Course abstract

The aim of study course - differential calculus of functions of several variables, graphical solution of linear programming problems, simplex method, transportation problem, basics of mathematical game theory are considered. The study course provides an understanding of modern concepts and problems of mathematical modeling. The study course promotes mathematical thinking, looks at different applications of mathematics in engineering.

Learning outcomes and their assessment

By the successful completion of this study course, students will have
1. knowledge of the differentiation of functions of several variables and their applications, methods for solving linear programming problems, transportation problems and mathematical game problems.. Knowledge is assessed during the exam, practical and independent works.
2. skills to perform necessary calculations and operations, understanding of relevant concepts and regularities. Skills are assessed during exam, practical and independent works.
3. Competence to perform intermediate results of calculations and professional evaluation and interpretation of final results. Competences are assessed during exam and practical work.

Description of the organization and tasks of students’ independent work

The following independent works must be completed:
Independent work 1: Differentiation of Functions of Several Variables.
Independent work 2: Operations Research.

Criteria for Evaluating Learning Outcomes

Students take a written exam (80% practical tasks, 20% theoretical questions) at the time indicated by the lecturer if all independent works have been passed (all tasks have been completed correctly). Independent works that have not been credited in time can be defended at the times indicated by the teaching staff.
