Summary

The idea of a Digital Twin has become ever popular as a way of using computation to improve real systems in a variety of domains. The notion that we can build more than one model of the same thing has taken off dramatically as computer power has increased exponentially to the point where what were once very complex large-scale models often taking hours or even days to run are now possible to implement in a matter of seconds. In this sense, we can run digital models over and over again varying their structure in such a way that we can explore the solution space of the real system using the analogy of the twin. We will outline what we now mean by a digital twin, showing how we can use different kinds of models to increase our understanding of our real systema and enabling us to invent new forms for their future. We will develop these ideas primarily in the context of city planning but extending our twins to different scales, to different models of the same real system but from different vantage points and coupling twins together to develop more comprehensive modelling. We will illustrate examples for London as well as our digital twin for British cities and we will conclude with some speculations on the fact that our future world will be composed of multiple twins, multiple models of the same thing, that are rapidly becoming the norm (Batty, 2024)
