This lends the procedure and the predictions derived from it a high level of credibility free from the bias of any individual supplier or service provider. SR-332 provides the only hardware reliability prediction procedure developed from the input and participation of a cross-section of major industrial companies. The Telcordia Reliability Prediction Procedure has a long and distinguished history of use within and outside the telecommunications industry. SR-332 provides all the tools needed for predicting device and unit hardware reliability. This prediction provides necessary input to system-level reliability modes for predicting expected downtime per year and system availability. NPRD-95, NPRD-2011, NPRD-2016, NSWC-98/LE1 Mechanics, Stress/Strength AnalysisĮasy to use built-in libraries containing over 400 000 widely used components by world leading manufacturers, include powerful decoding mechanism, user-defined libraries and enhanced search features.Reliability prediction is an important element in the process of selecting equipment. failure rate handbook had reduced DRAM failure rates by a factor of 24. (Chinese version of the MIL handbook), Telcordia SR-332. Mechanical Components Reliability Prediction Methods Telcordia SR-332 is a hardware reliability estimation methodology developed by. highly inaccurate.3,4 The updated version carries the same defi- ciencies from its predecessors. In Telcordia Issue 2, several new devices were introduced and the generic device failure rates were updated. Non-Operating Reliability: GJB/Z 108A-2006 Detailed, MIL-HDBK-217E-1 draft, RADC-TR-85-91, Reliability Toolkit (1995) Telcordia Issue 1 made minor changes and updated the device failure rates published in Bellcore TR-332. 02/95, FIDES Guide 2004, 2009, GJB/Z 299B Part Count, GJB/Z 299B Part Stress, GJB 299C Part Stress / Part Count, HDBK 217Plus, HDBK 217Plus-2015, HRD5 TELECOMM, IEC 62380, ITALTEL IRPH93, Operating Reliability: ALCATELб ANSI/VITA 51.1б BELLCORE Issue 5, 6, BRITISH TELECOM HRD4, HRD5, CNET RDF93 rev. RAM Commander Software supports the following Reliability Prediction methods:Įlectronic Components Reliability Prediction Methods RAM Commander is a modular application – modules may be used and purchased separately, or as an integrated RAMS toolkit. The Product Tree (BOM) forms the basis for the rest of the RAM Commander RAMS modules, which are interdependent and can be accessed by a one-click switch from Reliability Prediction to FMECA and Testability, RBD, FTA, etc. Imported from external applications or built manually in RAM Commander. In order to compare the predicted results from MIL-HBK-217 and Bellcore SR-332, we must convert the failure rate to the same units. The main block of RAM Commander is the Bill of Material, which can be either
