Learning outcomes
|
The goal of this subject is to introduce basics theory of dependability and risk to students. The fundamental gist of those science field is proper terminology, that is followed by the most common dependability parameters and ways of its calculation. Subject accents practical application of attained knowledge and umbrella point of view in such a multidisciplinary activity as the risk management is.
Student will acquire the basic overview about commonly used dependability parameters of technical systems, about the methods used to its evaluation and about possibilities of using these parameters e.g. for the maintenance planning.
