An algorithm to elicitate ELECTRE II, III and IV parameters

Autor: Carla Martins Floriano, Brunno e Souza Rodrigues, Marcos Costa Roboredo, Valdecy Pereira

Publikováno v: Data Technologies and Applications. 55:82-96

PurposeThis paper presents an algorithm that can elicitate all or any combination of parameters for the ELECTRE II, III or IV, methods. The algorithm takes some steps of a machine learning ensemble technique, the random forest, and for that, the auth

An exact approach for the r-interdiction median problem with fortification

Autor: Marcos Costa Roboredo, Luiz Aizemberg, Artur Alves Pessoa

Publikováno v: RAIRO - Operations Research. 53:505-516

We study the r-interdiction median problem with fortification (RIMF), which considers demand points that are served by facilities. If a facility is interdicted, it can not serve any demand point, increasing the total system cost. To avoid an interdic

Electre Tree A Machine Learning Approach to Infer Electre Tri B Parameters

Autor: Valdecy Pereira, Gabriela Montenegro Montenegro de Barros, Marcos Costa Roboredo

Purpose: This paper presents an algorithm that can elicitate (infer) all or any combination of ELECTRE Tri-B parameters. For example, a decision-maker can maintain the values for indifference, preference, and veto thresholds, and our algorithm can fi

A branch-and-cut algorithm for the multiple allocation r-hub interdiction median problem with fortification

Autor: Marcos Costa Roboredo, Hugo Quadros, Artur Alves Pessoa

Publikováno v: Expert Systems with Applications. 110:311-322

Hubs are special facilities widely found in distribution systems acting mainly as transshipment and switching points, being used to concentrate and consolidate flows. Every hub is subjected to a disruption of its functionality, called interdiction, t

A DEA model to evaluate Brazilian container terminals

Autor: Marcos Costa Roboredo, Lidia Angulo Meza, Eduardo Fagundes Costa

Publikováno v: RAIRO - Operations Research. 52:743-754

This study aims to evaluate the main Brazilian port terminals specialized in the operation of containers between the years 2010 and 2014. Therefore, it was applied Data Envelopment Analysis (DEA) and some of its complementary models, represented by t

An exact approach for the r-interdiction covering problem with fortification

Autor: Marcos Costa Roboredo, Artur Alves Pessoa, Luiz Aizemberg

Publikováno v: Central European Journal of Operations Research. 27:111-131

In this paper we treat the r-interdiction covering problem with fortification (RICF). The environment of this problem is composed of a set of customers J and a set of facilities I. For each customer j, there is set of facilities containing the facili
