the quantitative model​

Sagot :

Answer:

Qualitative and quantitative modelling are key concepts in system dynamics. Quantitative models are compact representations where a single differential or difference equation may describe the performance of the system for a large set of input functions and initial states (Lunze, 1998). Qualitative models do not require mathematical formulism, but are used to “draw, diagram or represent visually ideas, hunches, perceived patterns or relationships between parts of their projects, discoveries in their data…and so on” (Richards, 1999).
