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.
Production Function
A choice of whether the Capital Cost Structure of a Resource may change in time as individual Cost Index Cost Trends vary.
Zero Elasticity: the proportion of the Capital Cost associated with each Cost Index in the Calibration Period remains constant throughout the model run.
Cobb-Douglas: the unit Capital Cost is minimised in other years through substitution between increasing and decreasing trends, by varying the proportions associated with each Cost Index.
Default: Zero Elasticity.
Use Average Connections
A choice of how connections are used to calculate various Service results.
No: end-of-year connections are used for all calculations, maintaining compatibility with versions of STEM prior to STEM 5.0.
Yes: the average number of connections over a year is used to calculate Annual Traffic, as well as Rental and Usage Revenues.
Default: Yes.
Pre-Run Installation
A choice governing the installation of equipment in the first period of the model run.
Yes: a range of different ages of each Resource are installed according to the respective per-Resource Installation Profiles.
No: the profiles are disregarded and all equipment is installed brand new.
Default: No.
Cost Breakdown (1)
A choice of whether STEM generates the Service allocated cost results broken down by individual contributing Resources.
None: allocated cost results are not broken down by individual Resources.
Opaque: allocated cost results are limited to a single layer of the network. In this mode, an intermediate Service presents a sub-total of all costs allocated from any secondary layers.
Transparent: allocated cost results are stored for all Resources that contribute costs to a given Service.
Default: None.
