Abstract. This study aims to determine the sigma level of the production process of a thermoplastics industry with the implementation of DMAIC approach. To achieve this purpose it was conducted interviews to know the production system, analysing the non-conformities in the produced forks. It was found that the industry has a sigma level that is the reality of industries in general, however, this level still does not equal to what is presented by large industries. The paper contributed to the improvement of industrial quality control, and the proposed method it is being evaluated so that other improvements can be implemented.
Resumo: O desempenho humano tem sido estudado em face às limitações impostas ao ambiente e que refletem no desempenho do colaborador. Para que os erros humanos sejam minimizados é necessário que sejam analisados e propostas medidas mitigatórias. O objetivo do estudo é adicionar o tipo de erro "lapso" a estrutura proposta por Vilela (2013). Posteriormente, é realizada uma análise de agrupamentos para observar quais modos de falha, comportamento elementar e processo de Berliner que causaram mais interrupções de energia elétrica entre os anos de 1998 e 2009. Para tanto, a metodologia foi baseada em uma análise de agrupamentos a qual auxiliou na divisão dos erros humanos por grupos de características semelhantes, fornecendo assim uma identificação mais realística do comportamento humano que ocasionou o erro. Por conseguinte, essa pesquisa fornece suporte para uma proposição de soluções que possam contribuir para a redução dos erros humanos. O resultado da análise de agrupamento identificou os grupos 3 e 4 como os maiores ocasionadores de interrupções de energia elétrica. Também foi realizada a mensuração dos custos envolvidos na interrupção de energia elétrica, evidenciado o alto valor do faturamento perdido pela empresa no período estudado. Abstract: Human performance has been studied in face of limitations imposed on the environment which reflect the performance of the employee. So that human errors are minimized it is necessary to analyze them, proposing mitigation actions. The aim of this research is adding error type "lapse" to the structure proposed by Vilela (2013). Subsequently it is carried out an analysis of groupings to observe which failure modes, basic behavior and Berliner process caused more electricity disruption between 1998 and 2009. To this end, the methodology was based on a cluster analysis which assisted in the division of human errors by groups of similar characteristics, thus providing a more realistic identification of human behavior which caused the error. Therefore this research provides support for a proposition of solutions that may contribute to the reduction of human errors. The result of cluster analysis identified the groups 3 and 4 as major sources of electric power outages. The measurement of costs involved in electric power interruption was also performed, which evidences the high loss of company's revenue in the studied period. Palavras
The growing concern for the welfare of workers in the work environment, the importance of widespread use of ergonomics in the different sectors of industry. Yet most corporate practices that work with rudimentary or great need for human handling of materials is not fully in line with the ergonomic aspects. Given this, this article aims to identify ergonomic hazards in mining to later propose improvements in the process. After a series conducted plant visits, found that workers are exposed to various ergonomic risks, which entails the need for new healthy practices in the workplace. Finally, a series of proposals are submitted in order to avoid possible occupational diseases.
