Understanding the past with Agent-based Models

Posted on Thursday 29 September 2016 by Andrew Crooks

I have had a long fascination with the use of agent-based modeling (ABM) to explore past cultures and civilizations. There are a number of very good models which I will not do justice to in a single post, unless I write a very very long one. Some works…

About CA Modelling

Posted on Friday 28 September 2012 by Michael Batty

Amin Tayyebi, a Graduate Research Assistant in the Department of Forestry and Natural Resources at Purdue University, asked me to make a short (<5 minute) movie about Cellular Automata Modelling so that he could put it into a series about … Continue reading →

Simulating Infectious Diseases in Large Cities

Posted on Thursday 19 January 2012 by Michael Batty

We published quite a high profile paper this week in The Lancet Infectious Diseases. Anders Johansson, myself and colleagues wrote a speculative paper on how to generalise the dynamics of SIR (spatial epidemics) models from pedestrian crowding models as part … Continue reading →

Simulating Employment Location

Posted on Sunday 8 January 2012 by Michael Batty

As part of our ARCADIA project, we are taking employment forecasts for different sectors from Cambridge Econometrics input-output model, and then simulating location using two-stage regression. This in turn provides the inputs to our LUTI models. There is detail of the … Continue reading →

FuturICT

Posted on Thursday 6 October 2011 by Michael Batty

is a project led by ETH Zurich and UCL which deals with the simulation of highly interconnected coupled social systems characterised by extreme events and fast dynamics: i.e. things that go on in Cities. See it on Vimeo, explore the … Continue reading →

Geosimulation

Posted on Monday 26 September 2011 by Michael Batty

Tweet Geosimulation is the term first used for modelling geospatial systems by Benenson and Torrens where the models in question focus on agents, objects, cells and patterns. Marceau & Benenson present a snapshot of the state of the art in … Continue reading →

Why Agent-Based Modelling?

Posted on Wednesday 21 September 2011 by Michael Batty

Tweet Andrew Crooks notes the work of Doyne Farmer with Rob Axtell on ABMs for housing markets which pointed to an article by Rob on Why Agents? More on these ideas in our edited book Agent-Based Models of Geographical Systems published by … Continue reading →

Is Digital Simulation the Same as Physical Experimentation?

Posted on Friday 12 August 2011 by Michael Batty

Simulation models test theories against data we cannot reproduce in the physical environment their theory relates to. We cannot experiment on the real thing. But how different are simulations from experiments? In Science in Age of Computer Simulation, Winsberg presents … Continue reading →
