Análise do impacto do lean manufacturing na redução de desperdício na linha de produção

Abstract

Lean Manufacturing has established itself as one of the most productive methods in the manufacturing sector, thanks to its ability to optimize production processes and eliminate waste. Because there is no universal standard for its implementation, it creates specific challenges in different organizations. This research sought to delve deeper into how the application of Lean Manufacturing practices and tools impacts productivity, waste reduction, and continuous process improvement in companies of different sizes. The study's overall objective was to analyze the impacts of applying Lean Manufacturing on the productivity of companies of different sizes, identifying the benefits, challenges, and contributions of practices and tools for optimizing production processes. The methodology adopted was a literature review with a qualitative and exploratory approach, using the multiple case study method to investigate Lean Manufacturing practices and tools implemented in different contexts. To this end, core concepts and tools such as Kaizen, Kanban, Just-in-Time (JIT), and 5S were investigated. Direct observations of management practices and organizational culture were also conducted. The conclusion is that, although lean production is a complex and demanding process, it can provide significant benefits when implemented correctly, such as increased productivity, improved product quality, and reduced costs. To sustain these results, it is crucial that organizations maintain a continuous commitment to improvement and adaptation to change, ensuring that the principles are internalized at all levels of the company.
