System reliability , reliable systems

Reliability theory is an indispensable element in modern maintenance processes. The reliability of basic components and systems can be modelled by probability calculations and mathematical/ statistical tools.

We use examples to demonstrate reliability calculations in a wide range from simple basic components up to spare complex systems. We depict a number of types
of sparing (cold, hot and spare items with reduced capacity), their respective benefits and drawbacks.
The most wellknown stand-by reserve system is called the k/n system. The reliability values of the equipment installed at the Duna Refinery’s functional locations serve as real-life values in relation to reliability.
