Inputs beginning with ‘V’

Validity

The number of years, including the current period, over which incremental units are summed in order to determine the quantity for pricing purposes.

The incremental cost is the difference between the price read off from the Price List for this total quantity, less the price for the units already installed within the number of years defined by the validity of the Price List.

Default: 1.0.

Value

The value in the specified period. You can enter values without a period: STEM will automatically create a period one year, quarter or month after the last period in the series.

Default: 0.

Value A

The value in Period A. This is the first reference point for the series.

Default: 0.

Value B

The value in Period B. This is the second reference point for the series.

Given the two specific reference points for the series, STEM fits an S-shaped curve through these two points to match the Saturation level and Base Period. If the first value is greater than the second, you can define a curve that starts at the Saturation level, and then falls, representing a declining Service.

Default: 0.

Value Chain

A choice of whether revenues generated by a Service, or costs incurred by a Service, are passed back as costs to a Transformation driving that Service, in order to perform a value chain analysis.

None: there is no cost linkage between the Service and a Transformation which defines the demand for the Service.

Commodity: if the Customer Base for the Service is defined as a reference to a Resource Transformation, revenues from this Service appear as additional costs for the Resource, which will be allocated in turn to further Services using that Resource.

Cross Charge: if the Customer Base for the Service is defined as a reference to a Resource Transformation, costs allocated to this Service will be allocated in turn to further Services using that Resource.

Default: None.

Variable Annual Prop.

Defines a variable annual administrative fee, paid at the start of each year during the term (except for the first year). This is specified as a percentage of the unused credit (where a maximum is defined).

Default: Constant {0.0}.

Variable Start Prop.

Defines an up-front variable fee, defined as a proportion of the new credit each year.

Default: Constant {0.0}.

Variants

The Variants box lists all the Variants which are defined within the selected Dimension or Template. You can double-click on one of the Variant names to display the corresponding Variant Data dialog, showing the parameters associated with that Variant.

See 9.3 Working with scenarios and 9.5 Managing complexity with template replication.

Default: none.
