Gráfico de controle modificado para monitoramento de variância
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia de Produção - PPGEPCâmpus São Carlos, 2021-09-16)
Control charts are powerful tools used by many industries to monitor the quality of their processes and detect special causes of variation. They are often used to monitor the mean of some process quality characteristic ...
Double sampling (x)over-bar control chart for a first-order autoregressive moving average process model
(Springer London Ltd, 2008-11-01)
In this paper, we consider the double sampling (DS) (X) over bar control chart for monitoring processes in which the observations can be represented as a first-order autoregressive moving average (ARMA(1, 1)) model. The ...

Efeitos da estimação de parâmetros no desempenho do gráfico modificado considerando os índices de capacidade
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia de Produção - PPGEPCâmpus São Carlos, 2020-07-08)
The modified and the acceptance control charts are indicated for monitoring highly capable processes, whose natural dispersion is significantly lower than the specification limits. This affirmation is based on the fact ...

Monitoring and control of the multihead weighing process through a modified control chart1
(Universidad Nacional de Colombia (Sede Medellín), 2016-12-15)
Modified control charts are used to monitor and control manufacturing processes which are considered to be six-sigma processes. The use of these charts is based on the idea that the cost of identifying and correcting special ...
A modelagem de gráficos de controle de aceitação condicionados aos índices de capabilidade de processos : uma abordagem prática e econômica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia de Produção - PPGEPCâmpus São Carlos, 2017-07-07)
Modified and acceptance control charts allow a new approach to statistical process monitoring. This research topic is little explored in the academic world, thus, this thesis contributes to the advancement of statistical ...
Análise de desempenho do gráfico de Shewhart para o processo POMINAR(1)
(Universidade Federal do Rio Grande do NorteBrasilUFRNEstatística, 2017-12-08)
Since the industrial revolution to the present day it is in the industry's interest to monitor the quality of their products. That way, the techniques of statistical process control (SPC), especially control charts, are ...
