Assessment of Quality-related Risks by the Use of Complex Networks

Abstract

This study introduces the NTS network as a new way of analysing, verifying and improving quality-related risk assessment. NTS is based on a network science approach that models complex systems by graphs. By using N, T and S-Graphs as the elements of NTS, risk events that play special role in the risk management system can be identified. Based on their characteristics, the strength of their potential causal connections can be recalculated, providing more precise predictions of the occurrence frequencies of events.
