Some decision-making problems, i.e., multi-criteria decision analysis (MCDA) require taking into account the attitudes of a large number decision-makers and/or respondents. Therefore, an approach to transformation crisp ratings, collected from respondents, in grey interval numbers form based on median scores, is considered this article. In way, simplicity collecting respondents’ using values, b...

Models in Multicriteria Decision Analysis (MCDA) can be analyzed by means of an importance index and an interaction index for every group of criteria. We consider first discrete models in MCDA, without further restriction, which amounts to considering multichoice games, that is, cooperative games with several levels of participation. We propose and axiomatize an interaction index for multichoic...

Bayesian Belief Nets (BBNs) have proven to be an extremely powerful technique for reasoning under uncertainty. We have used them in a range of real applications concerned with predicting properties of critical systems. In most of these applications we are interested in a single attribute of the system such as safety or reliability. Although such BBNs provide important support for decision makin...

The paper shows the contribution that two different multiple criteria decision aiding (MCDA) methods could provide in the field of strategic decisions and urban and territorial planning. In particular, the analytic network process and the dominance-based rough set approach have been considered and discussed in the work with reference to their role in supporting such decision-making processes, t...

Multi-Criteria Decision Analysis (MCDA) is an operations research framework used to support decision-makers in choosing alternatives characterized by multiple conflicting criteria. Over the past years, several MCDA methods have been developed and a significant drawback of using more than one algorithm for given problem potential ranking that they may yield. This work aims at setting first steps...

Intelligent decision system (IDS) is a window-based software package that has been developed on the basis of the evidential reasoning (ER) approach, a recent development in handling hybrid multiple criteria decision analysis (MCDA) problems with uncertainties. In this paper, the evidential reasoning approach will be briefly described first, and its major differences from and the relationships w...

Supplier assessment has become increasingly important to a business and getting a right supplier can bring real competitive advantages, whilst failure in supplier selection can lead to significant operational and financial consequences to a point of jeopardising the survival of the business. In this paper, the application of the Intelligent Decision System (IDS) to supplier assessment for a lar...

This paper presents an application of the integration between Geographical Information Systems (GIS) and Multi-Criteria Decision Analysis (MCDA) to aid spatial decisions. We present a hypothetical case study to illustrate the GIS–MCDA integration: the selection of the best municipal district of Rio de Janeiro State, Brazil, in relation to the quality of urban life. The best municipal district i...

When planning a new development, location decisions have always been a major issue. This paper examines and compares two modelling methods used to inform a healthcare infrastructure location decision. Two Multiple Criteria Decision Analysis (MCDA) models were developed to support the optimisation of this decision-making process, within a National Health Service (NHS) organisation, in the UK. Th...

The fundamental problem underlying all multi-criteria decision analysis (MCDA) problems is that of dominance between any two alternatives: ‘Given two alternatives A and B, each described by a set criteria, is A preferred to B with respect to a set of decision maker (DM) preferences over the criteria?’. Depending on the application in which MCDA is performed, the alternatives may represent strat...
