SR-332, Reliability Prediction Procedure for Electronic Equipment [1] HRD-4 (British Telecom) SR-1171, Methods and Procedures for System Reliability Analysis [2] and many others; These "standards" produce different results, often by a factor of more than two, for the same modelled system.
RAMP Simulation Software for Modelling Reliability, Availability and Maintainability (RAM) is a computer software application developed by WS Atkins specifically for the assessment of the reliability, availability, maintainability and productivity characteristics of complex systems that would otherwise prove too difficult, cost too much or take too long to study analytically.
The Mil-HDBK-217 reliability calculator manual in combination with RelCalc software (or other comparable tool) enables MTBF reliability rates to be predicted based on design. A concept which is closely related to MTBF, and is important in the computations involving MTBF, is the mean down time (MDT). MDT can be defined as mean time which the ...
Reliability prediction can be used to size spare populations. Provide necessary input to system-level reliability models. System-level reliability models can subsequently be used to predict, for example, frequency of system outages in steady-state, frequency of system outages during early life, expected downtime per year, and system availability.
Stress–strength analysis is the analysis of the strength of the materials and the interference of the stresses placed on the materials, where "materials" is not necessarily the raw goods or parts, but can be an entire system. Stress-Strength Analysis is a tool used in reliability engineering.
Depending on the types of analysis run and the data entered to create the analysis, reports can run between 20 and over 200 pages in length. The semiconductor module is in compliance with SAE ARP 6338 [ 8 ] and is being considered as a replacement to traditional empirical reliability prediction methods (MIL-HDBK-217, [ 9 ] Telcordia SR-332 ...
THERP is a first-generation methodology, which means that its procedures follow the way conventional reliability analysis models a machine. [3] The technique was developed in the Sandia Laboratories for the US Nuclear Regulatory Commission. [4] Its primary author is Swain, who developed the THERP methodology gradually over a lengthy period. [2]
A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
