Feedforward as a Supplement to Feedback Adjustment in Allowing Feedstock Changes
(2002)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 ... -
Five Ways Statistical Tolerancing Can Fail and What to Do About Them
(1997-09)In this article we explore the general non-robustness of traditional root sum of squares statistical tolerancing and describe, in particular, how it can fail. These are [1] deficiencies in the functional model, [2] lower ... -
Further Details of an Analysis for Unreplicated Fractional Factorials
(1987-02)Some important implications and statistical details of Box and Meyer's formal approach to the analysis of unreplicated fractional factorial experiments. -
How to Reduce Costs Using a Tolerance Analysis Formula Tailored to Your Organization
(1997-04)In volume production, a few pennies per unit can add up quickly. In such cases, it may be worth considering whether cheaper components might be used without jeopardizing quality. One element in many tolerance analyses ... -
Human Factors E-Security Workgroup Report of Findings
(2003-04)One of the greatest barriers to effective e-security are the human and organizational factors that contribute to and cause the technical and social vulnerabilities of an organization's computer and information system. The ... -
Identification of Active Factors in Unreplicated Fractional Factorial Experiments
(1987-02)How to pinpoint the most likely explanation for the results of unreplicated fractional factorial experiments. -
Improving Team Effectiveness
(1997-04)Much has changed since teams became popular in the 1980's. Teams are now an established approach for getting work done, and organizations have learned important strategies for making teams effective. But barriers to team ... -
Influence of the Sampling Interval, Decision Limit and Autocorrelation on the Average Run Length in Cusum Charts
(1998-09)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 ... -
Integration of Techniques in Process Development
(1990)The reasons for the need of an iterative approach to experimentation are explained. The consequent implications in the use of screening designs (fractional factorials and other orthogonal arrays), response surface designs ... -
An Investigation of OA-based Methods for Parameter Design Optimization
(1990)There exists simpler alternatives for analyzing the results of a designed experiment than the orthogonal array methods proposed by Taguchi. -
An Investigation of the Method of Accumulation Analysis
(1986-12)A discussion of Taguchi's method for analyzing ordered categorical data. -
Joint X and R Charts with Variable Parameters
(1998-06)Consideration of some popular methods applied in the context of problem solving along with the supporting thought process commonly observed in practice. -
Joint X and R Charts with Variable Sample Sizes and Sampling Intervals
(1996)Recent studies have shown that the chart with variable sampling intervals (VSI) and/or with variable sample sizes(VSS) detects process shifts faster that the traditional chart. This article extends these studies for ... -
Managing Our Way to Economic Success: Two Untapped Resources
(1986)American organizations could compete much better at home and abroad if they would learn to tap the potential information inherent in all processes and the creativity inherent in all employees. -
Maximum Likelihood Regression on Censored, Experimental Data Using a Spreadsheet Program
(1997-12)This article describes how to analyze censored, experimental data using an optimizing function in a spreadsheet program (such as Solver in Microsoft Excel or Lotus 1-2-3). -
My First Trip to Japan
(1986-02)American visitors to Japan can learn much about what it takes to successfully implement quality improvement. -
Needed Skills for Human Resource Professionals: A Pilot Study
(1997-11)This pilot study identifies the skills needed by human resource/industrial relations (HR/IR) practitioners and contrasts them with the emphasis currently placed on developing these skills in a single master's degree ... -
Noise Factors, Dispersion Effects and Robust Design
(1993-07)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 ... -
Nonstatistical Skills That Can Help Statisticians Become More Effective
(1996-03)The new economic era we live in has resulted in a variety of new work situations for statisticians. Many are asked to be a member of a team that involves several different functions of the organization. Statisticians are ... -
Normalizing Transformations for Shewhart-Type Control Schemes
(1994-05)Traditional Shewhart-type process control schemes and process capability analyses assume that the process distribution (or distributions of statistics derived thereof) are approximately normally distributed. When this ...
