Data / Cost Trends

In this series of data boxes, you represent how you believe overall Cost Trends for Services and Resources will change over the course of the model run. The trends you specify apply to every Service or Resource cost in the model. You can also specify Cost Trends individually for each Resource. The final Cost Trend for a Resource is calculated by multiplying the overall and individual Running Cost Trends together. Trends are normalised to 1 in the Calibration Period of the Service or Resource.

Service Costs

The calibration values you set for Administration and Provision Costs in the Calibration Period (set in the Administrative Costs dialog for each Service) are used as starting points for these trends.

Administration Cost Trend

This is applied to the Administration Cost calibration value you set for each Service in the Administrative Costs dialog.

Default: Constant {1.0}.

Provision Cost Trend

This is applied to the Provision Cost calibration value you set for each Service in the Administrative Costs dialog.

Default: Constant {1.0}.

Resource Costs

The initial values for the Resources are set in the Costs dialog for each resource.

Capital Cost Trend

This is applied to the calibration value you set for Capital Cost in the Resource/Costs dialog.

Default: Constant {1.0}.

Residual Value Trend

This is applied to the calibration value you set for Residual Value in the Resource/Costs dialog.

Default: Constant {1.0}.

Maintenance Cost Trend

This is applied to the calibration value you set for Maintenance Cost in the Resource/Costs dialog.

Default: Constant {1.0}.

Churn Cost Trend

This is applied to the calibration value you set for Resource Churn Cost in the Resource/Costs dialog.

Default: Constant {1.0}.

Decommissioning Cost Trend

This is applied to the calibration value you set for the Decommissioning Cost in the Resource/Costs dialog.

Default: Constant {1.0}.

Connection Cost Trend

This is applied to the calibration value you set for each Connection in the Resource/Costs dialog.

Default: Constant {1.0}.

Rental Cost Trend

This is applied to the calibration value you set for Rental Cost in the Resource/Costs dialog.

Default: Constant {1.0}.

Usage Cost Trend

This is applied to the calibration value you set for Usage Cost in the Resource/Costs dialog.

Default: Constant {1.0}.

Operations Cost Trend

This is applied to the calibration value you set for Operations Cost for each resource in the Resource/Costs dialog.

Default: Constant {1.0}.
