SOAP service’s name:
 RORUTADIS-RepresentativeValueFunction-PUT (see SOAP requests for details)

Description

Robust Ordinal Regression for value-based sorting: RORUTADIS-RepresentativeValueFunction service finds representative function. It is possible to provide an additional optional preference information: example alternatives assignments, assignment pairwise comparisons and desired class cardinalities. Service developed by Krzysztof Ciomek (Poznan University of Technology, under supervision of Milosz Kadzinski).

Inputs

(For outputs, see below)

criteria

A list of criteria (<criteria> tag) with information about preference direction (<criteriaValues mcdaConcept=”preferenceDirection”>, 0 - gain, 1 - cost) and number of characteristic points (<criteriaValues mcdaConcept=”numberOfCharacteristicPoints”>, 0 for the most general marginal utility function or integer grater or equal to 2) of each criterion.

The input value should be a valid XMCDA document whose main tag is <criteria>. It must have the following form:

<criteria>
<criterion id=”[…]” /> […]

</criteria>

<criteriaValues mcdaConcept=”preferenceDirection”>
<criterionValue>
<criterionID>[…]</criterionID> <value><integer>[…]</integer></value>

</criterionValue> […]

</criteriaValues>

<criteriaValues mcdaConcept=”numberOfCharacteristicPoints”>
<criterionValue>
<criterionID>[…]</criterionID> <value><integer>[0|integer greater or equal to 2]</integer></value>

</criterionValue> […]

</criteriaValues>

alternatives

A list of alternatives.

The input value should be a valid XMCDA document whose main tag is <alternatives>. It must have the following form:

<alternatives>
<alternative id=”…”>
<active>[…]</active>

</alternative>

</alternatives>

categories

A list of categories (classes). List must be sorted from the worst category to the best.

The input value should be a valid XMCDA document whose main tag is <categories>. It must have the following form:

<categories>
<category id=”[…]” /> […]

</categories>

performanceTable

The performances of the alternatives.

The input value should be a valid XMCDA document whose main tag is <performanceTable>.

assignmentExamples (optional)

A list of assignment examples of alternatives to intervals of categories (classes) or to a specific category (class).

The input value should be a valid XMCDA document whose main tag is <alternativesAssignments>. It must have the following form:

<alternativesAssignments>
<alternativeAssignment>
<alternativeID>[…]</alternativeID> <categoryID>[…]</categoryID>

</alternativeAssignment> […] <alternativeAssignment>

<alternativeID>[…]</alternativeID> <categoriesInterval>

<lowerBound>
<categoryID>[…]</categoryID>

</lowerBound> <upperBound>

<categoryID>[…]</categoryID>

</upperBound>

</categoriesInterval>

</alternativeAssignment> […] <alternativeAssignment>

<alternativeID>[…]</alternativeID> <categoriesSet>

<categoryID>[…]</categoryID> […]

</categoriesSet>

</alternativeAssignment> […]

</alternativesAssignments>

assignmentComparisons (optional)

Two lists of assignment pairwise comparisons. A comparison from list with attribute mcdaConcept=”atLeastAsGoodAs” indicates that some alternative should be assigned to class at least as good as class of some other alternative (k = 0) or at least better by k classes (k > 0). A comparison from list with attribute mcdaConcept=”atMostAsGoodAs” indicates that some alternative should be assigned to class at most better by k classes (k > 0) then some other alternative.

The input value should be a valid XMCDA document whose main tag is <alternativesMatrix>. It must have the following form:

<alternativesMatrix mcdaConcept="atLeastAsGoodAs">
<row>

<alternativeID>[…]</alternativeID> <column>

<alternativeID>[…]</alternativeID> <values>

<value>
<integer>k</integer>

</value>

</values>

</column>

</row> […]

</alternativesMatrix>

<alternativesMatrix mcdaConcept=”atMostAsGoodAs”>
<row>[…]</row> […]

</alternativesMatrix>

preferenceRelation (optional)

Necessary assignment based preference relation between alternatives.

The input value should be a valid XMCDA document whose main tag is <alternativesMatrix>. It must have the following form:

<alternativesMatrix mcdaConcept="atLeastAsGoodAs">
<row>

<alternativeID>[…]</alternativeID> <column>

<alternativeID>[…]</alternativeID> <values>

<value>
<real>…</real>

</value>

</values>

</column>

</row> […]

</alternativesMatrix>

categoriesCardinalities (optional)

A list of category (class) cardinality constraints. It allows to define minimal and/or maximal desired category (class) cardinalities.

The input value should be a valid XMCDA document whose main tag is <categoriesValues>. It must have the following form:

<categoriesValues>
<categoryValue>

<categoryID>[…]</categoryID> <values>

<value>
<interval>
<lowerBound><integer>[…]</integer></lowerBound> <upperBound><integer>[…]</integer></upperBound>

</interval>

</value>

</values>

</categoryValue> […]

</categoriesValues>

methodParameters

Method parameters.

The input value should be a valid XMCDA document whose main tag is <programParameters>. It must have the following form:

<programParameters>
<parameter name=”strictlyMonotonicValueFunctions”>
<values>
<value><boolean>%1</boolean></value>

</values>

</parameter> <parameter name=”mode”>

<values>
<value><label>%2</label></value>

</values>

</parameter>

</programParameters>

where:

  • %1 is a parameter named “strictlyMonotonicValueFunctions”. This is a boolean. The default value is false.

  • %2 is a parameter named “mode”. It can have the following values:

    • iterative: Iterative
    • compromise: Compromise

    The default value is iterative.
