Using Weibull++ 7 and Monte Carlo Simulation for
Probabilistic design is a
methodology aimed at producing robust and reliable products. A common
mistake made by design engineers is not considering variations in the
factors that affect the reliability or performance of their product and
instead using only the nominal or mean values of these factors. By
understanding the probability distributions of the design parameters,
environmental usage profile and manufacturing variations, the design
engineer can design for a specific reliability or quality level by producing
designs that are robust to variations.

The new version of Weibull++,
version 7, introduces four more life distributions in addition to the
Weibull-Bayesian distribution discussed in the previous
HotWire. These are the Gumbel, logistic, loglogistic and Gamma
distributions. In this article, we present an overview of the new
distributions and discuss some of their characteristics and applications.

International Applied Reliability Symposium, Orlando 2006 -
Please mark your calendars and begin thinking about attending the
2006 International Applied Reliability Symposium next June in
Orlando, FL. General information is available at
The symposium has been booked for the Sheraton World Resort, which
is walking distance from Sea World and 5 minutes away from Walt
Disney World and Universal Studios. Registrations are currently
being accepted at
Presentations are still being
received; however, the deadline for presentation proposal
submissions is October 31, 2005. Presentations will be accepted on
the basis of the proposal. Because of the applied nature of the
Symposium, presenters are asked to submit materials in presentation
format only (i.e.
PowerPoint - see Template at
http://www.arsymposium.org/present.htm). An accompanying paper is
not required. 60 minutes have been allocated for each presentation
with 10 minutes of questions for a total of 1 hour and 10 minutes
per session. Presenters receive complimentary registration for the
2006 Training Schedule Posted
officially posted next year's training schedule for those of you who
need to begin planning your continuing education. Classes range from
training on up to some very challenging yet fun advanced course
work. Next year's handy training matrix is posted at
