This study assesses the Value at Risk (VaR) and Expected Shortfall (ES) methods in gauging exchange rate risk in PT Telkom Indonesia Tbk, using historical Bank Indonesia closing rates USD/IDR and JPY/IDR from January 2022 - December 2022. Results demonstr... see more

La industria actual requiere  de sistemas de diagnóstico de fallos, que en su etapa de detección garanticen pocas falsas alarmas y logren detectar por demás, los fallos con la mayor rapidez posible independientemente de su naturaleza y magnitud. Sin ... see more

Selecting the correct control chart is essential to effectively monitoring process shifts. In particularly, a nonparametric control chart is recommended over a traditional control chart when the quality characteristics of a process are unknown. In this pa... see more

The exponentially weighted moving average (EWMA) feedback controller is a very popular run-to-run (RtR) process control scheme in the semiconductor industry. Traditionally, the manufacturing environment was simplified as a single ... see more

Intrusion detection is used to monitor and capture intrusions into computer and network systems which attempt to compromise their security. Many intrusions manifest in changes in the intensity of events occuring in computer networks. Because of the abilit... see more

En este artículo se presenta un caso de estudio, utilizando un monitoreo mediante la carta de control EWMA basada en varianza efectiva, para evidenciar como el aumento de la variabilidad de una de las características de calidad afecta en forma sensible lo... see more

The exponentially weighted moving average (EWMA) chart is very popular in statistical process control for detecting the small shifts in process mean and variance. This chart performs well under the assumption of normality but when data violate the assumpt... see more

In this paper, two new control charts have been proposed, one is shewhart-type and other one is EWMA-type control chart. The proposed control charts are based on the exponential type estimator for mean proposed by Noor-ul-Amin and Hanif (2012). We name th... see more
