A Charting Technique for Control of Low‐Defective Production

Goh, T.N. - In: International Journal of Quality & Reliability Management 4 (1987) 1, pp. 53-62

The technology of modern‐day production processes has improved to such an extent that situations could arise in which the proportion of defective items is so low that the conventional p chart is no longer appropriate for process control. An alternative charting technique, based on more exact...

Failure Models and Data Analysis Based on Ageing Properties

Newby, Martin - In: International Journal of Quality & Reliability Management 4 (1987) 3, pp. 36-46

Distributions are often characterised by their ageing properties, failure rates, residual life, etc. New failure distributions based on ageing properties are derived and some simple graphical techniques based on the ageing properties of distributions are demonstrated.
