Computes necessary and possible preference relations for the pairs of DMUs (alternatives) using Additive Data Envelopment Analysis Model with hierarchical structure of inputs and outputs.
(For outputs, see below)
A list of alternatives (DMUs).
A list of alternatives (DMUs) performances (on leaf hierarchy criteria).
Tag: performanceTable
Code:
<performanceTable>
<alternativePerformances>
<alternativeID> [...] </alternativeID>

<value>[...]</value>
</performance>
[...]
</alternativePerformances>
[...]
</performanceTable>
A list of performance criteria (hierarchy leafs) and their preference direction. List has to contain at least one criterion that will be minimized (input) and at least one criterion that will be maximized (output) for each hierarchy category.
