Software based on the principles of complexity CityASim has been developed on the basis of principles of Complexity. The structure of CityASim is based upon cells that represent the built environment, the land use type, in other words the function of the cell. Unlike the natural world, structures (and non-build space) in the human environment are a product of human purposes. In addition flowing through the cells, driving their changes, are humans and their actions, their metabolism.
CityASim uses economic principles of self-regulating markets CityASim uses economic principles of self-regulating markets, where the price and consumer behaviour stimulates the self-regulation. The cells are placed on a rectangular grid, where they interact with other cells on the basis of connections between them established through the market mechanisms and on the basis of processes inside them. This method is based on Cellular Automata, with various extensions to allow long range connectivity as found in cities. The connections between the cells effectively form networks between the cells on the basis of characteristics of each cell. For instance, through the operation of four market mechanisms (product, service, employment, and property markets), a residential cell will connect to an employment cell to get work and income, and to retail and service cells to purchase food and other goods, and obtain a range of services, including utilities, education, and others. Thus, the market mechanisms will stimulate the creation of networks and links are formed only if transaction costs are acceptable (the equi-marginal principle).
As result of simultaneous operation of various processes in CityASim, the following emergent behaviour will occur in the model: Please contact Savannah for aditional sales and pricing information.
