Fundamentals of Dependability Theory
FSI-RZT Acad. year: 2020/2021 Winter semester
The course is concerned with the following topics: Significance of the quality (and its most important parameter – dependability) for successful use of the product on the market.
Definition of the basic terms. Survey of the most important methods for securing dependability of technical systems. Application in the assessment of the limit states of structures – interference theory, approximation methods FORM and SORM, simulation-based methods. Operational dependability.

Learning outcomes of the course unit
Students will be acquainted with modern methods of dependability assessment of products in various periods of their lifetime. The main attention is paid to the use of the Theory of dependability in limit states of structures and to the assessment of their reliability and durability from the probability point of view.
Prerequisites
Basic knowledge of probability theory, Boole´s algebra and mathematical statistics.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
Graded course-unit credit requirements: active participation in seminars, well-elaborated assignments, solving additional assignments due to absence. Seminar tutor will specify these conditions in the first week of semester.
Course unit credist will be awarded based on evaluation of the project.
Aims
The objective of the course is to make students familiar with elementary terms in the Theory of dependability and with the most significant methods of active dependability provision of structures in their life periods such as research, development, production and utilization. The emphasis is put on most significant characters, i.e. as safety, durability and reliability in the probability conception.
Specification of controlled education, way of implementation and compensation for absences
Attendance at practical training is obligatory. More absences are compensated by additional assignments according to the instructions of the tutor.
