Course detail
Reliability of Structures
FSI-RSTAcad. year: 2024/2025
The aims of the tutorial are the active methods of system reliability design, analysis and testing, operational availability performance, and analysis of the influencing factors. The main emphasis is put on reliability performance, maintainability performance and maintenance support performance. The economic aspects of reliability are taken into account too, especially the economic optimisation of reliability factors is stressed in the course. Detailed explanation system reliability theory, basic statistical concepts, methods of reliability analysis, reliability allocation, introduction to reparable systems, reliability information systems, interference theory and methods of reliability testing are treated in lectures. Failure reporting, analysis and corrective action systems and their usefulness for reliability are explained.

Rules for evaluation and completion of the course
Classified accreditation is in the written form; consists theoretical questions a problems for solution.
Attendence is required. One absence can be compensated by elaboration of substitute tasks. Longer absence is compensated by special tasks according to instructions of the tutor.
Seminar credits are granted under the condition of active presence in the seminars, good results of seminar tests of basic knowledge, solution of additional tasks in case of longer excusable absence. Seminar tutor will specify concrete form of these conditions in the first week of semester.
Aims
The students will acquire modern computational and analytical methods for active creation and verification dependabilitity of products in all periods their lifetime. They will be able operate with international standards (EU standards) which styles liability suppliers of products and services to ensure quality, reliability and safety.
