The simplest negative feedback dynamic: a constant upper limit. Used to explore Insightmaker options.
Note: temperature units don't work. The simulation uses dollars to show how the relationships between units. Removing units (making every variable unitless) is also an option.
Clone of Simple Thermostat Example
Learning exercise adapted from Donella Meadows "Thinking in Systems," Part One: Systems Structure and Behavior. The example is a single stock system (room temperature) managed by two competing goal-seeking balancing loops, each of which is attempting to pull the stock to a different goal.

From Evans RG and Stoddardt GL 1990 paper Soc Sci Med 31(12)1347-63 , also published in a book by Evans, Barer and Marmor, Why are some people healthy and others not?: The determinants of population health. To IM-425 We add impacts of spending and a "Thermostat" setting for population health controlling health spending.
