Abstract
This paper addresses some problems and progress in the develop ment of mathematical simulation models in which the mathe matical relations are not fully understood — in particular, models of biological systems. Three types of utility of models are defined, as are sharp and fuzzy laws. With these concepts in mind, models of various sizes are discussed. Modeling is analyzed from the point of view of making concepts specific, of sharpening fuzzy laws, and of producing useful results. The practical difficulties encountered when a team of experts in different fields attempt to develop a model are considered. Finally, the question of cost is addressed vis-à-vis the benefits that can accrue as a result of modeling activity.
