Abstract

The aim of the article is to present the possibilities offered by network models. This article discusses the network model of risk analysis in technical structures. We are discussed some network centrality measures and their use in risk analysis. We have proposed a mixed, expert-formal model for analyzing the risk of asset risk in technical structures based on own methodology of network building. We shown that mathematically model of structure of the network and its corresponding physical are linked by bijection. This creates a unequivocal model for quantitative risk analysis.

Highlights

Known and common development and describing the concept of the risk assessment process is PN-EN 31010: 2010
We have proposed a mixed, expert-formal model for analyzing the risk of asset risk in technical structures
The expert component of the model, is always present at the stage of creating a triad of "asset - vulnerability threat". It results from the methodology of building a network model of the examined technical infrastructure [7] and principles of risk analysis

Summary

Introduction

Known and common development and describing the concept of the risk assessment process is PN-EN 31010: 2010 Standard is not intended for certification, regulatory or contractual use but provides guidance on the selection and application of systematic and methodological risk assessment techniques [1]. Risk assessment carried out in accordance with this standard supports other measures of risk management. It shows the use of certain techniques, referring to other international standards, which describe in more detail the concept and application of these techniques. As examples of such techniques the norm indicates, for example: "brainstorming", Delphi technique, preliminary analysis of threats, Failure Mode and Effects Analysis, FMEA, Fault Tree Analysis, FTA, methods based on Bayesian statistics and Bayesian networks. The techniques are classified according to their use at different stages:
