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...

A number of recent papers have investigated the foundations of methods allowing to sort multi-attributed alternatives between several ordered categories. This paper has a similar objective. Our analysis uses a general conjoint measurement framework, encompassing most sorting models used in MDCM, that was proposed in the literature. Within this framework, we provide an axiomatic analysis of what...

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

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...

. 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 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...

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...

Using improvements to the recently published m-polar fuzzy set (mFS) elimination and choice translating reality-I (ELECTRE-I) approach for calculating criteria weights, selection of a Non-Traditional Machining (NTM) process problem from industry is solved in this research. The weights ELECTRE-I method are evaluated using Analytical Hierarchy Process (AHP) Revised Simos' method. For ELECTRE fami...

A new hesitant fuzzy set (HFS)-ELECTRE for multi-criteria group decision-making (MCGDM) problems is developed in this paper. In real-world applications, the decision makers (DMs)’ opinions are often hesitant for decision problems; thus, considering the exact data is difficult. To address the issue, the DMs’ judgments can be expressed as linguistic variables that are converted into the HFSs, con...

In this paper, the structure of SAW has been studied. In previous work in SAW, materials such as lithium niobium, lithium tantalite and gallium nitride were used in the structure of SAW, and thus had a low operating frequency and the highest reported operating frequency was about 4 GHz. In this paper, aluminum nitride and gallium nitride in the SAW structure are used in combination. The electro...
