    • Process Optimization: Going Beyond Taguchi Methods 

      Bisgaard, Soren (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 ...
    • Statistical Process Control and Automatic Process Control: A Discussion 

      Kramer, Tim; Box, George (1992)
      The roles of Statistical Process Control for process monitoring and of Automatic Process Control for process regulation are considered and common misunderstandings discussed. Simple examples are used to show how the ...
    • Charts for Optimal Feedback Control with Recursive Sampling and Adjustment 

      Luceno, Alberto; Box, George (1992-09)
      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 ...
    • The Design and Analysis of 2k-p x 2q-r Inner and Outer Array Experiments 

      Bisgaard, Soren (1992-09)
      Inner and outer array designs are useful for the development of robust products. In this article we will provide a discussion of their design and analysis from a classic factorial and fractional factorial design standpoint. ...
    • Bringing Total Quality Improvement into the College Classroom 

      Hansen, W. Lee (1993-03)
      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. ...
    • A Discussion of Scientific Methods for Setting Manufacturing Tolerances 

      Weiss, Paul R. (1993-04)
      Several traditional and newer techniques for setting manufacturing tolerances are discussed. The traditional methods include worst case, statistical case, and proportional and constant factor scaling. Newer methods, such ...
    • Compensation and Employment Security 

      Graves, Spencer (1993-06)
      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 ...
    • Role of Statistics in Quality Control 

      Box, George (1993-06)
      The role of Statistics in Quality Systems depends on certain philosophical issues which the author believes have been inadequately addressed. Three such issues are the role of statistics in the process of discovery, the ...
    • William G. Hunter: An Innovator and Catalyst for Quality Improvement 

      Box, George (1993-06)
      This is the text of a talk given at the Speakers' Dinner at the Sixth Annual William G. Hunter Conference on Quality in Madison, Wisconsin, on June 2, 1993. In it, George Box recalls Bill Hunter's pivotal role in the birth ...
    • Projection in 12-run Plackett and Burman 

      Tyssedal, John (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 ...
    • Noise Factors, Dispersion Effects and Robust Design 

      Burnsztyn, Dizza; Steinberg, David (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 ...
    • Total Life Models - An Important Tool in Design of Quality 

      Morup, Mikkel (1993-12)
      Product quality is far more than "fitness for use" and robustness in the manufacturing process. This paper discusses the phenomena of product quality in the entire product life. It presents a total life model which serves ...
    • Discrete Proportional-Integral Control with Constrained Adjustment 

      Luceno, Alberto; Box, George (1994-02)
      It is well known that discrete feedback control schemes chosen to produce minimum mean square error at the output can require excessive manipulation of the compensating variable. Also very large reductions in the manipulation ...
    • Orthogonal Design of Life Testing with Replacement: Exponential Parametric Regression Model 

      Gertsbakh, Ilya (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 ...
    • Normalizing Transformations for Shewhart-Type Control Schemes 

      Shor, Haim (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 ...
    • Tolerance Analysis Considering Manufacturing Variability and the Cost of Deviating from the Nominal 

      Graves, Spencer (1994-05)
      A number of different formulae for tolerance analysis and synthesis have appeared over the years. This article discusses the interrelationships between alternative formulae, showing how each is best for a specific set of ...
    • Assuring Product Success with ISO 9001? 

      Dalen, Gunhild (1994-07)
      Several research projects have been conducted, and several reports and books have been written with the hope of finding the factors important for successful new product development. This article compares the portions of ...
    • Redesigning the Introductory Statistics Course 

      Hoerl, Roger; Snee, Ronald D. (1995)
      There is general agreement that the traditional statistics course does not meet the needs of customer groups such as students and their future employers. While positive reform efforts are under way, many appear to be based ...
    • Total Quality: Its Origins and Its Future 

      Box, George (1995-01)
