The aim of the course is to introduce students to the concept of reliability of simple and complex systems and make them familiar with probabilistic techniques for its computation and its use for the design of optimal maintenance policies.

Reliability: concept of reliability, time to failure distributions, failure rate, mean time to failure (MTTF), constant and time varying failure rates, failure types (early, random, wear‐out), bathtub curve, interaction between individual loads and system capacity.

Redundancy: active and standby redundant systems, combined series‐parallel systems, method of minimal paths and minimal cuts, reliability bounds.

Maintenance: system availability, preventive and corrective maintenance, periodic inspections for non detectable failures. Failure and maintenance interactions: computation of reliability, availability and MTTF by Markov analysis.

There are no prerequisite courses. It is recommended that students who are
interested in attending the course have completed successfully the following
