On the qualitative properties in system dynamics models*

چکیده
– This paper proposes that the concept of ‘qualitative’ developed around the qualitative theory of nonlinear dynamical systems be applied to the field of system dynamics in order to provide a more solid foundation for the use of the qualitative in this field. The advantages of the use of qualitative concepts are analyzed both from a conceptual and an operational point of view. A preliminary stage in the world modeling process is used to illustrate this proposal.
