ESReDA is a European Association which provides a forum for the exchange of information, data and current research in Safety and Reliability and a focus for specialist expertise.

The Project Group (PG) “Resilience Engineering and Modelling of Networked Infrastructure” was established in 2018 and consists of a forum of leading researchers from academia and industry to work on projects relevant to Resilience Engineering for Networked Systems.

This PG focusses on the transport and utilities networks. The disruption of such systems can have a big impact on the communities that they serve. The nature of the threats to these systems is also changing and includes failures, especially of aging infrastructure, natural disasters, the effects of climate change and deliberate acts such as terrorism. 

The following aspects of resilience are considered by the PG:

• Modern engineering systems are growing in size and complexity, they are also becoming more distributed, integrated and autonomous. A unified, consistent approach is desirable to define the concept of resilience, considering the full range of potential threats.

• The metrics predicted along with the methods to do so are inconsistent in the absence of a well-defined proven concept of resilience. A unified modelling framework for resilience is considered.

• Characteristics of networks influence the methods which exist to model network resilience and identify the weaknesses, where the most effort should be expended to protect the performance of the network.

• A whole life, whole system approach is desirable.
