Document Summary
What are urban sustainability models: specifying and mathematically relating key variables in ways that allow for simulating the coupling of human and social processes to project future states. Formalized = use ideas in equations that tie into real data and are computed, resulting in a simulation as the output. Models are another way of scientific knowing: Build then validate (calibrate) against reality: benefits of formalized models. 1st/2nd generation spatial models: gravity models. Demonstrate how population and resources move (as if by gravitational attraction) in response to changes in land use. E. g. how demographics and data might change for area with a single, central hospital vs. multiple hospitals sprinkled throughout the area: site suitability overlay models. 3rd generation dynamic and spatial models: agent-based models: a bottom-up model that simulates the interaction of agents at time steps, as described by rules invented by the modeler.
