FUNDAMENTALS OF RELIABILITY IN ELECTRICAL ENGINEERING
ÚSI-RTSEVAcad. year: 2020/2021
The course deals with the issue of reliability, the basic concepts, and the use of statistics in reliability and the calculation of reliability indicators. In addition, students are familiarised with the reliability models, backup systems and methods of reliability analysis. Another part of the course is devoted to operating and model stress, as well as degradation mechanisms in materials, elements and systems.
Learning outcomes of the course unit
The student will be able to:
- define the basic concepts of reliability,
- describe methods of analyzing the reliability of systems,
- explain the methods of reliability management,
- explain the issue of risk in production,
- calculate selected indicators of system reliability.
Knowledge of the subject at the Bachelor´s degree level is required.

Planned learning activities and teaching methods
The course is taught via lectures and sessions in computer laboratories and practical
laboratories. Students must submit a single project/assignment during the course.
Assesment methods and criteria linked to learning outcomes
up to 20 points from the seminars (the student will receive these points for their individual work in the field of reliability, and its presentation).
up to 80 points from a written examination.
The test focuses on the reliability issues discussed in the lectures and seminars.
