research on the digitalization of Kanban (e-Kanban) and its integration into smart production environments, aligned with the principles of Industry 4.0.
