Resumo: The presence of autocorrelation violates the hypothesis of data independence used in statistical control charts in the manufacturing environment. This article examines graphically, using the Mahalanobis distance, the effect of autocorrelation in two measurable quality characteristics of X and Y, whose correlation and autocorrelation structures are from a VAR model(1). With the graphical evaluation, it is possible to understand that the presence of autocorrelation cannot be neglected by the users who use as statistical tool the control charts to monitor processes.

Este artigo avalia graficamente, utilizando a distância de Mahalanobis, o efeito da autocorrelação em duas características de qualidade mensuráveis X e Y, cujas estruturas de correlação e autocorrelação são de um modelo VAR(1). Com a avaliação gráfica, é possível compreender que a presença da autocorrelação não pode ser negligenciada pelos usuários que utilizam como ferramenta os gráficos estatísticos de controle para monitorar processos. ABEC2017-09-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmltext/htmlapplication/pdfapplication/pdfhttps://www.revistasg.uff.br/sg/article/view/65910.20985/1980-5160.2017.v12n3.659Sistemas & Gestão; v. 12 n. 3 (2017): SETEMBRO/2017; 252-91980-516010.20985/1980-5160.2017.v12n3reponame:Sistemas & Gestãoinstname:Universidade Federal Fluminense (UFF)instacron:UFFporenghttps://www.revistasg.uff.br/sg/article/view/659/716https://www.revistasg.uff.br/sg/article/view/659/717https://www.revistasg.uff.br/sg/article/view/659/697https://www.revistasg.uff.br/sg/article/view/659/729Leoni, Roberto CamposCosta, Antônio Fernando BrancoMachado, Marcela Aparecida Guerreiroinfo:eu-repo/semantics/openAccess2020-05-29T17:29:04Zoai:ojs.www.revistasg.uff.br:article/659Revistahttps://www.revistasg.uff.br/sgPUBhttps://www.revistasg.uff.br/sg/oai||sg.revista@gmail.com|| periodicos@proppi.uff.br1980-51601980-5160opendoar:2020-05-29T17:29:04Sistemas & Gestão - Universidade Federal Fluminense (UFF)false
