Dengue is a severe mosquito-borne epidemic disease. There no effective vaccine for dengue, so real-time surveillance system becomes crucial to detect dengue outbreaks. Control charts have been widely used as efficient tools identify changes in health-related data. In Hong Kong, the environmental protection department uses area ovitrap index survey monthly number of mosquitoes different areas. S...

Control charts (CCs) are one of the main tools in Statistical Process that have been widely adopted manufacturing sectors as an effective strategy for malfunction detection throughout previous decades. Measurement errors (M.E’s) involved quality characteristic interest, which can effect CC’s performance. The authors explored impact a linear model with additive covariate M.E on multivariate cumu...

This paper develops a new multivariate control charting method for vector autocorrelated and serially correlated processes. The main idea is to propose a Bayesian multivariate local level model, which is a generalization of the Shewhart-Deming model for autocorrelated processes, in order to provide the predictive error distribution of the process and then to apply a univariate modified EWMA con...

abstract. in recent years several studies have shown that  control charts with adaptive schemes or double sampling plans detect both small and moderate shifts in the process mean more quickly than the traditional shewhart  chart. in the classical double sampling  chart, the difference between two points were placed in the central region of first stage was not considered. in this study, a new co...

Statistical technique used to analyze quality problems and improve process performance is Process Control (SPC). In this study, multivariate control chart the of graduates Statistics Study Program, FMIPA USK, namely using Multivariate Exponentially Weighted Moving Average (MEWMA) average, Variance (MEWMV) variability, analysis Capability assess entire process.
