The term model is polysemous. It refers to concrete objects, which are chosen or made through the techniques of arts, crafts, and engineering, as well as to abstract constructions, which are built by formal, theoretical, and statistical means for descriptive, explanatory, and normative aims. The term is also extended to the effective procedure by which scientific activity may be carried out according to rules, by which it can be considered valid in order to provide knowledge.
