In ELECTRE methods, the construction of an outranking relation amounts at validating or invalidating, for any pair of alternatives (a; b), the assertion ‘‘a is at least as good as b’’. This comparison is grounded on the evaluation vectors of both alternatives, and on additional information concerning the decision maker s preferences, accounting for two conditions: concordance and non-discordanc...

Outranking relations such as produced by the Electre I or II or the Tactic methods are based on a concordance and non-discordance principle that leads to declaring that an alternative is “superior” to another, if the coalition of attributes supporting this proposition is “sufficiently important” (concordance condition) and if there is no attribute that “strongly rejects” it (non-discordance con...

. ABC analysis is one of the most widely used techniques in inventory management to classify items into three ordered categories called A, B and C, where category A contains the most important items and category C includes the least important ones. The ABC classification of inventory items is based on their performance expressed by weighted scores. In this paper, a new ABC classification model ...

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...

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...
