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 (...

Purpose: This paper presents an algorithm that can elicitate (infer) all or any combination of ELECTRE Tri-B parameters. For example, a decision-maker maintain the values for indifference, preference, and veto thresholds, our find criteria weights, reference profiles, lambda cutting level. Our approach is inspired by Machine Learning ensemble technique, Random Forest, that, we named as Tree alg...

The aim of this paper is to convince the MultiCriteria Decision Aid (MCDA) and Preference Learning communities to investigate and to contribute in the development of methodologies dedicated to hospital ranking. To do so, we present the French hospital ranking and show how these rankings can be built properly through two existing methods: decision tree and ELECTRE Tri.

Electre Tri is a set of methods designed to sort alternatives evaluated on several criteria into ordered categories. In these methods, are assigned categories by comparing them with reference profiles that represent either the boundary or central elements category. The original Tri-B method uses one limiting profile for separating category from below. A more recent method, Tri-nB, allows use sa...
