The subject is taught in Polish

System safety

The aim of the course is to develop an understanding of the role and scope of requirements and associated guarantees for safety-related systems, to acquire knowledge of basic methods and techniques for the design and analysis of such systems, and to practice risk analysis techniques for a selected safety-related system.

The knowledge and skills acquired in this subject form the basis for analytical work on the applications of IT systems in target environments with a significant level of safety threats.

Lecture

The scope of issues covered includes:

  • The concept of a safety-related system; examples
  • Design principles;
  • Redundancy and its impact on reliability and safety;
  • The principle of diversity, its application to software and its impact on reliability and safety;
  • Risk analysis and risk matrix;
  • IEC 61508 standard and the ALARP principle;
  • The concept of Safety Integrity Levels (SIL);
  • The role of human error;
  • Assurance and safety cases: objectives, scope, supporting tools;
  • Safety life cycle;
  • Hazard identification methods; PHA, HAZOP;
  • Hazard analysis methods; FTA, ETA, FMEA, FMECA, CCA.

We encourage those interested in the subject matter to choose a specialization Information Systems Engineering. 

Project

As part of the project, students work in groups. Groups are provided with a description of a safety-related system and complete three tasks: task 1 involves identifying threats (hazards) and related scenarios; task 2 involves analyzing and assessing the risks associated with the identified threats; and task 3 involves constructing a case for system safety by planning remedial actions for selected threats. During task 3, groups receive access to the PREMIS system, which supports the development and evaluation of system credibility arguments. The project concludes with joint workshops, during which groups present their findings and share their experiences.
