The calling sequence captures the cross-references among the model elements, annd can be derived directly from the graphical representation. Partitioning must satisfy generic similarity in that every element in a a genus must have the same number of calling sequence segments, and all elements in a given calling sequence must belong to the same genus. The hierrarchy must have a monotone ordering i.e. none of the calls between genera in different modules involves forward references. This tree allows us to view the model at different levels of abstraction. The Outline shows the modular structure.
Indentation is used to indicate a sub-module contained in a module.
A more informative representation of the modular structure. Every module and genus name is followed by an informal interpretation or comment in natural language. Application of SM in Model Management Structured modeling is also applicable in the area of model integration. The details for doing so will be left out here. However, factors such as whether two entities are dimensionally consistent and the ordering in which models are manipulated play an important role in determining whether the models are integrated correctly.
