Basic Reliability Prediction Software

Basic Reliability Prediction (MTBF Calculation)

RAM Commander software prediction module is a reliability tool providing everything necessary for primary reliability prediction (MTBF or failure rate prediction/calculation) based on one of the prediction models for electronic and mechanical equipment.
It contains more than 30 reliability prediction methods, including the latest methods like FIDES  2009 and 217 Plus:

RAM Commander's reliability module supports 'one-click' automatic switch between different prediction methods.
Each method requires a set of component parameters which should be defined in order to calculate its reliability:

RAM Commander makes management of these complex data much easier and more convenient, by providing a comprehensive set of reliability libraries.

Components Library

RAM Commander contains built-in electronic components library. ALD supplies the library containing hundreds of thousands (a total number of records is currently 500,000 and contnues growing) of widely used electronic components by the world leading manufacturers. The RAM Commander team continually updates this library adding more manufacturers' data on a monthly basis.

Customers also may update the library - both manually and by importing components data.

Part Number Recognition
Leading manufacturers use special algorithms for naming their parts. RAM Commander implements these algorithms for the opposite direction in order to get reliability data for each Part Number. Our reliability software supports algorithms for decoding Part Numbers of passive components (Resistors and Capacitors) of the following manufacturers:
AVX, ATC, Bourns, Cal-chip, DALE, Hitano, Garrett, IRC, Johanson, Kemet, KOA, Kyocera, Mallory, Meritek, Murata, MSI, NIC, Nichicon, Novacap, Samsung, Siemens, Syfer, OhmCraft, Paccom, Philips, Phycomp, Ralec, ROEDERST, TDK, TaiyoYuden, Vishay, Roedenstein, Vitramon, Yageo.

GPRD Library
General Part Reliability Data (GPRD) is an additional reliability data library available for users. It is used to store manufacturers' provided or field reliability data (obtained from FRACAS or another source).

Reliability prediction methods described above, reliability libraries and convenient project tree building and management utilities makes RAM Commander reliability prediction module a must-have tool for reliability engineering.

RAM Commander allows generating various reports with a breakdown of MTBF figures per system, unit, board and component levels as a result of reliability prediction:

Assembly Composite Report

Obtained failure rates are then used in reliability and availability analysis using Temperature Curve, Mission Profile, Pareto and other tools - see Reliability & Availability Analysis Software Module.
