A new method for constructing confidence interval for Cpm based on fuzzy data
A measurement control system ensures that measuring equipment and measurement processes are fit for their intended use and its importance in achieving product quality objectives. In most real life applications, the ...
Confidence Interval for Cpm Based on Dp,q Distance
Problem statement: A measurement control system ensures that measuring equipment and
measurement processes are fit for their intended use and its importance in achieving product quality
objectives. Approach: ...
Hypothesis testing for the lifetime performance index based on ranked set sampling
Unreasonable decisions for the lifetime performance index could have serious cost for business. It is important to use an efficient sampling scheme in order to achieve better statistical inference. Ranked set sampling (RSS) ...
Assessing manufacturing process capability with imprecise data based on fuzzy Cpi
In the present study, we develop a realistic approach that allows the consideration of
imprecise output data resulting from the measurements of the products quality. A general method
combining the vector of ...
Baysian Estimation of Lifetime Performance Index Based on RSS Sample on RSS Sample
Lifetime performance index (CL) is a flexible and effective tool for evaluating product quality and conforming rate. Ranked set sampling (RSS) scheme is applied for Baysian estimator of CL based on square error loss. We ...
Assessing the Lifetime Performance Index based on Ranked Set and Median Ranked Set Sampling
In this paper, critical values for statistical testing of the lifetime performance index (CL) are calculated
with using Ranked Set Sampling (RSS) and Median Ranked Set Sampling (MRSS). These critical values
are ...
Lifetime performance index based on ranked set sampling
In this article, we assume that the lifetimes of products follow a one parameter exponential distribution and use both conjugate and Jeffreys prior distributions for finding a Bayes estimator based on the RSS
scheme ...
Sign control chart based on ranked set sampling
In this paper, ranked set sampling is proposed for constructing a nonparametric quality control chart based on sign statistic for monitoring the process center when the units are difficult and costly to measure. The ...
