The analysis of average run length of modified exponentially weighted moving average control chart using the Markov chain approach
Abstract:
This research presents a method for calculate and analysis the Average Run Length (ARL) of a Modified Exponentially Weighted Moving Average (MEWMA) control chart using the Markov Chain Approach (MCA). The MEWMA control chart was selected for this study because it is an enhancement of the Exponentially Weighted Moving Average (EWMA) control chart, which is known for its sensitivity in detecting small shifts in the process mean. The MEWMA chart inherits this strength and offers greater flexibility in parameter adjustment, making it suitable for various types of data. The MCA is a technique based on the principle of state transitions between the In-Control and Out-of-Control states. It is particularly suitable for ARL calculation, as it effectively models the behavior of control charts, which are used to detect shifts in process data over time. The results of this research demonstrate that the ARL calculated using the MCA method is both accurate and efficient compared to the ARL obtained via the Monte Carlo Simulation method, under the assumption that the process data are normally distributed and independent.
