Using the New Change Log Utility in Xfmea or RCM++
With the release of Version 4, ReliaSoft has added Change Log functionality to the Xfmea and RCM++ software. This will be of use to organizations that are under a regulatory or other requirement to strictly control and track modifications to existing FMEA or RCM analyses. The functionality has been designed to be flexible enough to fit procedures and requirements that may vary by organization. This article describes one way that you might use the softwares new Change Log features to manage and track revisions to a particular analysis.

How Long Should You Burn In a System?
Burn-in testing is an important reliability technique that can be used to improve the population of a product before shipping. It relies on weeding out weak units by operating all units for a predetermined period of time. The units that survive are considered to be appropriate for shipping, while failed units are discarded. Some applications call for burning in a whole system made of various components instead of burning in the components individually. This article discusses good burn-in strategies, depending on the type of the system's failure rate behavior, using BlockSim.

Xfmea 4 and RCM++ 4 Soon to Be Released - ReliaSoft is about to release new versions of Xfmea (Failure Modes and Criticality Analysis) and RCM++ (Reliability Centered Maintenance). Many significant and exciting enhancements have been added to the software's features and functionality, including:

  • Change Log
    The software now allows 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. You can also use the Record Change Log window to view (and export) the history of changes that have been made to a particular record.

  • Design Review Based on Failure Mode (DRBFM)
    The software now provides an integrated utility to support Design Review Based on Failure Mode (DRBFM) analysis, which is used in many industries to evaluate proposed changes to an existing design. By attaching the DRBFM to an existing FMEA, you will be able to transfer relevant function descriptions from the FMEA, analyze the concerns that may have been introduced by the change and then transfer selected issues back to the original FMEA, if applicable.

These and other new features, such as the ability to create customized tooltips for worksheet columns and export data as a fault tree in BlockSim FTI, are described at

* Lambda Predict Version 2 Upgrade - ReliaSoft is proud to announce the upcoming release of Lambda Predict Version 2. Lambda Predict 2 supports all of the major standards for reliability prediction analysis, including MIL-HDBK-217, Bellcore, NSWC-98, China 299B and RDF 2000. The software provides extensive component libraries, failure rate prediction results, plots, print-ready reports and more. Some of Version 2's significant enhancements to the software's features and functionality are listed below:
  • Derating Analysis
    Derating is the selection and application of parts and materials so that the applied stress is less than rated for a specific application. You can now apply a published or user-defined derating standard to your MIL-217, Bellcore or RDF 2000 system. Available published derating standards include NAVSEA-TE000-AB-GTP-010, MIL-STD-975M (NASA), MIL-STD-1547 and Naval Air System Command AS-4613 Classes A, B and C.

  • Other Time-Saving Enhancements
    The new Library Browse window allows you to browse for specific components in libraries and add them to your Lambda Predict analyses. You can also now create and manage "Grid View Templates" that can be used to automatically configure the grid to fit your saved preferences.
