Course abstract

The aim of the course is to prepares highly qualified, competitive and competent specialists for the analysis, control, regulation and management of automated technological processes (TP) in accordance with the requirements of automated industrial engineering. During the study process, students acquire knowledge, skills and competencies that correspond to the paradigms of modern engineering and management science. During the study process, students get acquainted with the principles of computer control of production, learn the principles of TP quality and efficiency evaluation and management, which include the methods used by the world's leading industrial companies.

Requirements for awarding credit points

A written theoretical test has been passed on time, an independent work has been developed and defended, and 2 tests have been passed.

Description of the organization and tasks of students’ independent work

The student prepares a report or a presentation on a freely chosen topic of TP automation, including control schemes, diagrams and engineering calculations. Independent work can be performed using computer programs EDrawMax, SCADA, TRACE MODE 6, etc.

Criteria for Evaluating Learning Outcomes

The assessment of the study course consists of two control tests and an assessment of independent work. Independent work not submitted on time or an incomplete or unsuccessfully completed test will not be assessed. The assessment consists of the following parts - practical and homework performance (4), independent homework presentation (2), public defense (2).
