This thesis deals with optimization problems of the parcels distribution. This issue can be solved on the ground of traveling salesman problem whose mathematical and economic model, including their modifications, are presented in the theoretical part of the thesis. We can solve these problems by using exact methods, heuristic and metaheuristic algorithms. In the theoretical part are described traveling salesman problem, traveling salesman problem with time windows, traveling salesman problem with multiple time windows and dynamic traveling salesman problem including possible ways of solution. In the practical part we can find application of problems on the real example, when we are finding the shortest possible route for the PPL's employee under different assumptions. The solution is obtained by using solver Gurobi within the modelling system MPL for Windows. In conclusion of the thesis the results are summarized and models are compared with each other.

The aim of this master thesis is to analyse the market of courier, express and parcels services. It focuses on the issue of relevant national and international legal framework, with a particular interest in the principles of liability. Furthermore, it provides information on activities of the major courier, express and parcels suppliers: TNT Express Worldwide and DHL Express. These two companies and their Terms and conditions of carriage are subjects for a case study which deals with logistics provider's liability for destruction or loss of or damage to cargo and liability for damage caused by delay.
