Noise Factors, Dispersion Effects and Robust Design
There has been great interest recently in the use of designed experiments to improve quality by reducing the variation of industrial products. A major stimulus has been Taguchi's robust design schema in which experiments ...
Compensation and Employment Security
Research by economists supports a couple of Japanese management practices that seem to have been underemphasized in many Total Quality implementation efforts in the US - lifetime employment and linking pay to the accomplishments ...
Bringing Total Quality Improvement into the College Classroom
This paper describes a recent effort to infuse the Total Quality Improvement (TQI) approach, popularized by Deming and others, into an upper-division, junior-senior economics course at the University of Wisconsin-Madison. ...
An Application of Taguchi's Methods Reconsidered
Two aspects of Taguchi's methods for analyzing parameter design experiments that can be improved upon are considered. It is shown how using interaction graphs instead of marginal graphs, and how using the sample variance ...
The Role of Scientific Problem Solving and Statistics in Quality Improvement: Some Perspectives
Scientific method of observation and experimentation play a key role in quality improvement. In this article, I provide numerous examples of the use of scientific method and argue that this a vital catalyst for Total ...
Robust Product Designs, Part II: Second-Order Models
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 ...
Discriminant Upset Analysis
This report presents an application of discriminant analysis in setting rules for early warning indicators of process upsets in wastewater treatment plant operation.
An Investigation of the Method of Accumulation Analysis
A discussion of Taguchi's method for analyzing ordered categorical data.
Charts for Optimal Feedback Control with Recursive Sampling and Adjustment
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 ...
