ReliaSoft Lambda Predict

Lambda Predict makes it easy to build system configurations for analysis based on the MIL-HDBK-217-F (MIL-217), Bellcore/Telcordia or NSWC Mechanical reliability prediction standards. The software provides a complete array of calculated results for your analyses (failure rate predictions, MTBF predictions, etc.) along with graphical charts and customizable reports. Lambda Predict offers a full set of supporting tools, including a reliability allocation utility, derating analysis and the ability to transfer and manage your data via flexible import/export utilities. The software also provides exclusive access to the PartLibraries.org Web portal, which allows users to search and import parts data from MIL-M-38510, EPRD-97 or NPRD-95 (free to all users) as well as more than 300,000 specific commercial electronic components (yearly subscription required).

The Lambda Predict software provides a comprehensive platform for building and analyzing systems in accordance with published reliability prediction standards. Some of the many applications for using standards based reliability prediction techniques and ReliaSoft’s Lambda Predict software include the ability to:

• Obtain an initial indication of whether a design will be able to meet reliability objectives and identify potential problem areas early in development.
• Compare design alternatives and/or trade-off system design factors.
• Consider environmental and other stress factors that have a significant impact on system performance yet may otherwise be overlooked.

The Lambda Predict software facilitates every step of the standards based reliability prediction analysis process, with user-friendly capabilities designed to make it easy for you to:

• Build the system configuration (“from scratch” or by importing data from “Bill of Materials” files, predefined part libraries or other outside sources)
• Define component characteristics and operating conditions, with the choice of four different “Views” to facilitate data entry
• Calculate results (Pi Factors, Failure Rates, MTBFs, etc.) at any level within the configuration
• Use graphical plots/charts to visualize and present analysis results
• Generate print-ready reports to support decision-making and disseminate knowledge

Lambda Predict also makes it easy to perform derating analysis for your systems. When you select from the available published derating standards or define your own, the software provides a visual indication of each item’s derating status and allows you to drill down for more detailed analysis information and plots. The following standards are available: NAVSEA-TE000-AB-GTP-010, MIL-STD-975M (NASA), MIL-STD-1547, Naval Air System Command AS-4613 and ECSS-Q-30-11-A.

The Allocation utility provides a choice of five allocation models that can be used to logically apportion the product design reliability into lower level design criteria such that the cumulative reliability still meets the requirements. The available models are: Equal Allocation, AGREE Allocation, Feasibility of Objective Allocation, ARINC Apportionment Technique and Repairable Systems Allocation.

Lambda Predict stores your analysis information in relational database files, which makes it possible for you to take advantage of many useful data management capabilities. For example, the software provides a flexible tool for finding and re-using data from existing analyses or libraries. You also have the option to easily duplicate or transfer data using import/export or copy/paste.
