Os benefícios e desafios na aplicação dos princípios do lean production em uma indústria de equipamentos hidráulicos: um estudo de caso

Abstract

Resumo: O objetivo desse artigo é mostrar os benefícios e desafios encontrados ao adotar o sistema Lean Production. A metodologia utilizada foi pesquisa bibliográfica seguida de um estudo de caso. A pesquisa de campo consistiu de um estudo de caso em uma indústria de equipamentos hidráulicos de capital americano situada na região de Campinas/SP. Nesse estudo foram registradas as mudanças efetivadas de acordo com os princípios do Lean Production, com os objetivos de aumento de produtividade, redução de defeitos e reestruturação de processos logísticos. Posteriormente, foi realizada a análise dos resultados obtidos por meio de gráficos comparativos mensais de volume de produção e controle de qualidade, que abrangeram desde a concepção do projeto até a sua conclusão. No geral, foi verificado um resultado positivo, que atendeu as expectativas previamente estabelecidas. Constatou-se um aumento significativo de 49,39% nos níveis de eficiência da linha de montagem objeto deste estudo, além de melhorias nos processos de áreas suporte, como qualidade e logística.Palavras-chave: Lean Production.

The methodology applied was literature review and field research The case study was done in the US firm producing hydraulic equipment, located in the region of Campinas/SP, where were registered effective changes according to Lean Production principles seeking productivity increase, defects reduction and restructuring of logistics processes. Subsequently were analyzed the results obtained by monthly quantitative charts of production volume and quality control covering from the conception to the conclusion of the project, getting a positive evaluation, meeting previous expectations after a significant increase in the efficiency level of the assembly line of this case study. In addition to the effective productivity increase of 49.39%, were developed improvements in processes of support areas, as quality and logistics.

“…The product and service chain has processes that may contain waste, so it is necessary to map their sources and eliminate them. This system was created by Toyota and is known as Lean production (Dante, Silva, & Piacente, 2019). According to Socconini and Martín (2019), in this system, there are ten significant sources of waste: overproduction, unnecessary processes, handling, transportation, waiting and searching time, over inventories, defects and rework, energy, talent, and contamination.…”

“…In the case tracked by Dante et al (2019), the achievement of improvements was possible through a PDCA cycle, where it was possible to plan, execute, do, monitor, and apply corrective actions to the processes. In addition, the company also adopted a layout change to reorganize and optimize the process, changed the process logistics, and started monitoring production indicators.…”
