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 ... -
On Robust Design in the Conceptual Design Phase - A Qualitative Approach and A Semi-Analytic Approach to Robust Design in the Conceptual Design Phase
(1995-07)One of the most important contributions to quality engineering over the last decades is the concept of robust design and its accomplishment through the use of various experimental methods. However, the prerequisite parameter ... -
Orthogonal Design of Life Testing with Replacement: Exponential Parametric Regression Model
(1994-03)This paper describes how to plan an "optimal" life testing experiment when the lifetime is assumed to have an Exponential distribution. We further assume that the mean lifetime is equal to where the covariates xi form an ... -
Process Control From An Economic Point of View-Chapter 1: Industrial Process Control
(1990-02)Some of the issues mentioned in technical Report #41 concerning the proper uses of Statistical Process Control and Automatic Process Control are discussed in greater detail in this report. -
Process Control From An Economic Point of View-Chapter 2: Fixed Monitoring and Adjustment Costs
(1990-02)The problem of choosing a control scheme that minimizes the combined costs of monitoring, adjustment and being off-target is discussed. In addition to the various costs, the choice depends on the nature of the disturbance ... -
Process Control From An Economic Point of View-Chapter 3: Dynamic Adjustments and Quadratic Costs and Chapter 4: Summary and Future Research
(1990-02)When a process is such that there is appreciable delay in control action taking effect, minimal variance feedback control can require excessive adjustment. In this report it is supposed that the cost of making the adjustments ... -
A Process for Consulting for Improvement in Quality and Productivity
(1986-11)A process that consultants can use to improve their effectiveness. -
Process Optimization: Going Beyond Taguchi Methods
(1991-05)This paper summarizes a speech given at the May 25, 1990 National Thermal Spray Conference in Long Beach, California. It is an expository paper which motivates the use of RSM for Product and Process Improvement and the ... -
Process-oriented Tolerancing for Multi-station Assembly Systems
(2002-10)In multi-station manufacturing systems, the quality of final products is significantly affected by both product design as well as process variables. However, historically tolerance research primarily focused on allocating ... -
Product Design With Response Surface Methods
(1998)In this article, methods for demonstrating the iterative process of investigation are presented. As one example, it is shown how the sequential use of response surface techniques may be applied to devise an improved paper ... -
Projection in 12-run Plackett and Burman
(1993-06)In this article we prove the form of the projections in the 12-run Plackett and Burman design. We do this by exploiting the close relationship between Hadamard matrices, orthogonal two-level arrays and a special type of ... -
Projective Properties of Certain Orthogonal Arrays
(1996)The projective properties of two-level orthogonal array designs are important in factor screening. General results are given which, in particular, allow the designs derived by Plackett and Burman to be categorized in terms ...
