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.
Grade of Service
The grade of service parameter required in the Erlang B formula. This represents the probability of blocking on a Service, typically of the order of 0.001 for a fixed network.
Default: 0.0. This must be set to a non-zero value.
