This paper presents a new method for multiple criteria ordinal classification (sorting) problems. This type of problem requires the different classes or categories to be pre-defined and ordered, from the best to the worst or from the worst to the best. The actions (not necessarily known a priori) are assigned to the different ordered classes. Several ELECTRE type methods were designed to deal w...

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,...

Outsourcing plays an important role in the success of organizations. One of the risks associated with outsourcing is inappropriate contractor selection which significantly influences the implementation of projects in terms of time, quality, and cost. In this study, we applied multi-criteria decision-making techniques in order to determine the best contractor using criteria such as reputation, o...

Picture fuzzy set (PFS) is more comprehensive tool than intuitionistic (IFS) for modeling the uncertain decision-making problems. In this paper, a new picture entropy measure proposed and proved that satisfies axiomatic definition of measures sets. Besides this, useful mathematical properties are also investigated. The justification established by discussing its particular cases compares it wit...

ELECTRE TRI is a set of methods designed to sort alternatives evaluated on several criteria into ordered categories. The original method uses limiting profiles. A recently introduced method uses central profiles. We study the relations between these two methods. We do so by investigating if an ordered partition obtained with one method can also be obtained with the other method, after a suitabl...

This paper proposes a novel approach to cope with the multi-criteria group decision-making problems. We give the pairwise comparisons based on the best-worst-method (BWM), which can decrease comparison times. Additionally, our comparison results are determined with the positive and negative aspects. In order to deal with the decision matrices effectively, we consider the elimination and choice ...

The intention of this article is to perform a brief analysis of portfolio management in Brazil, using research conducted by the Project Management Institute through pmsurvey.org, which provides consolidated information on how companies plan and manage their portfolios and projects. Based on the identification of latent need for improvement in the portfolio management process, this study propose...

Decision making in an uncertain environment is a complex task for decision makers. Fuzzy multi criteria decision making methods are proposed in the literature where the subjective criteria and the weights of all criteria are assessed in linguistic variables since conventional methods cannot take into consideration the subjectivity and uncertainty in the decision process. Fuzzy ELECTRE I (Elimin...

Several interactive methods exist to identify nondominated solutions in a Multiple Objective Mixed Integer Linear Program. But what if the Decision Maker is also interested in sorting those solutions (assigning them to pre-established ordinal categories)? We propose an interactive ‘‘branch-and-bound like’’ technique to progressively build the nondominated set, combined with ELECTRE TRI method (...
