IRIS - Interactive Robustness analysis and parameters' Inference for multicriteria Sorting problems Version 2.0 User Manual

چکیده
This document is the User Manual for the decision support software IRIS Interactive Robustness analysis and parameters' Inference for multicriteria Sorting problems (Version 2). This tool has been built to support the assignment of actions (alternatives, projects, candidates) described by their evaluation (performance) at multiple dimensions (criteria) to a set of predefined ordered categories, using a pessimistic concordance-only variant of the ELECTRE TRI method. Rather than demanding precise values for the ELECTRE TRI parameters, IRIS allows to enter constraints on these values, namely assignment examples that it tries to restore. 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. On the other hand, if the constraints are compatible with multiple assignments for the actions, IRIS allows to draw robust conclusions by indicating the range of assignments (for each action) that do not contradict any constraint.

Interactive Search for Compromise Solutions in Multicriteria Graph Problems
In this paper, the purpose is to adapt classical interactive methods to multicriteria combinatorial problems in order to explore the non-dominated solutions set. We propose an interactive procedure alternating a calculation stage determining the current best compromise solution and a dialogue stage allowing decision maker to specify his/her preferences. For the calculation stage, we propose an ...
متن کاملComposite Strategy for Multicriteria Ranking/Sorting (methodological issues, examples)
The paper addresses the modular design of composite solving strategies for multicriteria ranking (sorting). Here a " scale of creativity " that is close to creative levels proposed by Altshuller is used as the reference viewpoint: (i) a basic object, (ii) a selected object, (iii) a modified object, and (iv) a designed object (e.g., composition of object components). These levels maybe used in v...

Introduction: The subject of this research is having healthy air and its challenge is air purification to have this type of air. Healthy air is free of any pollutants, including odors, harmful gasses, dust, and viruses, especially corona. This healthy air is provided by a purifier device. One of the problems of metropolises is the lack of healthy air, which is one of the most important human ne...
متن کاملA taxonomy of clustering procedures
In the field of multicriteria decision aid, considerable attention has been paid to supervised classification problems, especially to so-called sorting problems, where an order is assumed on the predefined classes. Recently, some non-supervised multicriteria classification procedures, also known as multicriteria clustering procedures, have been proposed aiming to discover data structures from a...
متن کاملGeneralized Interactive Algorithm of Multicriteria Optimization*
In the interactive algorithms for multicriteria optimization the decision maker (DM) may express his/her preferences among the separate Pareto optimal solutions with the help of the values of the scalarizing problem parameters. The DM must choose the final (most preferred) solution and be responsible for this selection. The interactive methods are the best developed and wide spread methods. Thi...
