QSIM2: A low-budget heuristic approach to modeling and forecasting

Abstract This paper contains a description of a simple mathematical framework and modeling process which can be used to study a large class of socio-techno-natural systems. Models may be designed using intuitive notions or data to help specify the variables, parameters and interrelationships, which, with the aid of a computer program, can be used to forecast system behavior under various assumptions. Two example models are described.
