What is RAM
• RAM refers to Reliability, Availability and Maintainability.
• Reliability is the probability of survival after the unit/system operates for a certain period
of time (e.g. a unit has a 95% probability of survival after 8000 hours).
• Reliability defines the failure frequency and determines the uptime patterns.
• Maintainability describes how soon the unit/system can be repaired, which determines
the downtime patterns.
• Availability is the percentage of uptime over the time horizon, and is determined by
reliability and maintainability.

Why use RAM as a tool
• RAM has a direct impact on profit through lost production and maintenance costs. The
main objectives of RAM analysis are to increase system productivity, increase the
overall profit, as well as reduce the total life cycle cost — which includes lost production
cost, maintenance cost, operating cost, etc.
