The SIMPOP Project

Scientific Position



The Simpop project is a joint collaboration between scientists in geography and computer science. It has been the first application of multi-agents systems in geography (Simpop1, 1996). Thanks to advances in computing power and higher expressiveness of programming languages and libraries, an improved model has been developed (Simpop2, 2006).

Through multi-agent modeling of cities systems evolution, geographers and computer scientists are tackling questions like:
  • What makes us think of systems of cities as complex systems ?

  • To what extents are they self-organised, can they be controlled ?

  • Which cities will rise or decline during the next decades ?

  • Can cities escape from general trends through clever governance ?

  • Are global cities an innovation of the 20th century ?

  • What is comparable in the evolution of cities in countries as different as United States and South-Africa ?

The SIMPOP platform is a geosimulation tool for exploring the future of cities and reconstructing their past dynamics.

Common features in the genesis and long-term evolution of cities help in understanding and predicting their future dynamics. Because of the multiple linkages and interactions which sustain these dynamics, modelling their evolution requires computer simulation.

The evolutionary processes common to all urban system are integrated in a Simpop2 Generic Model which reconstructs the spatio-temporal dynamics of a system of cities over several centuries. Several instantiated models are applied to a variety of countries illustrating four types of urban genesis in the world (Europe Long Term, United States, South Africa, India) and to predictive scenarii (Eurosim).

The research has been supported by several programs of the European Commission and a program from the french ministry of research and the CNRS (see the Credits and partners page for details).
