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.

Learning outcomes and their assessment

1. Knowledge - the student knows the elements of automation and their application in automated industrial engineering, production, technological processes and the specifics of production automation, methods of analysis, synthesis, modelling, design and calculation of automation equipment and processes - lectures and theoretical test.
2. Skills - able to apply automated industrial engineering , production , technological processes (TP) and product conformity assessment methods is able to evaluate, substantiate and select the required level of TP automation and reasonably select the components of production technological processes, optimal operating modes, compile, connect and experimentally test automation and electric drive circuits, perform calculations and evaluate process quality - laboratory work.

3. Competence - selection of the principle and optimal modes of automated process and equipment management, evaluation of performance quality and justification of improvement solutions - developed and defended independent work, test.

Requirements for awarding credit points

The student is admitted to the written test only if the laboratory works has been worked out, control tests №1 and №2 is approved and independent work is accepted.
Exam consists of three questions:
1. The question of automation theory;
2. The question of practical work;

3. The question of the working principle of operation of a given TP automation and TP functional scheme.

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 evaluation of the written test consists of the correct answer to each test question. The correct answer may have minor shortcomings or minor errors. The answer can be correct, comprehensive, and broad, to each question, correct with minor flaws or errors, correct answer that contains only basic concepts without explanation, or contains material errors. If there is no answer, the answer is wrong, there are very gross significant errors in the answer, then written test not passed.

Assessment of test consist of the following parts – practical and homework (4), homework presentation (2), defence (2). To get 9 – 10 assessment – student can choose additional exercises.
