Statistical Properties and Sensitivity of a New Adaptive Sampling Method for Quality Control [PDF]
Revstat Statistical Journal, 2018 We present a new adaptive sampling method for statistical quality control. In this method, called LSI (Laplace sampling intervals), we use the probability distribution function of the Laplace standard distribution to obtain the sampling instants ...

Fitting X-bar Chart to the Traditional Transaction Surveys Analysis
Association of Marketing Theory and Practice Proceedings, 2010 Traditional transaction surveys such as service feedback cards (SFCs) are widely embraced by different service organizations to measure a service quality or to assess customer satisfaction with specific transactions. This paper pursues to apply the statistical quality control technique of -chart (X-bar) to analyze the scaled collected data of these ...

Design of X-bar control chart based on Inverse Rayleigh Distribution under repetitive group sampling
Ain Shams Engineering Journal, 2021 The X¯ control chart is usually used in statistical quality control (SQC) to observe the change in procedure mean. In this paper, X¯ control chart for Inverse Rayleigh Distribution (IRD) is designed under repetitive group sampling at lower record values.

Design of X-Bar Control Chart Using Multiple Dependent State Sampling Under Indeterminacy Environment [PDF]
IEEE Access, 2019 An X-bar control chart using the multiple dependent state (MDS) sampling under indeterminacy is presented in this paper. The MDS sampling utilizes the previous subgroup information if in-decision on the first sample. The use of MDS increases the power of

Bayesian Methods for Obtaining X-bar Chart: An Application on Food Quality Control
Journal of Institute of Science and Technology, 2015 This article is about the Bayesian methods of constructing control chart for process mean. The control chart for mean based on the use of normal prior distribution seems to be robust for normal observations. The concussion is derived from an experiment of a set of real dada of the weights of a food product filled in pouches.

A broader view of the economic design of the X-bar chart in the semiconductor industry [PDF]
International Journal of Production Research, 2009 This paper starts from a notice made in the semiconductor industry: a process control system and especially control charts provide information that can be exploited for correlation analyses during process investigations. In this industry, key and costly investigations are made for improving yield and reducing scrap. Daily, engineering teams are working

Exact run length distribution of the double sampling x-bar chart with estimated process parameters
South African Journal of Industrial Engineering, 2016 Since the run length distribution is generally highly skewed, a significant concern about focusing too much on the average run length (ARL) criterion is that we may miss some crucial information about a control chart’s performance.

DYNA, 2014 Recent advances in the design of control charts have focused on variable parameters charts (VP) in which parameters are modified according to the last sample value. These charts have proved more effective in detecting assignable causes but more complexes for implementation in organizations. Although, there is a lot literature regarding the economic and/
