Safety of technological systems
Jiříček, Petr ; Pavlík, Josef (referee) ; Hammer, Miloš (advisor)
The work deals with the safety of technological systems and can be divided into two main thematic units. The attention in the first theoretic unit is paid to aspects that affect the safety of technological systems during their technical life. It describes, together with elementary norms and acts solving the products safety, the most important principles for creating and analysing the safety. It clarifies the origin of company’s risk management, part of its quality management, mentions the faults in which products can be found and also describes the failures which have the biggest effect on these faults and of course on the safety too. Attention is further paid to the reliability analysis, as the tool that helps to create the products safety in the pre-manufacturing phase and also to technical diagnostic, as the tool to keep the safety in after-manufacturing phase. The second practical unit arithmetically analyses the safety of two high-voltage transformers. For that it was used the database of real operation numerical values that were gained during diagnostic investigations on these transformers. In addition it describes mentioned diagnostics methods and gives the new procedure for analyse of transformers’ safety by criteria matrix and weighted sum approach. The main contribution of the work can be considered the checkout and the evaluation of this procedure for use in elaboration of high-voltage transformers diagnostic values for analyzing their safety.

Cloud Computing and its influence on the Business Agility
Podlipský, Šimon ; Lorenc, Miroslav (advisor) ; Koliš, Karel (referee)
The thesis focuses on the implementation of Cloud Computing automatization into the firm, on its development and influence on the Business Agility. The thesis shows the application process on LidskáSíla s.r.o., the company with a goal of dominating the market of services in the Czech Republic and possibly abroad as well. The company tries to achieve this aim using Cloud Computing and also using methods of Operations Research, primarily used for processes optimization and decision making. The thesis firstly explains necessary terms concerning Cloud Computing and Operations Research and describes used principles. After that presents the company and its activity, following with examining the implementation of automatization using Cloud Computing and methods of Operational Research. Finally, it comes to a conclusion that using Cloud Computing for process automatization have positive influence on the Business Agility under certain circumstances.

The Evaluation in Figure Skating from the View of the Decision Making Theory
Erbsová, Markéta ; Dlouhý, Martin (advisor) ; Nečas, Dalibor (referee)
The evaluation methods of competitors in figure skating are the key problem of this sport. The 6.0 system of evaluation was in use until the year 2004. In such system referee compares competitors one by one and decides on the rank. The 6.0 system can be described by method of Expert Judgment and/or Group Participation. In year 2004 International Skating Union introduced the new system. In this new system is in the role of the decision maker mainly the competitor not the referee. The competitor chooses elements of his program which maximized the total point benefit. We can find out the point value of every element in SOV -- Scale of Values. Nowadays the skater can decide according to the Decision Making under Multiple Criteria theory, we use Weighted Sum Approach method which is sufficient for our purpose. In this thesis both systems are going to be explained on particular cases and linked with methods of decision making theory.
