 Study Objective:

The aim will be to teach students to create and solve mathematical models of realworld (primarily economic) systems with the emphasis on finding optimal decisions according to selected criteria. Students will be acquainted with the areas of linear programming and addressing general or integer linear programming algorithm of dual simplex/simplex algorithm. They will also be familiar with the problems of transport tasks in order to minimize the transport costs and the assignment problem with the application of the Hungarian method to find the optimal assignment.
It will also be the aim to acquaint students with the basic concepts of graph theory, in particular representations of graphs, charts, skeletons search paths or throughput in the chart, graph algorithms in taskoriented and nonoriented charts. The issue will also be part of the network analysis, in particular the application of CPM and PERT method.
At the end, students will be introduced to an introduction to inventory theory, respectively inventory management models.
