Dependability and safety definition. Dependability and safety as a part of quality. Safety of technical objects - definition, legislature, risk analysis, risk management. Dependability managament, control and assurance. Dependability of technical objects during his life cycle. Performance measures of safety, durability, reliability, maintainability and availability, its probability and statistical models. Qualitative and quantitative methods of

dependability analysis (FMEA, FTA, RBD, MA, PC etc.), reliability prediction of systems. Means of systems dependability increasing. Evaluation and control of operational dependability. Dependability information systems


Submission of solution given task, passing the written test.

Syllabus of lectures:
