The Management Of Stocks Of Spare Parts Logistics Chains
Vávriková, Lucia ; Kuncová, Martina (advisor) ; Zouhar, Jan (referee)
Thesis on the theme "The Management Of Stock Of Spare Parts Logistics Chains" deals with the specification of logistic chains, spare parts inventory management and functioning of these chains. The theoretical part focuses on the definition of the theoretical background needed to understand the functioning of these chains. It ranges from the definition of the logistics chain, through ABC analysis to the detailed characteristics of the chain of spare parts. Besides a general overview the thesis includes example from real practice. In the practical section, through simulation models thesis presents the operation and management of the spare parts logistics chains. The practical section shows the simulation model of the current situation and compares it with the model after the introduction of stock management in the company.

New product installation simulation
Medonos, Michal ; Dlouhý, Martin (advisor) ; Kuncová, Martina (referee)
One of the products produced by Motorpal a.s. is a camshaft. Recently, the company signed a contract with Bosch company to produce new types of camshaft. The analysis of the impact of the contract on the production was made by simulation. To perform the simulation it was necessary to map the whole process. The simulation of the current state was made in the first phase. The results shew many uneffectivnesses in the process and lack of capacity of some workplaces. Some changes in the process were suggested and tested with the aid of the simulation. The best results were achieved when the single-item flow was used. In the second phase the production of a new type of camshaft was added to the simulation. Analysis of these results was divided into two parts. The new production was analysed in the first part and it was discovered that the planned capacites are very deficient. The impact of the new production on the current one was analysed in the second part. It shew that this impact is negativ, especially on the duration of production.

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.

Optimalizace najetí kontinuální chemické výroby
Svátek, Michal ; Kuncová, Martina (advisor) ; Heřman, Jan (referee)
Práce se zabývá optimalizací najíždění kontinuální chemické výroby, jenž má značný vliv na ekonomiku procesu. Základním pilířem práce je myšlenka optimalizace této komplexní operace na základě historických dat bez nutnosti užití složitých chemicko inženýrských výpočtů. V práci je využito moderních metod řízení ke zmapování procesu a následně k vyhledání míst, ve kterých dochází k největším prodlevám. Druhá část práce se zabývá optimalizací procesu s využitím modelů a metod řízení projektů, zejména síťové analýzy. V závěru práce je proces simulován pomocí metody Monte Carlo.

The Optimization Methods with Utilization of the Simulation in MS Exel
Škulavíková, Štěpánka ; Kuncová, Martina (advisor) ; Fábry, Jan (referee)
Thesis is based on original self-made application programmed at VBA in MS Excel 2007. The reason to build this application was integration of simulation Monte Carlo and chosen optimization methods. The application allows do simulation of the knapsack problem and of the assignment problem with uncertainty. The parameters of these models are possible to set up as changing values in dependence of chosen probability distribution. Output of the simulation is a probability recommendation which objects should be used. Choose of objects depend on optimized models. Results of both models are represented by statistical indexes, tables of parameters and graph.

Selected Software Products for Simulation Modeling and its Comparison
Láznička, Jan ; Mildeová, Stanislava (advisor) ; Velehradský, Petr (referee)
A thesis deals with simulation modeling. After opening theoretic information about models, discrete and continuous simulations, computer technologies for systems modeling and individual phases of simulation process, there follows a case study, which demonstrates using of three software products for simulation modeling -- SIMUL8, Simprocess and Powersim Studio. Created models, experiments with them and given results, including well-arranged tabular comparison of mentioned computer programs according to defined criteria, point out strengths and weaknesses of each software. Simultaneously, data for selection of an appropriate program are presented, depending on a sphere type, which is simulation modeling to be applied on.

Project of E-shop system for support of small producers bohemian glass segment distribution.
Kocina, Ondřej ; Mildeová, Stanislava (advisor) ; Jandoš, Jaroslav (referee)
Essay analyses problems of bohemian glass small producers segment and in the scope of the real firm strategy suggests their concrete solution. Analysis finds causes of the segment problems in inappropriate combination of product, market and distribution channels. Author finds possible solution in the oligopoly price leader market model. Results of the problems analysis are together with firm and its environment analysis used for SWOT analysis. Management of the firm chose S-O strategy, which aims sustainable development of the firm, differentiation of the product and enlargement and diversification of the market space. Results of the analysis are used for creation of partial strategies and plans: marketing mix and information strategy. Information strategy includes concept of the new information and communication system suggestion. Suggested system is based on hosted web e-shop application and internet communication software component. System enables to flexible react on the changes of firm strategy and plans, and enables to create individualized and individual services. Chosen architecture is ideal for the rise of virtual teams System should help to emerge integration and synergic effects.

Monte Carlo Simulation and Financial Planning
Vyhlídka, Jan ; Hnilica, Jiří (advisor) ; Sieber, Patrik (referee)
The purpose of this paper is to clarify the Monte Carlo method, related time series forecasting and their application within the Crystal Ball environment. The theoretical part explains the way how to define the assumptions and the fundamental principles behind it. The application part demonstrates the forecasting of revenues and costs of RWE Transgas,a.s. on the basis of the average monthly temperatures, the prices of oil derivatives and the changes in the exchange rates.
