| Summary: | Nowadays, in the present dynamic industrial scenario characterized by shorter product life-
cycles, customization, and uncertain demand, corporations should enhance their efficiency
by reducing waste to remain competitive. This research addresses machine micro down-times, which embrace a significant waste source that negatively affects Overall Equipment
Effectiveness (OEE). Although the literature presents some studies suggesting methods to
mitigate micro downtimes, contemporary approaches focus on isolated strategies, lacking an
integrated methodology. Accordingly, a research gap remains in developing a comprehensive
framework that holistically improves OEE and systematically decreases micro downtimes
within processes with bottlenecks. In this context, the objective of this study is twofold. First,
we aim to introduce a Lean-based framework to reduce micro downtimes in manufacturing
processes. Second, we present the results of applying this framework in a Brazilian tire company through a practical research approach. The results demonstrate a 1.6% reduction in
machine micro downtimes, amounting to potential savings of USD 750,000 annually. Additionally, the implementation led to the improvement project's completion three weeks ahead
of schedule, showcasing the framework's effectiveness. Although validated in tire manufacturing, the adaptable framework shows potential for broader use in other industries, offering a
flexible approach to enhancing efficiency and competitiveness. |
