Stroke mechanism of bridge crane
Drábík, Michal ; Sedláček, Martin (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis is focused on the design stroke mechanism of bridge crane with load capacity of 10 000kg. The thesis contains a critical research of today-manufactured crane trolleys and a selection of a suitable conception. Part of the design are calculations of the lifting mechanism base parts, for example: rope diameter, pulleys diameters, complete dimensions of the rope drum, selection and the design of the electric motor, gearbox, brake, frequency inverter, gear and drum coupling. Last chapter is focused on the strength calculation of the rope drum, durability of the bearing, weld strength examination and radial load. Part of the thesis is the lifting mechanism assembly drawing documentations and the rope drum welding assembly.

Design of material flow using discrete event simulation
Seidl, Tomáš ; Sedláček, Martin (referee) ; Škopán, Miroslav (advisor)
The content of this diploma thesis is to create a simulation model of the logistics chain of the production area of an industrial plant in order to design the logic control of material flow. Plant Simulation software from the company Siemens PLM Software is used to create the simulation model. The diploma thesis consists of system analysis of the researched area of the production plant. With the help of the simulation model, simulation experiments and evaluation of the obtained results are made. According to the results, the conclusions are drawn.

Planning of logistics processes by computer simulation
Sedláček, Martin ; Štoček, Jiří (referee) ; Škopán, Miroslav (advisor)
Contents of this diploma thesis is creating of the simulation model of the logistic chain of the internal transport to evaluation of the impacts of the projected changes of the parameters of the logistic chain. The simulation model is created in Plant Simulation software by association Siemens PLM Software. An analysis of the discussed area is also included in the thesis. With the help of the simulation model it is tested if the modification of the logistic chain elements has positive impact on important characteristics of production of the given area. Conclusion are made from the results of the experiments and a modification of the logistic chain is suggested.

Risk management of operation in transportation and haulage company
Sedláček, Martin ; Kalenda, Lukáš (referee) ; Adamec, Vladimír (advisor)
An issue of operational risk management is in modern times an important topic to resolve. Modern fast time, which brings a number of changes may affect the occurrence of risks that may have impact on operating activities of a company. This fact, however, does not depend on the company characteristics like: size, business sector and other factors. Risks are ubiquitous in a business because a business is a very risky activity. Every company should therefore have a risk management system or a procedure to deal with them. This thesis focuses on an analysis of issues of an operational risk management, the current situation in the transport sector and the risks arising from specifics of the transportation sector. Further analysis of risk in specific transport-forwarding company is based on previously conducted analysis. The output of this work is to propose countermeasures to prevent the effects of identified risks or to propose a general procedure for the operational risk management of companies operating in the transport sector.

The engine of a tractor
Mátyás, Attila ; Sedláček, Martin (referee) ; Kašpárek, Jaroslav (advisor)
This thesis deals with the design and selection of a small utility tractor engine unit. The first theoretical part briefly describes tractors with similar weight category, provides an overview of existing tractor brands and their comparison. The second part of this thesis consists of analytical calculations based on the provided parameters of the tractor. Total power will be the sum of the individual power required for the various technical operations during functioning. The last part deals with selecting the suitable engine unit from the available brochures of world manufacturers based on the calculated values.

Stroke mechanism of bridge crane
Tomeš, Jakub ; Sedláček, Martin (referee) ; Škopán, Miroslav (advisor)
The bachelor thesis deals with the design of bridge crane lifting gear for a load not exceeding 10,000 kg. The work includes the design of the basic parts of the lifting gear, such as rope diameter, rope drum and rollers. There is also included the choice of standardized parts such as electric motor, crane gearbox, flexible clutch or drum brake. The last chapter describe the strength calculation of the rope drum and the bearing life calculation together with the design of welds and tight pen. The output of the bachelor thesis is the drawings of the cable drum weld and the mechanism of the lifting mechanism.

Modification of material flow in production area
Řehák, Karel ; Hloska, Jiří (referee) ; Sedláček, Martin (advisor)
The content of this bachelor thesis is to create a simulation model of the production process and logistics chain in order to evaluate the impacts of proposed changes in the production process parameters. The simulation model is created by Plant Simulation software from Siemens PLM Software. An analysis of the discussed area i salso included in the thesis. With the help of the simulation model it is tested if the modification of the production pro-cess elements has a positive effect on the production characteristics of the given area.
