Information and How a City Works Colin Harrison Perspective on Cities A city is collection of processes – public, enterprise, and personal - that are founded on the natural and built environments, that are driven by and are intended to support the needs of the inhabitants, and that produce and consume various resources and social outputs. These processes are mediated by flows of information. The collection of processes is a complex system operating on multiple spatial and temporal scales. Information Engineering for Cities To design, construct, operate, manage, and maintain a set of systems (machines) that make the city’s processes as effective as possible at supporting the short-term and long-term needs of its citizens for… …safety …economic development …efficiency (cost, reliability, capacity…) …accessibility (ease of use, choices, flexibility…) …resilience (acute threats, long-term threats, unknown threats, social cohesion…) Some of these systems will be centralised and some will be decentralised.
