In this paper we apply the strategy developed in Report 56 to a general second-order model. For this model we derive the robustness measure and give a series of tables of designs that are appropriate for the possible ...

This report presents an application of discriminant analysis in setting rules for early warning indicators of process upsets in wastewater treatment plant operation.

A discussion of Taguchi's method for analyzing ordered categorical data.

A cost model proposed by Box and Jenkins (1963) and later generalized by Box and Kramer (1992) for obtaining minimum cost for feedback control of processes is considered. Unfortunately, it is sometimes difficult to assign ...

This article discusses how an efficient organization is characterized by its knowledge and learning capability. It examines the learning ability of the human animal, the logic of continuous, never-ending improvement, the ...

Environmentally robust products and processes are designed to be insensitive to variation over the relevant ranges of the environmental conditions in which they need to operate. Split plots frequently provide efficient ...

This paper considers the complementary use of feedback and feedforward adjustments to compensate for anticipated step changes in the process mean as may be necessary in a manufacturing process each time a new batch of ...

This paper shows how the average run length (ARL) for a one-sided Cusum chart varies as a function of the length of the sampling interval between consecutive observations, the decision limit for the Cusum statistic, and ...

This article outlines some of the fundamental concepts of systems monitoring and general principles for the design of monitors to detect certain malfunctions in the powertrain system that may cause excessive emissions

The Six Sigma specification makes an allowance of 1.5 standard deviations for process drift. Simple ways in which a major part of such drift can be removed are given. These employ feedback adjustment methods specifically ...
