Reliability, Availability and Maintainability (RAM) Analysis


To enable students to apply appropriate ARM methodologies to projects, ensuring that ARM is included within the design and that ARM targets are met.  The module also discusses the concept of critical and life-limited items and the use of reliability-centred maintenance strategies to reduce maintenance costs.  Finally the module considers the trade-offs between ARM and safety requirements, as well as discussing how ARM shortfalls may be addressed.


At the end of the course you will be able to

  1. Identify and apply the analysis methodologies to systems and sub-systems, including both design and operation restrictions, to determine the Availability, Reliability and Maintainability of these Systems.
  2. Critically review and balance the requirements of the design for ARM and safety.
  3. Logically deduce how ARM results for a system may be improved.
