INFLUENCE OF RELIABILITY ON THE TRADITIONAL CONTROL CHARTS: A “RELIABLE SHEWHART CONTROL CHART”

By Stefano De Falco and Nello Polese

Abstract

Abstract − The traditional control charts are based on the assumption that the measurement data relating to the average of each subgroup of the parameters under observation of a specific quality characteristic of product, process, system or service, are reported regardless of time stability of its own parameters. This condition is generally not verified in real cases, where we should take into account the lifecycle of measuring. In the case of monitoring of quality characteristic of a product for example, a parameter that is not in fact enjoy the property of time stability is its reliability, which is time-variant and it’s decreasing over time in force of degradation to which the product is subject. The traditional approach involves the construction of control charts with stationary limits, ignoring the possibility of an "adjustment " of those limits. This conceptua
