| - | **Binding Variable** - A simulator variable which is linked to two different variables from the calibrator: one which is used when the model is run over simulation time, and a different one for historical time. The //History// tab of the //Variable Information// dialogue is where these links are configured. Binding variables are often base-year variables. Also note that binding variables are //fixed// - their values cannot be set from within a simulator framework - but not all //fixed// variables are binding. See the definition of //fixed// variables. | + | **Binding Variable** - A simulator variable which is linked to two different variables from the calibrator: one which is used when the model is run over simulation time, and a different one for historical time.

| **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.

| - | **LF** - Load Factor | ||
| - | **LF for elec prod capacity** - The load factor is the ratio of the amount of electricity produced by a technology class in a year to the amount of electricity that could be potentially produced if the capacity of the technology class were run for every day of the year 24 hours per day. It is unitless and is a measure of how much electricity demand was dispatched (or assigned) to that technology class in a year. Dispatch in an actual grid of electricity production capacity is done on a minute by minute basis. | + | **Load Factor (LF) for electricity production capacity** - The load factor is the ratio of the amount of electricity produced by a technology class in a year to the amount of electricity that could be potentially produced if the capacity of the technology class were run for every day of the year 24 hours per day.
