| **Conceptual Hierarchy** - is a hierarchical structure consisting of nodes that is used to organize information pertaining to a framework. The highest level node is the framework itself; a framework may have one or more sub-framework nodes, and sub-framework nodes may have one or more sub-framework nodes and/or one or more calculators | **Conceptual Hierarchy** - is a hierarchical structure consisting of nodes that is used to organize information pertaining to a framework.

| **Control Space**- In the design approach, processes are separated into two classes: those that transform information and those that transform energy and material. Models of processes dealing only with information-and these include decision processes -occupy the control space of systems theory, while models of processes dealing with energy and material occupy machine space, but with their control function linked to control space).

| + | **Database model** - a model (or //framework//) which runs over an observed historical period, usually with the purpose of assembling an internally-consistent historical database. Its conceptual purpose can be the same of a //calibrator// framework except that a database model is not linked to a counterpart //simulator// framework. | ||
| **Dependency Structure** - represents the flows of information among the calculators of a framework and takes the form of an acyclic graph. The computational sequence of calculators may be inferred from the dependency structure. | **Dependency Structure** - represents the flows of information among the calculators of a framework and takes the form of an acyclic graph.
