Método de estimativa dos limites da carta de controle não paramétrica que monitora simultaneamente a média e variância

Abstract: Resumo Os gráficos de controle clássicos para variáveis contínuas monitoram, separadamente, as medidas de posição central e de dispersão, conhecidas também como medidas de locação e escala. O monitoramento desses parâmetros tem como pressuposto que a distribuição de probabilidade dos dados seja conhecida e siga o padrão normal, o que, em situações práticas, nem sempre ocorre. Para isso foram desenvolvidos os chamados gráficos de controle não paramétricos. Este trabalho tem como objetivo desenvolver um método p… Show more

“…In [13], an NPCC based on Mann-Whitney statistics is compared to the classical Shewhart X-bar chart. Oprime [14] designed an NPCC with simultaneous monitoring of location and scale and compared it with classical Shewhart control charts. In [15], Shewhart S charts and NP-MAD charts are compared.…”

“…normal distribution, distributions with greater and lower kurtosis as compared to normal distribution, asymmetrical, two bimodal distributions and autocorrelated data were incorporated into these simulations. Other authors when simulating NPCC performance used fewer distributions, distributions with different parameters or quite different distributions, such as the β distribution [20]; normal and exponential distributions [14]; normal, Laplace and uniform distributions [12]; normal, Laplace and Gamma distributions [13]; normal, Student, Gamma, two symmetrical bimodal and one asymmetrical bimodal distributions [19]; and normal, uniform, Student, double exponential and Cauchy distributions [16].…”
