Systems dynamics is a simulation method that allows us to understand complex behavior of a system of equations. SD allows us to explore complex behavior that results from feedbacks in a system. The system may be at the molecular level (molecular dynamics), the cellular level (metabolic pathways), the organismal level (homeostasis), the ecosystem level (food webs) and the global level.
ECOME is a model of an evolving consumption web, combining the equations for a food web with those of genetic evolution. The statbility of an ecosystem can be explored in the context of inequality in the rate of evolution or adaptation. ECOME movie
World 4 is a model for human population dynamics as humanity undergoes technology-driven hyperexponential explosion in the context of a finite planet.
