Flexibility is an important value driver for hospital infrastructure in a highly unpredictable health care environment. We illustrate this by way of a case study based on the development of a major UK teaching hospital over the past 80 years. We then lay out some principles for the articulation of the value of flexibility to enable the designer to make an economic case for a flexible infrastructure. Finally, we argue that hospital procurement under Public Private Partnership (PPP), in particular under the UK Private Finance Initiative (PFI), can be an inhibitor to the design and development of flexible infrastructure. To realize the value of flexible infrastructure systems, the PFI parties need to create a genuine long-term partnership. The private parties have to stay engaged during the lifetime of the infrastructure to help adapt it to developing circumstances and thereby minimize value risks, maximize opportunities if and when they arise, and allow the public sector to reap as much social benefit from the infrastructure as possible.

This paper describes an approach to road network monitoring. The approach has the following components: a multi-agent hierarchical monitoring system in which the agents are network elements, such as crossings, road segments and routes, software engineering techniques to handle legacy sensors and to homogenize their heterogeneous data streams, distributed Kalman filtering to reduce sensor noise and a traffic simulation model to help in predicting future traffic states and to replace missing physical sensors. The approach has resulted in a real-life test bed for network performance monitoring in which various configurations of agents and various ways of distributed Kalman filtering can be tested. The current, still rather simple monitoring configuration is already in operational use for traffic management.

Floating cranes could be used to increase the berth capacity for the largest container vessels, making it possible to reduce the vessel berth time. By adding floating cranes on the waterside of a berthed container vessel, the berth productivity could be increased without disturbing the landside operations. Containers would be loaded directly into barges, which could transport the containers to an inland barge terminal. This would not only reduce the pressure on the deep sea terminals and connecting road infrastructure, but could possibly also reduce the total handling costs for containers to and from the hinterland. This paper presents the findings of a study focusing on the feasibility of such a floating crane concept. The paper discusses the conceptual design of the crane itself, as well as its integration in the current logistic processes and its potential market.

This paper seeks to the industrial and technology policy choice in a transitional economy with some insights from constitutional and historical perspectives to develop a model for the policy analysis. By examing the previous empirical research and a China's digital convergence case study, the paper asks to what relevance constitutional choice and governance integration have effects on policy-making. The paper finds theories and case present the constitutional choice is the premise for policy making for industrial policy and technology policy, and the governance structure should be with a view to integration nor diversion, the industrial and technology policy should reflect the public value through a constitutional and institutional process, the choice of industrial policy or technology policy should have a historic view. This article embraces the model of industrial/technology policy, based on multi-perspective view for transitional economy.

This paper presents a method to compare and evaluate alternatives for bulk energy transport to meet evolving needs for electric energy consumption. In particular, it offers insight into the cost and environmental tradeoffs between mine mouth generation with electric transmission technologies and transporting primary energy resources with generation near the customer. A straightforward bulk energy transport model is constructed to address relevant combinations of environmental and other constraints, fuel and capital costs, and advanced technologies. The model uses a life cycle analysis framework and transforms externalities in dollars to compute social as well as private costs. Uncertainties are explored in a sensitivity analysis. The best alternative for bulk energy transport depends on the amount of energy to be transported, the distance, the initial energy source, existing infrastructure, and externalities such as air pollution, safety, noise, and electromagnetic fields.

Although most of the congestion is caused by commuters in the rush hours, the continuing growth in container traffic in the Port of Rotterdam is also contributing to the traffic-jams. Long traffic-jams on the main access road A15 to the port and at the sea terminals result in long transport times and an unreliable delivery of the cargo. A Container Transferium situated in the direct hinterland of the Port of Rotterdam is a new logistical concept which allows for large numbers of containers to be transferred by inland vessels in a single movement from the sea terminals at the Maasvlakte to the Transferium and vice versa. The Transferium can lead to an improved reliability thanks to a better planning of the inland ships or ¿shuttles¿ and a better handling of the trucks, which have no longer to deal with traffic-jams en route to sea terminals. The improved reliability is very important for the Container Transferium, and helps to justify the costs of the extra handling per container. The paper evaluates the potential of this new hinterland transport concept for the Port of Rotterdam.

Complementarity problems are a class of optimization problems which widely pervade infrastructure systems. Complementarity problems capture the concept of network and system equilibrium without the use of a mono-objective function. As a result these problems are useful for modeling infrastructure systems subject to use by actors with varied interests and objectives. Complementarity problems have been applied to both technical as well as economic systems. As such complementarity problems are particularly well-suited for modeling mixed or socio-technical systems. This paper provides a brief tutorial on complementarity problems, reviews the application literature on these problems, provides a working example in the context of networked infrastructure, and concludes with an agenda for future research.

Wide-area breakdowns of infrastructure networks often result from an initial, relatively slow system degradation that eventually evolves into a fast and uncontrollable failure propagation sequence, as has been observed on cascading line outages within electric power grids. In order to study the global dynamics of such failure processes in complex networks we introduce a generic model which considers two stress induced component outage types differing from each other in their time-scale. In the first case the failure is due to an increase in the nodal stress above a critical level and occurs after a small time delay. In analogy to an accelerated ageing process, the second failure type takes the whole history of stress into account. The two failure modes are coupled by simple differential equations. The focus of this paper is set on the influence of different topologies on the progression of the two failure types in time and on the resulting node outage sequence leading to network collapse. Furthermore, the importance of the different model parameters are discussed.

This paper discusses the application of several electricity transmission cost allocation methods to compute natural gas transmission tariffs. Cost allocation methods that have been implemented include four of the most relevant transmission cost allocation methods that have been considered in the electricity sector. These are analyzed both qualitatively and quantitatively. In order to do this, equations modeling the flow of gas in transmission networks have been formulated and solved. Cost allocation principles applied are the same used in electricity. Numerical results corresponding to a 12-node gas network are presented and discussed. Based on this analysis, the paper concludes that transferring some of the methodologies applied in electricity transmission to gas leads to satisfactory results.
