Resumo

O balanceamento de linha (LB) é uma ferramenta de manufatura enxuta que otimiza a alocação de tarefas, reduz o tempo de inatividade e aumenta a eficiência operacional. Este estudo foi conduzido em uma empresa de manufatura do setor industrial, avaliando quatro de suas 19 linhas de montagem (21%) que apresentam baixa produtividade, altos níveis de desperdício e atrasos nas entregas. Esta pesquisa demonstra o impacto do balanceamento de linha no desempenho do processo, bem como a economia associada à sua implementação. Dois objetivos também são abordados: primeiro, identificar fatores externos, como o absenteísmo de funcionários, que afetam negativamente a produção e quantificar seu efeito no desempenho operacional; segundo, explorar ferramentas de manufatura que ajudem a mitigar esses impactos, desenvolvendo estratégias de solução voltadas à melhoria contínua. O estudo utiliza uma abordagem quantitativa, analisando a relação entre o percentual de atividades que agregam valor e a produtividade (peças por homem-hora), demonstrando que a implementação adequada do LB melhora o desempenho do sistema de produção. Os resultados do estudo oferecem soluções práticas e sustentáveis para lidar com a variabilidade operacional e aumentar a eficiência da produção.
