This bachelor thesis discusses Queuing models one of many disciplines of operational research. At the beginning of theoretical part is introduced operational research and briefly described different disciplines. Then there are described queuing models and laid the theoretical basis, in which are explained main characteristics of queuing models. At the end of theoretical part is mentioned how to classify queuing models. In the practical parts is selected problem which will be solved using queuing models. This problem is servicing customers at the branch of company Česká pošta. From the obtained information is created queuing model, which is classify as M/M/c according Kendalls classification. On the created systems are applied analytical calculation and used simulation model. For simulation is used program MS Excel and randomly generated numbers. Process of creating simulation model is continuously recorded. Simulation model is running for 5000 customers to ensure that the results have adequate explanatory power. The created simulation model is found to be invaluable at the final comparison of results obtained from both approaches. Simulation model provides more information, that in analytical model are not available. These additional valuables information are use for the closing recommendation.
