Optimalization of distribution process in trading company

The thesis deals with distribution problems and their methods for their solution. They belong to one of the most often used optimization models in practice. The thesis describes background for using modelling support systems LINGO and MPL for Windows. The modelling languages allow solving all problems described in the theoretical part including the travelling salesman problem and the vehicle routing problem. There are described basic heuristic methods for problems with higher number of variables in this work as well. The thesis includes the description of a real situation for which it is possible to apply travelling salesman problem or vehicle routing problem models. It is a complex problem which cannot be solved by exact methods but heuristic methods must be used. The problem is going to be solved by means of MS Excel together with Visual Basic for Applications using the heuristic method of nearest neighbour
