Properties of some minimum run resolution IV designs
The regular resolution TV fractional factorial designs described in the have many desirable properties; main effect estimates are uncorrelated and are unbiased by two-factor interactions, whilst estimates of the two-factor interaction effects are limited to the identification of a significant …

Statistical process control with special reference to multivariable processes and short runs
The quest for control and the subsequent pursuit of continuous quality improvement in the manufacturing sector, due to increasingly keen competition, has stimulated interest in statistical process control (SPC). Whilst traditional SPC techniques are well suited to the mass production industries, …

Precision of the path of steepest ascent in response surface methodology
This thesis provides some extensions to the existing method of determining the precision of the path of steepest ascent in response surface methodology to cover situations with correlated and heteroscedastic responses, including the important class of generalised linear models. It is shown how the …

Controlling processes with reference to costs, item price and process evolution
This thesis presents some recent work of the author in developing the analysis of a number of process control models that take into account statistical, economic and other practical issues. Special attention is paid to the problem of optimum selection the initial process mean setting, with …
