Resource / Cost Allocation

In this dialog you specify the proportions of each of the various individual costs which should be recovered from the three main tariffs, Connection Tariff, Rental Tariff and Usage Tariff, when cost-dependent tariffs are used. These proportions govern the way that the shares of these costs, allocated to each Service using a Resource, are split between those Services’ tariffs.

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.

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.

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.

Maintenance Cost

The cost of maintaining one unit of a Resource in its Calibration Period. More generally, the cost for a year or a quarter or a month according to the Cost Period input. Unlike Operations Cost, Maintenance Cost is not affected by the Resource utilisation, i.e., it is charged even if the Resource is not used.

For a consumable resource, maintenance cost is the cost of using one unit, rounded up to a full unit, and generated in the period in which the capacity is installed.

Default: 0.0.

Churn Cost

The cost of churn per unit of a Resource in the Calibration Period, if the Churn Mode is Normal or Inflate Demand. It is not recommended to use this input when the Churn Mode is Inflate Operations Costs, as the cost of churn is then modelled through the Operations Cost.

Default: 0.0.

Connection Cost

The one-off non-capitalised cost of leasing a unit of a Resource in the Calibration Period, e.g., the connection cost of a leased line.

Default: 0.0.

Rental Cost

The cost of leasing a unit of a Resource per period (as defined by the Cost Period input) in the Calibration Period, e.g., the rental cost of a leased line.

For a consumable resource, rental cost is the cost of using one unit, rounded up to a full unit, and generated in the period in which the capacity is installed.

Default: 0.0.

Usage Cost

The cost of using a Resource per period (as defined by the Cost Period input), in its Calibration Period, charged pro-rata on the basis of the used capacity of the Resource.

For a consumable resource, usage cost is the cost of using one unit, in proportion to its actual usage, and generated in the period when the capacity is used.

Default: 0.0.

Operations Cost

The cost of operating a fully-utilised unit of a Resource per period (as defined by the Cost Period input) in its Calibration Period, charged pro-rata on the basis of the used capacity of the Resource.

For a consumable resource, operations cost is the cost of using one unit, in proportion to its actual usage, and generated in the period when the capacity is used.

Default: 0.0.
