Degradation Analysis and Preventive Maintenance Modelling and Assessment for Improved Resilience of Critical Infrastructures - Application to Torrent Checkdams

Résumé

Natural threats have become more familiar, to the extent that requires ensuring the resilience of critical infrastructures. Critical infrastructures have always been complicated to study and assess, as they are all characterized by a collection of components that have numerous dependencies and interactions. Recently, several methods and frameworks have been put forward to assess and analyse comprehensively system's resilience. However, these methods have insufficiencies in identifying some hidden risks arising in a complex infrastructure. Therefore, it is essential to go beyond conventional methods and to develop risk strategies and decision-making techniques in order to overcome classical static assessment methods. This paper contributes to analyse the context of critical infrastructures with the ultimate objective of proposing new methods of choosing preventive maintenance strategies. It represents a modelling approach based on Petri nets to study the dynamic behaviour of the system when exposed to deterioration mechanisms and to support maintenance decision-making. The application is carried out on torrential checkdams in which the model results are presented and discussed in the paper.
