Infrastructure assets § Not the same as other types of capital stock (Égert et al,
2009) § natural monopoly characterised by public good
§ citizens gain universal access to basic requirements § address poor service and ecological concerns via public forums and
political means § enabler of economic activity as well as social cohesion § network effects and spill-overs into other sectors
§ property prices hikes when OFSTED changes a school evaluation. § large scale with long life-cycles of investment and alternative
financing models § extensive government intervention
§ various forms of regulation or state ownership which can have competition enhancing effects
§ economies of scale

Infrastructure systems § Built traditionally for the long-run (Victorians) § Embedded often explicit assumption of the investments
worthwhile nature based on some cost-benefit that will arise contingent upon the use made of the infrastructure
§ Implies that the system will need to be uninterrupted and undisturbed otherwise benefits delivery would be compromised.
§ Result is that infrastructure systems have been kept separate and isolated as far as possible using controls to ensure benefits delivery. § E.g. legislation, regulation, functional departments and organizations
(e.g. electricity, water), disciplinary (academic) specialization and industrial (and professional) groups
§ Controls act as negative feedback to ensure a status quo in the infrastructure system creating inertia and leads to sweating of assets and avoidance of adaptation

Focus on interdependencies § Interdependencies create vulnerabilities to
cascade failures and their associated problems [BIS] but they also open up new entrepreneurial opportunities to create and capture value in international markets [Frontier Economics]

ICIF vision
§ To achieve a major improvement in commercialisation and policy-making through a step-change improvement in § the integration of knowledge from the social and
engineering sciences on the relationships between the emerging technical and market opportunities brought about by interdependencies and their commercial exploitation by investors and firms.

Reasons to understand interdependencies • Climate change • Increase in extreme events (storms, flooding etc) • Risk of terrorism • Increasing dependence on ICT • Increasing dependence on electricity supply • Poorly understood risks of cascade failures • The need to upgrade/replace aging infrastructure • Concerns regarding energy security
Infrastructure comprises a complex system of systems in which wicked problems and baffling interacRons are pervasive. Infrastructure interdependence has many dimensions, holisRc understanding of these dimensions is required to help protect essenRal services or criRcal naRonal infrastructure.

WSB: Risk Identification and Analysis
SpaRo-‐temporal analysis idenRfying: • Risks and vulnerabiliRes including
cumulaRve risks • OpportuniRes for improving
resilience and adaptaRon • Challenges and constraints
A range of non-‐infrastructure interdependencies and challenges/opportuniRes will be considered (e.g. policy, environment) Differing forms of failure and threats to infrastructure, parRcularly those with differing Rmescales (e.g. extreme events and long term climate change) will be explored
Constraint (e.g. protected
habitat)
Low risk /opportunity area
Vulnerability (e.g. flood risk)
10
Individual site
• Individual site with a small number of interdependencies (e.g. energy, water, ICT) • Interviews with industry partners • Data collec?on • Cri?cal components analysis
Mul?ple sites
• Mul?ple sites and interdependencies • Spa?al-‐temporal models • Failure analysis (e.g. the sources and influences of failures) • Simula?on and agent-‐based modelling of failure types
Regional
• Increasing complexity • ‘System of systems’ vulnerability analysis • Considera?on of scenarios – e.g. socio-‐economic, policy and environment change • Iden?fica?on of risks and opportuni?es (e.g. adapta?on), par?cularly their distribu?on and trade-‐offs
InternaRonal
• Interna?onal and transboundary challenges (e.g. ports, marine renewables) • Learning from interna?onal experiences
The research will consider the differing scales at which interdependencies occur and affect organisaRons

WSC & WSD: Delivering innovative business models § Be\er understand the interface between infrastructure assets,
their end-‐users on the one hand, and commercial enterprises, on the other.
§ Explore how services are delivered through infrastructure and how value is created, distributed and captured by commercial enRRes that parRcipate in the delivery of services.

“A business model is a well-specified system of inter-dependent structures, activities and processes that serves as a firm’s organizing logic for value creation (for its customers) and value appropriation (for itself and its partners).” Sorescu, A., Frambach, R., Singh, J., Rangaswamy, A., & Bridges, C., InnovaRon in Retail Business Models, Journal of Retailing, 87S (1,2011), S3-‐S16.
§ InvesRgate governance structures, organizaRonal forms, and business models that best describe how infrastructure operates interna?onally.
§ InvesRgate possibiliRes to improve service quality and economic efficiency of infrastructure, focusing on the transport and water sectors.
§ Research will be based on a number of nested case studies, spanning different analyRcal levels, from city governance, to organizaRonal forms and business models. Furthermore, two streams of industry engagement workshops are planned. One with a longitudinal focus group and one ad-‐hoc and case study based.

§ Understanding the infrastructure delivery challenge, together with the development of innovaRve infrastructure modelling and novel business models, involves a paradigm shi[ in the way in which infrastructure is conceptualised.
§ Making this transiRon draws on the ability to learn as part of a conRnuous and iteraRve journey.
WSE: Learning Journey

§ The ICIF Learning Journey Framework Supports and scaffolds the ways in which infrastructure stakeholders learn and lead, in order to make learning visible, so as to enhance the speed with which they develop and implement innovaRve and effecRve soluRons to the complex ‘wicked’ problems of the 21st Century Infrastructure System.

Urban Systems & their futures § Urban areas cover just 2.8% of the Earth’s
land area, but over 50% of the human population lives in them § these proportions are increasing rapidly § in the developed world the proportion of urban
dwellers is even greater. § Urban areas also use most of the resource
produced elsewhere, and generate much of the waste.

Known Infrastructure Time Lines - 2050
© Cranfield University 2014 20 Engineering the Future, May 2013
Future policies and plans § Across sectors, timelines show significant planning in some areas
of national infrastructure and a paucity of planning in others. § They also show that planning in some infrastructure areas, such
as ICT, has naturally much shorter time horizons as technological development and replacement is much more rapid than in other areas, such as transport.
§ It is important to note that the issues driving the policies and plans vary across sectors, ranging from high level policy commitments such as carbon emission reduction, to commercial developments such as 4G mobile communications.
§ As well as providing this visual mapping capability, the timelines should be used to identify where positive and negative interdependencies exist both within infrastructure sectors and across multiple sectors

Operational Resilience - Network topologies

Yemini, Columbia University
Robustness between interdependent networks § How can robustness be improved through network connectivity
understanding? § Using different types of network topology (distribution of degree-
nodes) and numbers of nodes § Assuming each node in network A depends on one node in network
B, and vice versa § Attending to additional characteristics
§ the load on the node, § the dynamic changes of the load, § and the capacity of the node to handle the extra load in the actual
interdependent infrastructure networks. § Testing different link types:
§ assortative link (AL): high-degree (low-degree) nodes in A network link high-degree (low-degree) nodes in B network
§ disassortative link (DL): high-degree nodes in A network link low-degree nodes in B network
§ random link (RA), connect randomly two nodes in networks A and B
