Summary of the subject: The educational discipline "Modern methods of ensuring the reliability of information systems" is an important part of the training of specialists and provides training in the field of analysis, synthesis and optimization of information systems. This discipline should form the future specialist's understanding of the essence of reliability design and the role of reliability and functional safety as defining characteristics of the functioning of information systems.
Опис: The concept of reliable design of information systems. Indicators of reliability of information systems. Methods for determining the reliability of IS. Ensuring the reliability of information systems at the design stage of their structure. Ensuring the reliability of information systems at the stage of operation. Designing algorithms for the behavior of information systems. Indicators of functional security of information systems. Evaluation of functional safety indicators at the stage of system engineering design of information systems.
Assessment methods and criteria: During training, students perform individual project tasks in laboratory classes, the solution of which requires thorough theoretical training in accordance with this program. Protecting project tasks motivates students to better study and develop communication skills. Evaluating the results of individual tasks is a form of ongoing control. Final tests are planned for each topic using the Virtual Learning Environment of Lviv Polytechnic. Semester examination control is conducted in writing on the basis of a set of examination tickets, which is approved at a department meeting.
Критерії оцінювання результатів навчання: - current control: written reports on laboratory work performed (40%);
- final control: control measure (exam) in written and oral form (60%).
