All the following have a common characteristic.

Introduce the concept of modeling and simulation.

This Romeo and Juliet Model was adapted by Geoff McDonnell from Michael J Radzicki (1993) Dyadic processes, tempestuous relationships, and system dynamics, System Dynamic Rev. 9 (1) :79-94

The model construction process is actually a balancing loop which endeavors to employ an abstract version of real events to form a model which produces conclusions and behavior which mimic the real events.

Introduce the concept of modeling and simulation.

This common archetype of systems that include relapse or recidivism allows exploration of the unintended effects of increasing upstream capacity and swamping downstream capacity. The increase in the relapse rate eventually returns to swamp upstream capacity as well. A social welfare example, based on a TANF case study, from How Small System Dynamics Models Can Help the Policy Process. N. Ghaffarzadegan, J. Lyneis, GP Richardson.
