STATISTICAL BULLETIN - VARIATION RESEARCH
Practical Approaches For Solving Reliability and Variation Research Problems
Have you ever wondered why so much of what is written in a statistical vein just doesn't get its point across? The reasons are quite clear --- the style is too abstract, meanings are hidden within a labyrinth of confusing terminology and symbolism, and too much is taken for granted in regard to ease and comprehensions. To put it differently, the practical approach to statistical methods is not very often employed. If we were, more people who need statistical methods in their daily work would begin to appreciate the advantages afforded by these methods and would be enabled to cope more effectively with statistical decision situations by using such techniques.
At Detroit Research Institute we endeavor to educate industrial and business personnel in fundamental concepts by taking the practical approach and simply explaining the logic behind such things as statistical decisions and then showing them in a manner which easy to grasp and easy to remember. We at Detroit Research Institute always believe to uncover the subject as of to cover the subject. In this way the solving of everyday problems is greatly expedited. In the topics of Statistical Reliability it is true, as in so many of our educational experiences, that what is usually taught in colleges and universities is inadequate for the real lif situations we face when on the job. Therefore, it becomes necessary to be further educated in the harsh realities of life in order to cope. In life testing, for example, college courses in statistics usually confine probability theory to the classical Binomial or Multinomial theories, which prove to be ridiculously unrealistic in practice. For this reason and others, such as the ignoring of Entropy and Bayesian Weibull procedures, we are presenting in the Bulletin on the latest innovations which make developmental and testing programs in product reliability truly manageable by giving sensible sample sizes and clear direction-cut directions in decision making in product reliability and confidence.
No reliability effort is really effective as long as its managers and engineers are uninitiated in statistical methods. The very purpose of the Statistical Bulletin is to present the reliability statistics and variation research in a practical fashion so as to enable practitioners to obtain answers so badly needed in the field of reliability, decision making, and continuing quality improvements. This is truly a unique publication for no where else can there be found such down-to-earth discussions of statistical problems which plague engineering and management organizations.
The Bulletin was suspended in 1999 after twenty-eight years of publication. The Bulletin is such a great need in industry and business that we felt it necessary to publish the important topics of the Bulletin in our other website, http://www.dri-weibull.com in order that interested people would have it available as a reference.
