The former method starts by numerically estimating the adequacy and the inadequacy (with respect to the initial data) ofeach statement "the alternative i appears in on aggregate hierarchy on the j-th place* and constructs a preorder which maximizes the ratio of total sum of adequacy values by the total sum of inadequacy values for the associated hierarchy. The latter method involves usual conco...

This paper presents a new fuzzy multicriteria classi®cation method, called PROAFTN, for assigning alternatives to prede®ned categories. This method belongs to the class of supervised learning algorithms and enables to determine the fuzzy indi€erence relations by generalising the indices (concordance and discordance) used in the ELECTRE III method. Then, it assigns the fuzzy belonging degree of ...

This paper describes an automated tool that allows the analyst to systematically vary key parameters of the ELECTRE III multicriteria decision-making tool, thereby facilitating sensitivity analyses of the results. We also demonstrate how the sensitivity analyses can be presented by means of an intuitive graphical depiction of shifts in the rankings of alternatives that can be readily interprete...

As the mobile technologies and services are in constant evolution, many speculate on whether or not mobile payments will be a killer application for mobile commerce. To have a better understanding of the market, there is a need to analyze not only the technology but also the different actors that are involved. For this purpose, we propose to conduct two disruption analyses to draw the disruptiv...

This article proposes a principled approach to multicriteria decision making (MCDM) where the worth of decisions along attributes is not supposed to be quantified, as in multiattribute utility theory, or even measured on a unique scale. This approach actually generalizes additive concordance rules a la Electre and is rigorously justified in an axiomatic way by representation theorems. We indeed...

Multi criteria decision making (MCDM) methods like analytic hierarchy process, ELECTRE and multi-attribute utility theory are critically studied. They have irregularities in terms of the reliability of ranking of the best alternatives. The Routing Decision Support (RDS) algorithm is trying to improve some of their deficiencies. This paper gives a mathematical verification that the RDS algorithm...

Background: Low-cost carrier (LCC) is a popular air transportation service as it offers affordable fares. Many airlines have adopted the LCC system because they need to adapt changes in airline industry. The competition tight. Despite low cost, consumers demand quality services. Therefore, find their competitive edge. Objective: This study aims determine best-performing airlines, criteria, and ...

The present research aims to propose a Supplier Selection Model that creates collaborative relationships in Supply Chains, so suppliers can be previously categorized into the cooperation, coordination and collaboration levels. Applied, quantitative, exploratory descriptive methods were used. A bibliographical research, questionnaire, quantitative modeling adopted as methodological procedures. m...
