Entry knowledge

Mastering basic and advanced methods of probability theory and mathematical statistics is assumed.

Rules for evaluation and completion of the course

Credit conditions: project elaboration.
Conditions for passing the exam: mastering practical examples on a PC.
Attendance at seminars is controlled and the teacher decides on the compensation for absences.

Aims

The course objective is to make students majoring in Mathematical Engineering acquainted with methods of the reliability theory for modelling and assessing technical systems reliability, with methods of mathematical statistics used for quality control of processing, and with a personal project solution using statistical software.
Students acquire needed knowledge from the important area of the reliability theory and quality control, which will enable them using a PC model and determine important quality characteristics of technical systems and processes on the basis of statistical data.
