Dont Let Your Event/Maintenance Log Data Go to Waste
Companies are increasingly relying on information to run their businesses and stay competitive. More aggressive productivity goals and globalization needs are putting higher pressure on companies to increase the efficiency and availability of their assets. In this competitive environment, one companys downtime can become another company's opportunity. Obtaining relevant data about the failures and repairs of assets is central to achieving company goals.

One very valuable kind of data that is collected in the manufacturing, process, oil, machine tools and communication industries is the log of failures and repairs of physical assets such as machines, airplanes, computers, servers, trucks and oil refineries. This information can provide many insights about failure modes, outages, their frequencies, the repair duration, uptime/downtime and availability. It can aid in gaining knowledge required for critical business performance improvements.

The volume of this type of data can become very large and the task of extracting useful and concise information can also become cumbersome. This article highlights some of the functionalities of Weibull++ 7 that can be utilized to facilitate the processing of event or maintenance logs that your company might be keeping track of.

Reliability Basics

How to Simplify Complex RBDs with a Commonly Used Distribution
System reliability analysis relies on deriving a system reliability equation (cumulative density function, cdf, and/or probability density function, pdf) from the Reliability Block Diagram (RBD) of a system. The derived equations can be used to calculate various reliability metrics. The pdf and cdf can easily become complex equations as the RBDs become more complex and the distributions of the blocks in the RBDs become more varied.

Often, reliability analysts need to approximate a system's RBD with a simple distribution. In this article, we explain an approach for simplifying RBDs with a simple representative common distribution using BlockSim 6 and Weibull++ 7.

Hot News
* New Xfmea and RCM++ Features Coming - ReliaSoft will soon be releasing a new version of Xfmea and RCM++ that provides many enhancements and exciting new features. One of these key features will allow authorized users to activate a Change Log for a particular analysis, which records a version history and a log of every change to the original analysis. The software will also provide an integrated utility to support Design Review Based on Failure Mode (DRBFM) analysis, which is used in the automotive and other industries to evaluate proposed changes to an existing design. For more information on these and other new features that will be available in the Version 4 release, see http://Xfmea.ReliaSoft.com/version4.htm.
* ReliaSoft at ESREL 2006 - We would like to thank everyone who stopped by our booth at the 2006 European Safety and Reliability Association Conference (ESREL) last month. It was great seeing our old friends and making new ones. We look forward to hearing more from you over the course of the year!

Now is your opportunity to plan all of your 2007 training in advance before our classes fill up!
* New Class Added!  -ReliaSoft has recently added RS 490 Introduction to Standards Based Reliability Prediction and Lambda Predict to our course catalog. This two-day course introduces standards based reliability prediction analysis with hands-on training in the use of ReliaSoft's Lambda Predict software. The emphasis is on how to maximize the benefits of Lambda Predict and its wide range of capabilities. The course covers the three most commonly used Reliability prediction standards (MIL-HDBK-217, Bellcore and NSWC Mechanical) with brief coverage of RDF 2000 and China 299B. The first publicly scheduled event is coming up soon (November 30 - December 1, 2006)! For more information, please visit http://Seminars.ReliaSoft.com/gencourses/rs490.htm.
