ANÁLISE DE PERDAS ATRAVÉS DO CONTROLE ESTATÍSTICO DE PROCESSO: ESTUDO DE CASO EM UMA INDÚSTRIA DE MÉDIO PORTE

Abstract

This research aims to analyze the losses occurring in the production process of a food industry, where statistical methods were used in the milk, peanut and marmalade production line. The case study was carried out at the Doçaria Dois Irmãos, located in Anápolis state of Goiás, where all the data were obtained for the study. The Toyota Production System was used with some quality management tools for the identification and treatment of losses. The data were processed according to the Statistical Process Control, where the stability tests were performed in the production process stages, and this was done through the control charts. After stabilizing the production process with the interventions made in the industry, it was also possible to perform the process capability test, where it was verified that some process steps do not have capacity. Through the results obtained, it was also possible to measure financially the losses that were occurring in the industry, the inherent gains of the investments in the improvement actions and the time of return on the investment made. Thus, it was understood that the time of return on investments justifies the interventions in the productive process of the company in question. It was concluded, therefore, that the losses in the productive process of the industry under study, not only left the processes unstable and incapable statistically, but also was generating unnecessary production costs. By applying improvement actions in the industry, it was possible to raise important information within the production process, as well as increase the profit in the production line of the selected sweets, due to the reduction of losses in the process.
