Economic-statistical Design of NP Control Chart with Variable Sample Size and Sampling Interval
The control charts are graphical tools and proven techniques to improve the performance of a process. Usually, the processes are not naturally controlled, so the use of control charts will help to reduce the variability and increase the stability of the process. In the traditional approach, control charts with fix sample size and constant sampling intervals were used to identify the changes in ...
متن کاملan economic design of combined double sampling and variable sample size x ̅ control chart
abstract. in recent years several studies have shown that control charts with adaptive schemes or double sampling plans detect both small and moderate shifts in the process mean more quickly than the traditional shewhart chart. in the classical double sampling chart, the difference between two points were placed in the central region of first stage was not considered. in this study, a new co...
متن کاملEconomic Statistical Design of Multivariate T^2 Control Chart with Variable Sample Sizes
Today, quality improvement and cost reduction are key factors for achieving business success, growth and position. One of the primary tools for quality improvement and cost reduction in online activities of statistical process control is control charts. As the need for monitoring several correlated quality characteristics is extensively growing, the use of multivariate control charts become...
متن کاملEconomic Design of Variable Sampling Interval X-Bar Control Charts for Monitoring Correlated Non-Normal Samples
Recent studies have shown the X-bar control chart with variable sampling interval detects shifts in the process mean faster than the traditional X-bar chart. These studies are usually based on the assumption that the process data are independently and normally distributed. However, many situations in practice violate these assumptions. In this study, a methodology is developed to economically ...
متن کاملEconomic Design of T2 −V SSC Chart Using Genetic Algorithms
The principal function of a control chart is to help management distinguish different sources of variation in a process. Control charts are widely used as a graphical tool to monitor a process in order to improve the quality of the product. Chen and Hsieh (2007) have designed a T2 control chart using a Variable Sampling Size and Control limits (V SSC) scheme. They have shown that using the V SSC...
