A control chart plots measured values along with upper and lower quality control limits. Values appearing outside these limits are unacceptable and could indicate a manufacturing problem. Although ...

Control charts have been widely used for monitoring production processes and identifying assignable causes of variability. Many papers investigate the application of control charts in different ...

Fuzzy control charts represent a significant evolution in Statistical Process Control (SPC) by addressing intrinsic uncertainties in measurement and human evaluation that classical approaches often ...

The choice of control chart parameters-sample size, sampling interval, and control limits-is considered from an economic point of view. A general process model is considered, and the hourly cost ...

The extent to which products meet specifications needs to be systematically monitored in a production process. Product quality will typically be defined by two quantities: deviations from stated ...

The use of multiple control limits and multiple corresponding levels of response for processes is an effective way for statistical process control when different assignable causes exist which lead to ...

An effective ASC infection control program must be robust. It should involve many individuals at the ASC, from staff members all the way up through leadership. It must also include many different ...
