National infrastructure systems spanning energy, transport, digital, waste, and water are well recognised as complex and interdependent. While some policy makers have been keen to adopt the narrative of complexity, the application of complexity-based methods in public policy decision-making has been restricted by the lack of innovation in associated methodologies and tools. In this paper we firstly evaluate the application of complex adaptive systems theory to infrastructure systems, comparing and contrasting this approach with traditional systems theory. We secondly identify five key theoretical properties of complex adaptive systems including adaptive agents, diverse agents, dynamics, irreversibility, and emergence, which are exhibited across three hierarchical levels ranging from agents, to networks, to systems. With these properties in mind, we then present a case study on the development of a system-of-systems modelling approach based on complex adaptive systems theory capable of modelling an emergent national infrastructure system, driven by agent-level decisions with explicitly modelled interdependencies between energy, transport, digital, waste, and water. Indeed, the novel contribution of the paper is the articulation of the case study describing a decade of research which applies complex adaptive systems properties to the development of a national infrastructure system-of-systems model. This approach has been used by the UK National Infrastructure Commission to produce a National Infrastructure Assessment which is capable of coordinating infrastructure policy across a historically fragmented governance landscape spanning eight government departments. The application will continue to be pertinent moving forward due to the continuing complexity of interdependent infrastructure systems, particularly the challenges of increased electrification and the proliferation of the Internet of Things.

Smartphones, with their “pervasive presence” in contact with our bodies, have come to act as sensory prosthetics that mediate our experience of the city. They activate new possibilities of navigating the urban, such that we can find exactly what we want, rather than what has been placed before us. This article argues that smartphone technologies produce a more fluid engagement with urban space: where space is not so much “given” as “enacted.” In this context, notions of “legibility” take on new algorithmic and virtual forms. Thus, according to Hamilton and colleagues, where “the legible city waited to be read, the transparent city of data waits to be accessed.” Here, stable features dissolve as urban space becomes increasingly fluid and contingent, no longer limited by static patterns of inhabitation. Instead, how we move and where we move shift in accordance with the kinds of urban resources being activated at any given location, at any given moment, and in conjunction with the shifting vicissitudes of the crowd. In this context, the virtual (in its technological definition of cyber-enabled or -enacted space) mediates and activates the virtual (in its philosophical definition pertaining to the capacities of an entity that may or may not be manifested depending on context). The article considers the implications of this novel spatial mediation using an ontological perspective informed by complex adaptive systems theory, which considers forms and objects not as absolutes but rather as contingent entities activated through interactions.

Health care systems across the world are in a state of flux. If the experience of the early 1990s can be used as a model, the recent global economic downturn will lead to very significant pressures to reduce spending and achieve better value. Systems have provided a range of approaches to modeling and evaluating these more complex organizations, from simple process models to complex adaptive systems. This paper considers the pros and cons of such approaches and proposes a new modeling approach that combines the best elements of other techniques. This paper also describes a case study, where the approach has been deployed by the authors. The case study comes from health care services in Ontario, Canada, who are shifting from the traditionally hospital-based system to one that recognizes a greater role for community and primary care services.

The trend toward convergence, initiated by advances in ICT, entails the creation of new value chain networks, made up by partnerships between actors in unrelated industries. Such a process of convergence, however, can create a new dimension of network complexity, precipitating dynamic behavior among actors. In this paper we seek to understand how different actors in value chain networks have co-evolved in practice with the development of convergence services. Interpretative case studies on two different converged services in Korea (mobile banking, and One phone services) are undertaken to examine how different actor network adapted in different ways to shape the overall complexity of the converged service. The case study analysis is innovative in being conducted within a combined framework of Complex Adaptive Systems and Actor Network Theory. This synthesis offers a way to characterize the drivers of co-evolutionary behavior, capturing the translation processes undergone by actor networks.
