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 six basic steps. The individual steps of the methodology are carried out in a hierarchical sequence. Further, roles of individual methodology steps are detailed. In the next part of the article, the principle of safety-critical process monitoring based on models is described.

The content of this article is the proposal of process of the safety analysis for complex dynamic systems. The safety analysis is carried out in process of the proposal of control system for safety-critical processes. In preliminary hazard analysis is done the identifying all possible risks by PHI method. The PHA method is used to analyze these risks. The method of safety analysis depends on various safety-critical states of system which are system are controlled by models. We propose to use the method SQMD for modeling these states. This method combines qualitative and quantitative methods of modeling states and takes advantage of both methods. The model of the proposal is shown in the diagram. The article includes detailed description of the tasks for each step of analysis.

The method of safety analysis depends on various safety-critical states of system which are system are controlled by models. We propose to use the method SQMD for modeling these states.

The objective of the article is to demonstrate the principle of the SQMD method concept for performing safety analysis on the example of a dynamical system. The safety analysis is performed in the process of designing a control system for safety-critical system processes. The safety analysis is aimed at using the models to monitor different critical points of the system. For the purpose of modelling, we suggest using the SQMD method combining qualitative and quantitative procedures of modelling and taking both methods advantages.
