In this thesis a method for risk classification in the information security domain is described. Using a set of classification examples, an ELECTRE TRI multi-criteria decision aid model is constructed. This model is capable of classifying organizations in risk classes based on company characteristics and results of technical assessment. The construction process of this model consisted of gather...

In this paper the authors carry out a multiple criteria evaluation of 40 characteristics of e-learning platforms, in order to find the most suitable to meet the needs of an e-learning course for higher schools with Agricultural and Forestry content. The evaluation data came from a Delphi survey method, where experts’ opinions are reflected. These data were introduced in ELECTRE III, a multi-cri...

Often decisions taken in organizations are made by a group of people, and in order to build a collective decision, the preferences of individuals must be considered. The two most useful approaches to aggregating individual preferences are the aggregation of individual judgments and the aggregation of individual priorities. This paper focuses on the latter approach and proposes a multicriteria g...

The project of construction barriers removal is a comprehensive planning task and it demands suitable support for identification, priority ranking facilities necessary removal. This paper proposes multicirteria Intuitionistic Fuzzy (IF) ELECTRE model to decision makers in the process managing physically disabled high schools. IF approach used deal with complex problems, where decision-makers ha...

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,...

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...

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...

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 (...
