Application of operational research methods in selected company
Bílková, Jitka ; Kvasnička, Roman (advisor) ; Horáková, Tereza (referee)
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.

Use of simulation programs for analyzing and improving the operation of the company (real situation)
Záhorovská, Zuzana ; Kuncová, Martina (advisor) ; Fábry, Jan (referee)
Aim of this thesis is to analyze the current situation, to identify bottlenecks and to propose improvements to the department of acquisitions in the selected financial company, which is an important part of the Czech market and which desire not to be named. In the first part of my thesis is provided to the reader a theoretical basis necessary to understand the following text. Then I create simulation models for individual teams, which take part in the mentioned department. These models are based only on average and total values. That is why in the next section, there is described the work to bring them closer to reality with shifts of administrators and the variable number of entities, which are processed throughout the day. Based on the analysis of calculated values, I propose two methods of redistribution of actions to reduce the number of employees and to increase their efficiency.
