President's Message
Duane Cook

As I write this, I am preparing for our upcoming Board of Directors meeting, to be held 18 Jan during the RAM Symposium. I am certainly looking forward to getting together with as many members as possible, to make decisions for improving our Society. I have received a lot of the Ballots and Proxies, and hope to get the rest soon. Our Agenda for the meeting calls for a lot of discussion and action, as we work to take SRE into the next millennia.

Thinking about the upcoming RAM Symposium has brought back memories of the first Symposium I attended. It was January 1986, in Las Vegas. I remember entering one of the conference rooms, and seeing everyone looking stunned. Shortly thereafter, I too had a stunned look on my face, as I watched in horror the replay of the Challenger disaster that had just occurred. As a young RAM intern, I found that terrible incident brought home to me just how important our work in the Reliability field is. Lives can and do depend on our ability to ensure that our products work reliably and safely. Although 13 years have passed since that terrible incident, the critical role Reliability engineering plays has not diminished. In today's environment, it is ever more important to ensure that we can have confidence that our products work as specified for as long as specified. Events such as the Annual Reliability Symposium go a long way to helping us stay current in our field. I hope as many of you as possible will attend this year's Symposium, and our Board of Directors meeting as well.

In the next issue, I will be reporting on some of the major items discussed during the meeting. A complete set of minutes will also be sent to you chapters. Please feel free to contact me, or any of the other Executive officers, to keep us up to date on your chapter's activities, needs, and concerns. As I said in my last message, it is through continual communication and mutual effort that we will grow our Society.

Duane Cook



From The Editor
Richard Youngk

Here we go again. I'd like to repeat our goal for Lambda Notes.... to continue to develop communication among our chapters and to provide information for the RAMS symposium.

Again, we are featuring one SRE chapter with each issue, Buffalo Chapter with this issue. Feature articles will include chapter meeting descriptions, schedules, membership interests and contacts. A bit of SRE history .... Buffalo Chapter's Ed Banaszak originated this pamphlet format during his term as editor in 1994 .... thanks Ed!!!.

What's new in this issue of Lambda Notes (LN)? ... "Chapter News and Information". I have attempted to call each chapter contact and to compile a summary for all chapters in Lambda Notes. Those missed will be included next issue! Also new... the advertisement section. Thanks to Cambridge University Press for leading the way!

Next issue, we will feature Atlanta Chapter. Other chapters should begin to prepare for following issues by preparing chapter histories, list of upcoming events, current club member information and by maintaining club meeting summaries.

Oops! Thanks to our alert readers, there were several corrections identified on the July issue book review, "Reliability Engineering". The variables"n" and "v" were not capitalized in several places.

This position of LN Editor is an excellent position for learning about our organization. When calling the Chapter contacts I was humbled by the wealth of organizational and professional experiences of our SRE members. It is apparent to me that the strength of SRE is a result of the quality and dedication of our members. This experience is adding a great deal to my professional growth and I am sure will prove an invaluable experience for my career.

Until the next issue
Richard Youngk

Universal Standards for the Development and Enhancement of Customer Satisfaction
A Buffalo Chapter Presentation
by Thad Woronowicz, Senior Staff Scientist, Motorola

Customer Satisfaction is a common topic and theme, especially in the private business sector. However, the reality of developing a customer satisfaction culture remains an enigma for many, including large and small private businesses and in the public sector (particularly in North America). Once an enterprise realizes the importance of customer satisfaction to their overall bottom line, there are hands on universal strategies that can be utilized to achieve customer satisfaction. These universal strategies can be used by any enterprise, large or small, private or public, profit or non-profit.

Lambda Notes Book Review
by Dave Dyrck, Buffalo Chapter member

"Statistical Distributions", by Evans, Hastings, and Peacock, second edition, 170 pages, John Wiley & Sons, Inc., 1993.

A handy reference to thirty-nine discrete and continuous probability distributions, this work is certainly not casual reading. Although the first chapters cover some of the basics of probability and statistics, this work is also not intended for use as a student classroom text.

The work is, however, valuable to those who need to find, in one place, the definitions and properties of probability distributions such as the domain, parameters, pdf, CDF, inverse, moment generating function, survival function, hazard function, mean, variance, skewness, kurtosis, etc. Graphs of the pdf, CDF, and in many cases the hazard function are presented. Variate relationships are provided, along with equations for parameter estimation and random number generation. All of the common (and some of the marginally uncommon) probability distributions are included as well as the Dirichlet, logistic, Pareto, von-Mises, Laplace, and others.

As a technical reference, this work belongs on the bookshelf of anyone engaged in probabilistic analysis.

Note: Reviewed by D. A. Dyrck, Senior Reliability Engineer, Delphi Harrison Thermal Systems, ASQ-Certified Reliability Engineer, SRE, Buffalo Chapter, and holder of the Professional Certificate in Reliability and Quality Engineering from the University of Arizona.

"There are comparatively few engineering problems in which the data are known to within, say, 5%, hence it is a sheer waste of time for the engineer in practice to use the long complex methods when simple, close approximations can be used in a fraction of the time." --- John Goodman (Brit.)



Coefficient Of Variation
A Buffalo Chapter Technical Review
by Dave Dyrck

An interesting relationship exists between the shape parameter, b and the coefficient of variation, COV, of the two parameter Weibull distribution. Using the method of matching moments, it can be shown that:

COV = s/m = { [ G(1+2/b) / G2(1+1/b) ] -1}1/2 An approximate solution for b is given by Dr. Kececioglu, in his "Reliability and Life Testing Handbook", Vol. 1, pp. 424-430, as: b = COV -1.08 [ valid for 0.02 < COV < 1.5 ] A further simplification (not quite as accurate, but much easier to remember and to use) is: b = COV -1 = 1 / COV = m/s

This simplification underestimates the true shape by about only 10% at b = 3.5, about 5% at b = 2, and, obviously, 0% at b = 1, given that m and s are known.

Relationships exist between the shape parameters and the coefficients of variation, COV = s/m, of a number of commonly encountered probability distributions. These relationships can be used to assist in selecting candidate distributions for the modeling of data.

For the two parameter Weibull distribution:

COV = { [ G(1+2/b) / G2(1+1/b) ] -1}1/2 @ b -.926
b @ COV -1.08 [ valid for 0.02 < COV < 1.5 ]
scale parameter, h = m / G(1+1/b)
For the exponential distribution:
COV = 1Weibull shape, b = 1
For the Rayleigh distribution:
COV = [ (4/p) 1 ] 1/2 = .5227Weibull shape, b = 2
For the gamma distribution:
COV = b -1/2Gamma shape, b = COV 2
For the chi square distribution: COV = (2/n)
Shape, degrees of freedom, n = 2 COV 2
For the lognormal distribution: COV = ( exp s2 - 1 ) 1/2
Shape, standard deviation of the natural logarithms,
s = [ loge (COV 2 + 1 )]1/2
For the normal distribution:

Before selecting the normal distribution to model times to failure or times to repair data, (t), note that its domain of definition is - < t < +. This means, in theory, that a portion of the left tail of the normal probability distribution enters the negative region of t. Thus, P (t 0) < 1.00, which may not be appropriate for the situation.

The coefficient of variation, COV = s / m, can be used to find the probability of (t) being less than zero, or the reliability at age t = 0.

P (t < t1) = f (Z), where Z = (t1-m)/s
P (t < 0) = f (Z), where Z = (0-m)/s = -1/COV
P (t 0) = 1 - f (Z) = R (t = 0)

COV = s/mZ = -1/COVReliability, R (t = 0)
