Course detail

Reliability in production

FP-BsvPAcad. year: 2020/2021

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.

Learning outcomes of the course unit

The student is able to:
- define the basic concepts of reliability,
- describe methods of reliability analysis systems,
- explain the methods of reliability,
- explain the issue of risk in production,
- calculate selected indicators of system reliability.


The subject knowledge on the Bachelor´s degree level is requested.
