Concepts of Modelling

Publisher Summary This chapter reviews the modeling theory and its application in the development of models. It discusses model components as well as modeling steps, which include model conceptualization, mathematical formulation, parameter estimation and calibration, sensitivity analysis, and validation. Various methods to select “close to the right” complexity of the model are presented. Several model formulations are always available, and to choose among these requires sound scientific constraints to be imposed on the model. Many different model types with different advantages and disadvantages are available. The selection of the best model type for well-defined ecological or environmental management problems are discussed in the chapter.
