The Safety Analysis for the Safety-Critical Processes

Abstract

Ensuring a safety of technology process is very important. Therefore it is necessary to include the safety analysis into the developing process of automatic control system and also to curricula at technology universities and high schools. The aim of the article is to propose a methodology for implementing a model-driven safety analysis of dynamical technology systems. The safety analysis is performed in the process of control system development, especially aiming at safety-critical processes of system operation. The methodology was divided into a few steps. The individual steps of the methodology are carried out in a hierarchical sequence. The roles of individual methodology steps are detailed in the paper. The principle of safety-critical process monitoring based on models is also described in the presented article.
