Balancing Tree
The idea behind tree balancing is the balancing of indicator and
category weights.
The weight allows specifying the relative importance of
the indicator or category.
- For instance, if indicator A has a weight of 3 and indicator B
has a weight of 7, then we know that B is two times more important
than A.
Another rule is that the sum of all weights on the same level
and within the same category must be 10. Of course, it might be 100
or 10000 or 5, but it has been found that to get the best results
in representing the relative importance of the items, it is better
to specify weights on a 0-10 scale.
Changing weights
If you click on any category or indicator, you will see the
setting panel below. You can change the weight from 1 to 10.
What if you have tree indicators - A (weight 2), B (weight 5)
and C (weight 7) - within the same category? The sum of the weights
is more than 10.
If the sum of the weights is more than 10 (or if it is less than
10), you should change the weights to comply with the weight sum
rule. You have two options to do this:
- You can change the weights manually;
- You can select the Balance Tree
 command in the Strategy Tree menu.
In fact, you have a third option: you can leave the weights
as-is, but in this case, the total performance value might be more
than 100%.
