Aplicação de técnicas tradicionais e de séries temporais no controle estatístico da qualidade

Maria Emilia Camargo, Helio Ricardo Friedrich


In this paper the Statistical Quality Control of the production line of three machines of MAXION company, from Canoas, RS, by the basic procedure of Shewhart, as well as the alternative techniques; technique of Cumulative Sum (CUSUM) and Model of Exponential Smoothing are presented. On synthesis, notice that the procedure of Shewhart can be used at the detection of great changes at the mean of process and the method of cumulative sum is more efficient to detect little changes at the mean of process.
