Two-beam laser welding (TBLW) is an advanced process for precise, low distortion joining
of cylindrical miniature parts. The process is composed of a laser source, optics and various …

This paper presents an approximate average run length (ARL) of CUSUM chart for long-
memory process by using numerical integral equation (NIE) method based on Gauss …

EWMA) control chart is one of the control charts and can be used to quickly detect a small
shift. The performance of control charts can be evaluated with the average run length (ARL) …

Extended Exponentially Weighted Moving Average (Extended EWMA or EEWMA) control
chart is one of the control charts which can quickly detect a small shift. The average run …

From the principles of statistical process control, the observations are assumed to be
identically and independently normally distributed, although this assumption is frequently …

Abstract Statistical Process Control (SPC) can be defined as the use of statistical methods
and technicals to improve process productivity and product quality. One of efficient tools of …

The main purpose of this paper is to present the numerical integration of average run length
(ARL) for the Cumulative Sum (CUSUM) control chart. In addition, we compare the ARL …

In this paper we derive explicit formula for the average run length (ARL) of Cumulative Sum
(CUSUM) control chart of autoregressive integrated moving average ARIMA (p, d, q) process …

The Extended Exponentially Weighted Moving Average (Extended EWMA) control chart is
one of the control charts that can rapidly detect a minor shift. Using the average run length …

The efficiency of a process, especially a long memory seasonal autoregressive fractional
integral moving average (SARFIMA) process, has commonly been measured through the …
