Course detail

Reliability and Quality

FEKT-MKC-SAJAcad. year: 2024/2025

The main goal of course deals with takes part in the issues of reliability of systems with independent and dependent elements and using statistical methods in reliability. The students will also learn processes of back-up, reliability management methods, breakdowns preventions and fault-tolerant systems creating. In addition, the course deals with the implementation of quality systems in electrical engineering and problems of quality assurance approaches.
