RWB Training Course

This course provides an introduction to the standard methods applied in reliability and safety studies. This workshop course utilises the Reliability Workbench computer program.

Methods covered are:

  • Failure Rate Prediction Standards (MIL-217, Telcordia TR/SR-332, NSWC, IEC TR 62380, GJB/z 299B and C, 217Plus). These standards provide different methods of calculating the failure rate of a component based on its construction and usage. Training also covers usage of the program, how to use the library facility, and other special features of the Prediction module.
  • Failure Mode Effects and Criticality Analysis (FMECA). This is a commonly used technique for evaluating the different failure modes of a component, and how they affect the system at higher levels. It can also be used to determine what percentage of failures are critical. This part of the course covers the usage of the program and how to switch amongst the different standards for FMECA/FMEA analysis.
  • ¬†Reliability Allocation. This method, useful during the design stage, helps set reliability goals for individual sub-systems and equipment based on an overall reliability target and subsystem complexity or redundancy levels.
  • Reliability Block Diagram Analysis. This method of reliability analysis consists of diagrams that indicate how component failures interact to produce system failure. This can take into account redundancy and voting arrangements, where n out of m components are required to be working for success. The course covers usage of the RBD module.
  • Weibull Analysis. Using historical data to predict a failure rate curve for a given failure or repair process. The Weibull module integrates with RBD to allow users to base block failure rates on real-world data.
  • Reliability Growth. Similar to the Weibull module, this module uses field or lab test data to look for evidence of positive or negative growth.
  • Reporting. Using Isograph’s Report Designer to create and publish text column, text row, graph and diagram reports.

In addition to teaching the different methods of reliability analysis, this course also teaches usage of each Reliability Workbench module individually as well as how to share data between the modules. Combine this course with Introduction to Fault Tree Analysis to provide a complete introduction to all modules of Reliability Workbench.
