Wood log splitter
Růžička, Václav ; Mergl, Václav (referee) ; Škopán, Miroslav (advisor)
The aim of this bachelor’s thesis is to make a brief research about wood splitters and compare their design, parameters and individual drives of these machines. In the next part of the bachelor’s thesis is devoted to the design of the machine's own concept. At first, the hydraulic circuit is designed and the hydraulic components are calculated for it, and then the splitter frame is designed. The work also includes drawing documentation of the entire assembly and frame welds.

Posouzení vlivu paliva na parametry zážehového motoru
Růžička, Václav
Diploma thesis describes current fuels for gasoline engines in theoretical part. It de-scribes conventional fuels: gasoline, gaseous biofuels and liquid biofuels. This section talks about: familiarization with manufacturing, raw materials for production with their pros and cons. Fuels are comparing with one another in the tables. In a separate chapter is more about biofuel ethanol, which were measured in the practical part. The practical part describes the motor testing, dynamometer and engine on which measurements were made. On the engine we compared the effects of fuel (N95, E70 and E32) to power and torque, fuel consumption, exhaust gas temperature, engine effi-ciency and the energy supplied in the fuel. The results of monitored parameters are listed in tables and compared in graphs. The results show that ethanol has a positive effect on performance and engine torque. The negative impact of ethanol in the fuel is increased fuel consumption.

Optimization of inventory of finished products in LASSELSBERGER Ltd.
Blažíček, Martin ; Svobodová, Hana (advisor) ; Růžička, Václav (referee)
The thesis deals with minimizing of the inventory of finished products in the ceramic industry. To reduce inventory the ABC and XYZ analysis was used for the sorting of products into the groups and particular ways were suggested to reduce inventories of finished products. In the theoretical part are described the theoretical assumptions for inventory management issues such as costs, demand, or different methods of inventory management. Then the technological process of production of ceramic tiles follows. In the practical part, entire knowledge of the theory is applied to the problems of ceramic tiles production in LASSELSBERGER, Ltd. It concerns specifically about 1284 products analyzed by using ABC and XYZ methods. Proposed methods and their effect on saving of storage space (storage space saving) were compared afterwards. The result of the work is a comprehensive product portfolio analysis of LASSELSBERGER, Ltd. indicating to company management, which economy measures will ensure the highest costs saving.

Measurement of effective deployment format for lines in RAKO III
Blažíček, Martin ; Svobodová, Hana (advisor) ; Růžička, Václav (referee)
The bachelor thesis deals with the optimal production batches in the ceramic industry and to some extent the stock solution. In the theoretical part I try to summarize the issues concerning the optimal production batches, then the issue of stock, then the costs and theories of two models for calculating the optimal production batch. The next section deals with the characteristics of the firm. Explaining further production of ceramic tiles. The practical part then all the theoretical knowledge is applied to the particular case of the production of ceramic tiles. For the factory at Lubné Rakovník I was able to determine the optimal production batch sizes for each tile, the sensitivity of the cost of scaling benefits versus optimal production rate and ultimately the optimal length of production cycle.
