These two procedures differ in their behaviour pessimistic or optimistic in relation to specific actions incomparable with the reference actions. ELECTRE TRI Assistant is a new module that indirectly helps in the calibration of the model, that is to say that the parameters of the model are fixed by giving some example assignments corresponding to desired assignments or past decisions. The users may indicate intervals for each of these parameters, as well as linear constraints, rather than being forced to indicate precise values for all these parameters.

Furthermore, a module becomes available to determine the alternative subsets of constraints that must be removed to restore the consistency see example in Fig. Bana e Costa ed. Gomes da Silva, J. The general idea is to start with few constraints of the parameter values, adding more inequalities as a product of an interactive learning process about the problem and the method. elrctre

For any information please contact logiciels. For instance, it may be used to sort funding requests according to merit categories e. Then, ellectre shows the sorting that corresponds to these parameter values see example in Fig.
These two procedures differ in their behaviour pessimistic or optimistic in relation to specific actions incomparable with the reference actions. The assignment of any action is based on the comparison of the action and the reference actions by means of the outranking relation.
IRIS Interactive Robustness analysis and parameters' Inference for multicriteria Sorting problems is a Decision Support Software designed to address the problem of sorting a set of actions alternatives, projects, candidates into predefined ordered categories, according to their evaluations performances at multiple criteria. Furthermore, the constraints may be defined indirectly, as indicated in the next item.
The main characteristics or IRIS version 2. The parameter values are inferred by a form of regression from the information contained in the example assignments.
It adds a module to identify the source of inconsistency among the constraints when it is not possible to respect all of them at the same time, according to a method described in Mousseau et al. Unlike conventional procedures that are based upon weighted sums compensatory logicthe two procedures provided by ELECTRE TRI do not admit the possibility of total compensation between the performance of actions according to different criteria.

See example in Fig.

The final outputs of the procedure are: The users may indicate intervals for each of these parameters, as well as linear constraints, rather than being forced to indicate precise values for all these parameters. For each action, it depicts the category corresponding to that combination, as well as the range of categories where the action might be assigned without violating any constraint robustness analysis.

On the other hand, if the constraints are compatible with multiple assignments for the actions, IRIS allows drawing robust conclusions by indicating the range of assignments for each action that do not contradict any constraint.
IRIS implements the methodology presented in Dias et al.
However, the most important outcome may be that the end users will increase the insight on their view of the problem, learn about their preferences, and will possibly modify their opinions.

Aoftware segmentation problem involves examining the intrinsic value of the action [dossier de demande], candidate, project, ELECTRE TRI Assistant is a new module that indirectly helps in the calibration of the model, that is to say that the parameters of the model are fixed by giving some example assignments corresponding to desired assignments or past decisions.
Download Demo Version limited problem sizes: For each category in the range IRIS may also softwsre a combination of parameter values softwarw assigns the action to that category see example in Fig.
