Learning outcomes of the course unit

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.

Prerequisites

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

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Graded course-unit credit requirements: elaborations of project of system reliability and real product process quality control; evaluation according to results of personal project.

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.

Specification of controlled education, way of implementation and compensation for absences
