On the basis of a study of the papers published in the professional journals of each discipline, distribution depending on whether they deal with the topic of Metamodeling, Modeling, or Implementation can easily be obtained, The use of these three objects of study can be associated with the three levels of the metasystem paradigm (see van Gigch, 19a), where Modeling takes place at the object level, Metamodeling at the metalevel, and Implementation at the lower level of the hierarchy of control levels. Implementation of Models, where the object of study consists of the application and direct use of the models, derived earlier, to the real world.Modeling, where the object of study is the design and formulation of models.Metamodeling provides the epistemological framework for modeling (see below) Metamodeling, where the object of study is the methods which are used to design and formulate models.
In order to provide a comparison of the objects of study of the two disciplines, we postulate the existence of three distinct categories of objects of study: What methodology does each discipline use to meeiĬOMPARISON OF THE OBJECTS OF STUDY OF THE DISCIPLINES What are the objectives of each discipline?ģ.

He maintains that these sciences, by being too closely wedded to a single methodology, are restricting their innovative and creative thrust.
