Weight

Weighted share of the demand stratum in the total demand of all demand strata of the activity pair

In the case of coupling on both sides, weights must be indicated at each demand stratum of the activity pair. If all weights are set to 0, each demand stratum receives the same share.

Note

This value is only relevant for all demand strata of the activity pair if the couple jointly on both sides option is selected for an activity pair. The value Constraint orig. of all demand strata that use the activity pair is set to the value of the first demand stratum of this activity pair on the Constraints tab page.

Calculate weights

Use the button to calculate the individual weights of the demand strata in the total demand.
