SBRA method and the development of its application
Půstka, D. ; Marek, Pavel
Tento příspěvek obrací pozornost na potenci l metody SBRA, zvláště u ocelových konstrucí. Plně pravděpodobnostní řešení daného problému je tu ukázáno na dvou příkladech. Na ocelovém nosníku ovlivněném korozí a na akumulaci poškození únavou na ocelových podpěrách namáhaných větrem. 295 This paper turns attention to the potential of the simulation based reliability assessment method SBRA, considering especially the durability assessment of steel structures. A fully probabilistic approach is demonstrated using two examples. A steel component is exposed to time dependent effects of corrosion and assessment of the accumulation fatigue damage.

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.
