Abstract: The interdependencies within and between infrastructure systems can produce benefits and risks. The perception and value of these relationships can vary significantly depending on the viewpoint of the actors within the system. The current methods for describing these relationships do not necessarily account for these different perspectives, and tend to focus on reducing the risks and vulnerabilities associated with interdependency. By taking a holistic, multi-stakeholder approach of the infrastructure system it is possible to also identify the proactive opportunities for improving efficiency, effectiveness and resilience that can emerge from the relationships. A taxonomy is presented which allows for the characterisation of infrastructure relationships in multiple dimensions, with particular focus on identifying opportunities in a way that is therefore complementary to current methods. An application of this taxonomy to the identification of potentially beneficial relationships within the UK infrastructure system is described.
