Analysis and risk assessment of risk technical systems to develop of methodology for teaching students using the method fault tree

The aim of the present work is to develop a methodology for conducting exercises for analysis, assessment and management of risk, using a web based tool by identifying and analyzing the risk of occurrence of a dangerous event through the fault tree method. As a result, a framework is presented according to the proposed methodology applicable to the students' training in risk analysis, evaluation and management, and according to accepted assumptions. Approaches for qualitative and quantitative risk assessment are presented at the assumed value of the damages. In addition, a methodology for risk analysis, assessment and management applicable to student training on risk analysis and management has been developed and proposed.

The aim of this paper is to develop a methodology for risk analysis, assessment and management using the event tree method. A sample sequence of risk analysis actions is shown with the use the event tree method in determining the probability of realizing a dangerous event including an exemplary event tree pattern according the example under consideration and with the possibility of calculations and for determining the risk at the accepted value of the damage. A methodology for risk analysis is proposed based on the event tree applicable to student training on risk analysis and management.

The aim of the paper is to develop a methodology for risk analysis and risk assessment of a risk technical system (traffic light scheme) using the fault tree method. Results: Analysis of the risk of risk technical systems through a fault tree gives an unambiguous relationship between element parameters and parameters of equivalent elements describing a system or a part of a system. An example of risk analysis of a risk technical system (traffic light-scheme) is shown with the fault tree method applicable to students training on risk analysis and management, including a sample scheme and a tree scheme (according to accepted assumptions) and with the possibility of calculating it and determining the risk at the assumed value of the damage. Contributions: A methodology for analysis and risk assessment of risk technical systems (traffic lightscheme) has been developed and an example has been developed for the students' training in risk analysis and management.

Quantitative Approaches

The European Railway Agency (ERA) has the challenging task of establishing common safety targets and common safety methods throughout Europe. In this context, the harmonization of risk analysis methods is also discussed. The purpose of this paper is to present a new semi-quantitative approach for the risk analysis of technical systems and the means by which compliance with legal and regulatory requirements can be demonstrated. As a particular reference, a new German pre-standard, which lays out requirements for semi-quantitative approaches, is taken into account.

The purpose of this article is to develop a methodology for risk analysis by transforming structures. A methodology for risk analysis is proposed by transforming structures based on existing links between the system description through a block diagram, a fault tree, and an event tree. Risk analysis of risk techniques by fault tree and event tree provides an unambiguous relationship between element parameters and parity of equivalent elements describing a system or a subsystem. An example of risk analysis by transforming structures is presented, according to the proposed methodology applicable to risk identification, including transformations between block diagram and fault tree and event tree, as well as variants to determine their risk (at accepted value of damages), according to acceptances made. A methodology has been developed and examples of risk analysis by transformation of structures are shown.
