Proposta e aplicação de um procedimento para análise da porosidade e de desperdícios em uma empresa de aeronaves

Resumo


Este estudo analisa o desempenho dos trabalhadores em uma empresa aeronáutica. Porosidade (ociosidade) foi definida como desperdícios referentes a comportamentos contraproducentes no trabalho, e a taxa de agregação de valor será analisada testando quatro hipóteses: diferenças entre técnicas de coleta de dados; diferenças entre os tipos de desperdícios medidos; variação da taxa de agregação de valor durante o dia de trabalho e relação entre ociosidade e informações sobre o perfil do operador. Os dados coletados do Sistema de Gestão Integrada (SGI) da empresa foram superiores aos observados, a ociosidade apresentou o maior valor dentre outros desperdícios, a parte da manhã teve maior valor agregado do que a parte da tarde (especialmente no final da manhã) e os trabalhadores que eram casados e tinham filhos apresentaram menor ociosidade. Este artigo mostra como a ociosidade é importante nas análises Lean no gerenciamento de operações e como o procedimento pode diminuir a ociosidade.


Palavras-chave
