Course abstract

Students study the Operations Research methods for decision-making, acquire practical skills in Mathematical Programming (Linear Programming, Integer Programming and Integer Nonlinear Programming), modelling with MS Excel optimization tool Solver, Project Management software MS Office Project and a comparison of alternatives by The Analytic Hierarchy Process.

Learning outcomes and their assessment

After completing the course student will have:
Knowledge about Operations Research methods for decision planning and making management with computer (tests, home works and practical works);
Skills - build the mathematical models with MS Excel and MS Project for operations research and decision making with AHP (tests, home works and practical works);
Competence – knowledge and ability for optimal and environmental safety decision planning and making process with Information Technologies (tests, home works and practical works).

Requirements for awarding credit points

Successfully passed the formal test with a grade at least 40% of the course total score.

Description of the organization and tasks of students’ independent work

Tasks for the independent work are included in e-studies (
There is one independent and individual work in the semester.

Criteria for Evaluating Learning Outcomes

1. The formal test cumulative assessment depends on two tests (70 %) and independent individual work (30 %) ratings.
2. Students who are mostly studying independently, or wish to improve the cumulative assessment take the written formal test (70 %). Independent individual work assessment (30 %) will also be taken into account.
