Function / Other Details

Functions represent the function that different types of Resource perform.

Capacity

Capacity Unit

The unit of capacity, e.g., Circuits, Connections, Lines. Either type a unit or choose from the drop-down list.

The selection has no mathematical effect on the model, but the text is used to label the y-axis on results graphs.

Default: None.

Resources

The Resources listed are those that perform the selected Function.

Double-clicking on the name of a Resource opens the data entry dialog associated with it.

You can also insert new Resources into the Function, or rename or delete existing ones from within this box.

See 4.4 Working with model elements, icons, links and text boxes

Other Details

Label

The text used to identify an element in the Results program when selecting elements to draw on a graph and for labelling the subsequent graphs. If the Label is blank, the element name is used instead.

You can group a number of sensitivity parameters by giving them all the same Label. They will then be treated as a single group in the Results program.

There is also a global Label field which is just used within the Editor as an overall description for the model.

Default: none.

Age Based Charging

A choice for a Function, governing the way that Transformations, representing Resources in that Function, allocate the costs of secondary Resources (those installed by such Transformations) back to Services.

No: secondary Resources are installed on the basis of the total installed or used capacity of a primary Resource, and the secondary costs are allocated back to Services on the basis of their total usage of that primary Resource.

Yes: secondary Resources are installed on the basis of the installed or used capacity of each separate age of a primary Resource, and the secondary costs – then identified with each primary age – are allocated back to Services on the basis of their usage of the respective ages of the primary Resource.

Note: The costs of primary Resources are always allocated back to Services or Transformations on the basis of the respective used capacities of each age. Propagating this identification through a Resource Transformation requires significant additional memory, and is only really necessary when modelling tightly-bound primary and secondary Resources with secondary Age Factors and a significant flux in demand.

Default: No.

Switched Off

A choice governing whether a service, resource, transformation or function is excluded from the model, in order to study the effect of its removal.

No: the element is included in the model.

Yes: the element is excluded from the model.

Default: No.
