System Dynamics Modules

First Order Non-Linear Self-Referencing—Flowing In

This goal setting module is self-referencing, the reference level being set by Maximum Possible Value of ‘S’, which is applied as an exogenous constraint. For example, this might be a consequence of finite capacity of an area to sustain a population. The actual state variable ‘S’ STATE OF THE SYSTEM is continually monitored as a measure of relative density, that is, Actual ‘S’ Divided by Maximum ‘S’. This indicates proximity of actual state to maximum possible. In self-referencing systems, the system is highly sensitive to the maximum possible value of S.
