Abstract

Topological analysis based on graph theory, has the merit of revealing the relevant properties of the structure of a network system. In this working paper, the topological analysis is used to analyse the structural properties of the project risk network. The main idea here is that the risks faced by a large infrastructure project are not independent but are often interrelated and can evolve by propagation, whence their structuration in network. Therefore, the appeal to the network theory is not trivial but is a significant development in the field of research on the analysis and management of project risks. The aim of this study is to identify critical risks and interactions among risks with regard to their roles in the network. This will provide valuable information that complements the traditional analysis based on the evaluation of the likelihood and impact of risks. The originality of this work manifests itself, particularly, through the application of topological analysis in the field of project risks management, and the adaptation of indicators of network theory, in particular, the indicators of connectivity, interface and betweenness centrality. The application on a real complex engineering project allows us to validate the usefulness and feasibility of the proposed approach.
