1. DOUBLE-SAMPLING CONTROL CHARTS FOR ATTRIBUTES / GRÁFICOS DE CONTROLE POR ATRIBUTOS COM AMOSTRAGEM DUPLA
In this thesis, it is proposed the incorporation of the double-sampling strategy, used in lot inspection, to the np control chart (control chart for the number nonconforming), with the purpose of improving its efficiency, that is, reducing the out-of-control average run length (ARL1), without increasing the average sample size (ASS) or the in-control average

3. GRÁFICOS ADAPTATIVOS DE CONTROL DE PROCESO POR ATRIBUTOS / GRÁFICOS ADAPTATIVOS DE CONTROLE DE PROCESSO POR ATRIBUTOS / ADAPTIVE CONTROL CHARTS FOR ATTRIBUTES
It is important to investigate ways to improve the efficiency of the statistical control charts for attributes, because the controls for attributes typically require very large sample sizes for quick detection of changes in the process, and these sample sizes can be extremely undesirable or eventually unfeasible in many practical situations. The adaptive sch
