Truncation of the Integral Used in the Comparison Wizard in Weibull++: Part II
In the July 2011 issue of HotWire, the Hot Topics article used simulations in RENO to illustrate the results of the Comparison Wizard in Weibull++ and study the effect of the upper limit in the calculation to the output of the comparison. In this article, we will provide an analytical explanation of the results.

Reliability Basics
Using RENO to Examine Interval Width
Sometimes when making a prediction of item life, the amount of usage of the item, such as the number of miles a car was driven or the number of prints a copier produced, is the variable of interest (rather than the time the product was in service). Typically, it is known when each item was put into service, so the time in the field for each unit can be calculated. If a failure occurs during the warranty period, the item is returned for repair or replacement and the usage of that item can be recorded. However, if the item does not fail, the amount of usage it has accumulated during its time in service is often unknown. The usage format warranty folio in Weibull++ has a built-in method of estimating the usage of non-failed items based on the time the items spent in the field and a user-specified usage distribution. With this feature, the user is asked to define an interval width that is used when calculating the usage values assigned to the suspended units. This article presents a simulation in RENO that illustrates the effect of changing the interval width on the way usage values are assigned to the suspended units in the Weibull++ usage format warranty folio.

Tool Tips
  • How can I speed up the data entry process in Weibull++ and ALTA?
  • In Xfmea 5 and RCM++ 5 why is the Project Creator field important and how do I change the person assigned to this user role?

Hot News
* Photovoltaic R&D Donation - ReliaSoft is pleased to announce its support of the "Photovoltaic Environmental Performance and Reliability for the Arizona-Wide Electric Grid" (PEPER) program. The research and development project will be carried out by Arizona State University in collaboration with the University of Arizona. ReliaSoft has donated licenses of Weibull++, ALTA PRO, BlockSim, RGA and Xfmea to ASU. The applications will be installed in the newly created ASU Photovoltaic Reliability Laboratory where researchers will be able to better model, analyze and predict the reliability of components and systems in the solar energy sector. ReliaSoft Corporation looks forward to working closely with Arizona State University and the University of Arizona on this R&D investment in Arizona's future.
* New City Selected - The ARS planning committee has selected the festive city of New Orleans, Louisiana for the 2012 Applied Reliability Symposium in North America! The event will be held June 13 - 15, 2012. For those of you interested in presenting, the deadline for submitting a presentation proposal is December 7, 2011. Additional details are posted online at: http://www.ARSymposium.org/northamerica/index.htm.
* 2011 ARS Coming Up Fast for India and Singapore!!! - Next month the Applied Reliability Symposium will be hosted in two cities! Each event will provide a forum for industry experts and reliability practitioners to discuss the practical application of reliability principles. Real world challenges and the success stories associated with them will be the primary focus. The first event will be held in Bangalore, India on October 12 – 14, 2011. The Asia Pacific event will be the week after in Singapore on October 19 - 21, 2011. Don't miss these rapidly approaching symposiums if you are in the region.
