Traditional attribute control charts are based on the monitoring of the number of nonconforming items in a sample of fixed size. In modern manufacturing processes, since items can be checked automatically, use of samples of a fixed subjective size with traditional charts is not suitable for...

Describes the process and outcomes of operationalizing the 14 dimensions underlying the SPC implementation/practice construct. Employs a standard procedure to create a measurement instrument comprising 14 measurement scales, with the number of constituent measurement items ranging from one to...

It is widely considered that the advanced statistical quality improvement techniques (ASQIT) such as design of experiments and Taguchi methods form an essential part of the search for effective quality control. These quality improvement techniques are well established methodologies in which...

This paper discusses the concepts of static and dynamic quality enunciated by Robert Pirsig in relation to concepts of variation and statistical control enunciated by W. Edwards Deming. The relationship between static and dynamic is seen to reflect a fundamental truth present in many systems,...

This paper proposes a simplified procedure to approximate optimal values for the sample size, control limits, and sampling interval of a control chart based quality control station. The procedure considers the specifications in evaluating the control limits, permits asymmetry in these limits and...

We present two contingency rules to control a production process subject to a single assignable cause, i.e. the process shifts from in‐control to out‐of‐control state when the single assignable cause occurs. In this paper, we assume a 100 per cent inspection policy as opposed to the...
