System Dynamics Pitfalls and Pointers
Assuring Integrity of Units Used In Models
Building sound models demands units be assigned reliability and consistently
through every stage of construction. Regardless of how tempting and
expeditious it might initially appear to build models without assigning
units, dimensionless models should be avoided. Powersim Studio has been
designed to assure consistent assignment of units at every stage
of construction. Even for an experienced modeller, it may not
be always clear what units are to be assigned at
a particular stage of construction. However, there are some simple
techniques which enable us to determine which units are to
The following explains how to assure the integrity of
units used in system dynamics models .
