What is a computer-based mathematical model?

AbstractMany researchers feel that one's ability to formulate a mathematical model is more art than science. Even so, modern applied mathematics is centered about the role of the mathematical model. Texts are now available and courses are being taught that introduce the basic principles and methods of mathematical modeling. This paper emphasizes that the resolution of most complex modeling problems, especially those in the policy area, are solved using a computer-based model. Thus, there is a need to stress the often overlooked model development steps of verification, validation, and evaluation. This paper reviews some of the recent research in these areas, and notes that important research in these topics is required to put mathematical modeling on a more scientific basis
