Optimalization of mixed goods pickup and delivery

This thesis is focused on the use of linear models in the real world. Its main aim is to devise a mathematical model for a specific problem which is repeatedly encountered by the company Pospíchal s.r.o. and also to find an optimal solution with the help of this model. The thesis is based on basic distribution problems, such as the travelling salesman problem or the vehicle routing problem, which I subsequently modify into the required form. The thesis is divided into three main parts. The first one focuses on the description of basic models that will be modified in the last part. The following part deals with a brief description of the company already mentioned above that provided data without which this task could not be demonstrated in practice. The final part includes a detailed analysis of the given task, formulation and description of the mathematical model, which was created on the basis of specific requirements of the company. There is also a comparison of actual results from practice with optimal results
