Fousek, Jakub ; Kuncová, Martina (advisor) ; Fábry, Jan (referee)
The diploma thesis deals with simulation of manufacturing of the order for production of 50 pieces of radial fans RFC 200 in company ALTEKO, Inc. The aim of this diploma thesis is to find out whether it is under current conditions feasible to complete the order and deliver goods to customer in time. The order also includes selection of appropriate engine supplier using the methods of multicriteria evaluation of alternatives. The objective of the first three chapters is to familiarize reader with theoretical basis of multiple criteria decision making, simulation models and project management. The fourth part describes the concept of simulation program Simul8. The fifth part provides information about the company ALTEKO, its history and current business running. In the last chapter theoretical knowledge is used to real problem by using the most important tool simulation of manufacturing process. In the simulation current state of the manufacturing process is explored and proposals how to eliminate weak bottle necks of the process using the experimenting with the model. Based on the obtained results the possible solutions which should be helpful for improvement of company´s processes even in case that the order is completed in time will be proposed.

Simulation of the client workplace of the health insurance company
Karbusická, Martina ; Dlouhý, Martin (advisor) ; Fábry, Jan (referee)
Simulation is an advanced tool to capture and simplify a complex system and it allows to track the effects of changes in it to function of the entire system. The aim of the thesis was to model the current function of the system and monitor the effects of changes by experiments with the model in order to find a new and better solution. In this thesis, the running of the client workplace of Všeobecná zdravotní pojišťovna ČR was monitored and the simulation was based on real data from May 2012. The simulation was performed using the software Simul8. The results of the base case show that the system leads to accumulation of entities and long time spent in the queue. Within experimenting with the model there were created 8 scenarios that modify some parts of the system. Firstly the results of the scenarios were compared to the base case and then they were compared with each other. The scenario that was chosen as the best, was better in most of parameters compared to the base case. The parameter with the worst value in the base case - time spent queuing for a normal counter - has improved by 62 % in the new scenario. This scenario was chosen as a new and better solution for the current system.

Distribution strategy after opening the northern highway in the Czech Republic
Jindrová, Věra ; Fábry, Jan (advisor) ; Kuncová, Martina (referee)
The aim of this work is to simulate and to try to predict a distribution strategy by opening the northern highway in the Czech Republic based on the current traffic flows and existing trends. The speedway R35 will be after the completion of all platforms the northern backbone route connecting Bohemia and Moravia. With an overall length of 260 km it will be the longest Czech speedway. Another attraction of this highway is the connection of four regional cities and six strokes crossing the motorway network. The prediction of traffic volume will have a task to reveal the simulation model of overt and covert traffic flows, including the approximate volumes of traffic. The author assumes that the completion of the R35 between Mohelnice and eastern Bohemia will have a strategic importance not only for relieving highway D1, but also due to the conversion of the distribution strategy in the whole country, including new opportunities for the construction of distribution centers strategically located.

Simulation of the operation of the hospital department
Olejár, Filip ; Dlouhý, Martin (advisor) ; Kuncová, Martina (referee)
This diploma thesis deals with the solution to a real situation that occurred at Nemocnice Na Františku in Prague. The problem is solved by using a computer simulation in SIMUL8 simulation program. At the beginning I describe the theoretical foundations that are afterwards used as a basis for the main practical part. The main subject of the work is a simulation of an operation of the hospital outpatient department. The hospital management decided to change the system for handling patients operations. I have created simulation models for particular workday and weekend means of patients serving operations. The created simulation models and their outputs are evaluated in the final part of the thesis and will serve as a basis for making reorganization decisions in the hospital. The provided advice for hospital management fulfills the goal of this thesis.

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.
