Service / Tariffs

Tariffs can be wholly dependent on the costs or wholly independent of them. In this dialog you set the tariffs that are independent of the costs.

Select the button to access the time-series dialog associated with each one.

Connection Tariff

The one-off tariff charged per new connection to a Service.

Default: cost independent and Constant {0.0}.

Note: The simple Tariffs dialog just shows the Cost Independent Tariffs, which are also shown in the more detailed Cost Dependent Tariffs dialog.

Features See Tariffs and revenues.

Rental Tariff

The tariff charged per period (defined by Tariff Period input) per connection to a Service.

Default: cost independent and Constant {0.0}.

Note: The simple Tariffs dialog just shows the Cost Independent Tariffs, which are also shown in the more detailed Cost Dependent Tariffs dialog.

Features See Tariffs and revenues.

Usage Tariff

The tariff charged per unit of traffic. For example, if the Traffic Unit is Call Minutes, the Usage Tariff is the tariff charged per minute.

Default: cost independent and Constant {0.0}.

Note: The simple Tariffs dialog just shows the Cost Independent Tariffs, which are also shown in the more detailed Advanced/Cost Dependent Tariffs dialog.

Features See Tariffs and revenues.

Units

Global Currency Unit

The unit for all monetary inputs to the model, e.g., DM, Dollars, Pounds, Yen. Either type in a unit or choose from the drop-down list. Currencies are listed alphabetically by full currency name; each name is followed by the appropriate three-letter ISO code(s). For example, Francs is followed by BEF, CHF and FRF. STEM performs no currency conversions, and any changes in a dialog will be applied globally.

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

Default: none.

Features See Network, Financial statements.

Tariff Period

Defines a reference period for the Rental Tariff input (which is interpreted as tariff per tariff period, such as EUR per month or USD per annum). This indicates how the tariff input should then be scaled in proportion to the length of the current period for calculation.

Default: Year.

Note: The simple Tariffs dialog just shows the Cost Independent Tariffs, which are also shown in the more detailed Cost Dependent Tariffs dialog.

You may also want to levy a Churn Tariff for customers disconnecting and reconnecting – see the Service / Other Details dialog.

It is also possible to model a partly cost-based tariff policy, or the gradual transition to or from a cost-based policy, using a time series for the Independence Weighting which is set in the Service / Cost Dependent Tariffs dialog.
