Course detail
Fundamentals of Reliability in Electrical Engineering
FEKT-MPC-ZSEAcad. year: 2024/2025
The course deals with the issue of reliability, the basic concepts, the use of statistics in reliability calculations of reliability indicators. In addition, students learn the reliability models, backup systems and methods of reliability analysis. Another part of the course is devoted to the operating model and stress, degradation mechanisms in materials, elements and systems.
