If a factor for the lower or upper production or attraction limit is not a constant value, i.e. a specific value counts for each zone, then you need to define - for all zones and for all demand strata - its values with constraint type Weak or Elastic (Defining constraints) in the zone list (Editing the properties of objects in lists).
|
Tip: If you make the appropriate setting before opening a zone list (Setting list options), Visum will automatically create some list layout files when a zone list is opened. Using these files, you can quickly view the most important demand data. |
1. Open the Zones list (Opening a list).
2. From the selection list, select the pre-defined list layout EVA constraints.
For each demand stratum, columns with the corresponding factors are listed.
3. Edit the factor values for the desired zones and demand strata (Editing the properties of objects in lists).
|
Note: The values from the zone list are not taken into account for constant factors. |
