Purpose – The purpose of this paper is to show the implementation of a maintenance management model based on total productive maintenance (TPM) in a production line of a metallurgical company, with high-precision equipment requiring effective maintenance to maintain the quality of the production process. Design/methodology/approach – Has been proposed a model for conducting the activities, emphasizing the training activities of the teams involved in the implementation, collection and analysis of industrial performance indicators from a year before the implementation of TPM. The development followed the timetable of activities and the results of these performance indicators were collected again after the application of the model. Findings – It observed that after the implementation of TPM, and the results of these performance indicators were collected again after the application of the model. Thus, it is concluded that the TPM assists in improving industrial performance and competitiveness of the production line studied. Originality/value – The angle, from which the paper approaches the TPM problem, is original for the studied company and shows positives results. It allows the company to apply the model in their others production lines and factories to achieve an improvement in industrial performance and competitiveness.
RESUMOCom a crescente concorrência e a necessidade de maior competitividade, as empresas que adotam o sistema de produção enxuta levam vantagem sobre as demais, pois tratam melhor as informações aumentando a sua eficiência. O objetivo desta pesquisa foi diminuir o lead-time da organização estudada, através da aplicação prática do Just-in-time em busca de uma produção enxuta em uma empresa metal-mecânica, fabricante de implementos agrícolas. Para atender a este objetivo realizou-se um estudo de caso de natureza qualitativa e de ordem descritiva. Para a coleta de dados utilizou-se inicialmente a observação e a análise documental para entender o processo produtivo. Após trabalhou-se com levantamentos de dados através de entrevistas estruturadas para identificar as dificuldades enfrentadas pelos fornecedores na entrega dos insumos dentro das especificações acordadas. A empresa estudada apresentava alto índice de atraso na entrega de seus produtos, devido ao elevado lead-time. Através da elaboração do mapeamento de fluxo atual, identificou-se que a organização trabalhava com uma produção empurrada e que muito dos atrasos ocorriam por problemas no fornecimento de insumos. Buscou-se a eliminação de tarefas que não agregavam valor ao produto final, elaborou-se um fluxo de valor enxuto para o processo, identificaram-se os principais problemas que levavam os fornecedores a entregarem os insumos fora das especificações ou dos prazos e sugeriram-se ações que poderiam ser aplicadas para eliminação destes atrasos. Através destas ações observou-se a redução no lead-time, auxiliando no melhor atendimento dos prazos de entrega, no aumento da competitividade, fato relevante para manter-se no mercado atual de equipamentos agrícolas.Palavras-chave: Produção enxuta, lead-time, equipamentos agrícolas, melhoria de processos, competitividade. ABSTRACTWith increasing competition and the need for improved competitiveness, companies who adopt the lean production system have some advantages, because they deal better with the information, increasing their efficiency. The objective of this study was to decrease the lead-time required by the studied company, by practical application of just-in-time searching for lean production in a metalworking company, manufacturer of agricultural implements. To meet this purpose, a case study of qualitative and descriptive order was carried out. To collect data, observation and documental analysis were performed, in order to understand the production processes, then working with the collection of data, through structured interviews in order to identify the difficulties encountered by suppliers in providing the supplies within the agreed specifications. The company had high indexes of late delivery of their products because of the high lead-time. Through the development of the mapping of actual flow, it was found that the organization was working with a production pushed and much of the late occurred because of problems in the supply of inputs. By eliminating tasks that did not add value to the final product...
