Advanced RBD Modeling Using State Change Triggers
A state change trigger is a powerful new modeling option in BlockSim 8 that can be used to model scenarios of cold standby with complex configurations, or scenarios where a failure of a component will result in the deactivation of other components in the same system. In this article, we will illustrate the use of state change triggers through a reliability modeling example of a mining plant.

Using Extrapolated Intervals in ALTA Degradation Analysis
In previous versions of ALTA, the degradation analysis results (i.e., extrapolated failure times) were available as point data, which do not fully reflect the variability of the estimated parameters. In Version 8, you have the option to extrapolate the failure times as interval censored data, which allows you to capture the uncertainty that comes with having only a few degradation measurements for each test unit. This article provides an example on how to use this new feature.

* ARS Europe Awards Issued - We formally congratulate the recipients of the Excellent Presentation Awards from the European Applied Reliability Symposium (ARS) in Warsaw last month. During this event, we had many engineers from various industries present on practical topics and the award winners were selected based on votes cast by Symposium attendees. These are the winners!

  • 1st Place (Gold) - Martin Shaw from Reliability Solutions for his presentation on "Predicting Field Failure Rate from Production Process Yield Data Using Real Life LCD TV Production Data."

  • 2nd Place (Silver) - Albertyn Barnard from Lambda Consulting for his presentation on "Why You Cannot Predict Electronic Product Reliability."

  • 3rd Place (Bronze) - Amnon Ganot from GERTRON RAMS Consulting Services for his presentation on "Prerequisites for a Comprehensive and Successful FMEA."

Thank you for your hard work and congratulations for garnering the winning votes!

* Call for Presenters for ARS India - The ARS committee is currently soliciting presenters for the 2012 ARS, India, which will be held in Chennai, India on October 10 - 12, 2012.
