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
