Fuzzy logic methods for the risk assessment
Kovář, Kamil ; Vymazal, Tomáš (referee) ; Misák, Petr (advisor)
Master´s thesis deals about problematic of fuzzy logic, fuzzy sets and operation with them. Also thesis describing procedure of quantification risks through fuzzy sets, process of fuzzyfication, defuzzyfication a theirs application in the expert systems FMEA and FMECA. Using selected chapters of czech states standards are established critical areas in building process, it is a chapters about quality, safety and environment. With these areas by using fuzzy sets theory are created the procentual input values in the decision program, created by Matlab. Output from program is decision how big the risk rate is and if is necessarily make corrective measures. A concrete example is the production of concrete goods, describing production process and composition of fresh concrete. A practical example, created by using information from real company, is a decision about the risk rate in the qualitative area.

Model of small air press
Uherek, Vítězslav ; Macho, Tomáš (referee) ; Štohl, Radek (advisor)
This thesis deals with design construction of laboratory model of air press and also proposes of safety measures for this machine. Before the design itself, norms concerning machinery construction were surveyed. There are two norms mentioned in the text ČSN EN 61 508 and ČSN EN ISO 13489-1. Next part shows practical demonstration of machine safety analysis using SISTEMA software tool. Changes to the safety measures were made according to the result of this analysis. Important part of this thesis is also design of control software for the air press in RSlogix5000 environment using Ladder logic and also created visualization of pressing process and show up on to visualization panel PanelView 700.

Framework for on-line service security risk management
Mészáros, Jan ; Buchalcevová, Alena (advisor) ; Čermák, Igor (referee) ; Doucek, Petr (referee) ; Jirovský, Václav (referee)
This dissertation thesis is dedicated to on-line services security management from service provider's and service consumer's viewpoints. The main goal is to propose a framework for on-line services security risk management, to develop a supporting software tool prototype and to validate them through a case study performed in a real-world environment. The key components of the proposed framework are a threat model and a risk model. These models are designed to fit specific features of on-line services and the surrounding environment. A risk management process is an integral part of the framework. The process is suitable for frequent and recurrent risk assessments. The process comprises of eight steps, related roles and responsibilities are defined for each step. The process execution results in identification and execution of proper tasks which contribute to treatment of identified security risks and deficiencies. Documentation and reporting of an overall level of on-line services security over time is possible if the process is executed on a regular basis. The proposed framework was validated through a case study performed in a large enterprise environment.
