We propose two straightforward methods for deriving the priority vector associated with a fuzzy preference relation. Then, using transformations between multiplicative preference relations and fuzzy preference relations, we study the relationships between the priority vectors associated with...

In this paper we show that the widely used normalization constraint SUM(i=1,n) wi = 1 does not apply to the priority vectors associated with reciprocal relations, whenever additive transitivity is involved. We show that misleading applications of this type of normalization may lead to...

In this paper we propose an approach to Social Network Analysis (SNA) based on fuzzy m-ary adjacency relations. In particular, we show that the dimension of the analysis can naturally be increased and interesting results can be derived. Therefore, fuzzy m-ary adjacency relations can be computed...

In this paper we present an overview of the soft consensus model in group decision making and we investigate the dynamical patterns generated by the fundamental pairwise preference interactions on which the model is based. The dynamical mechanism of the soft consensus model is driven by the...

The use of cointegration tests has become very popular in the empirical analysis of the tourism-led growth hypothesis (TLGH). It was first introduced in the tourism economics literature by Balaguer and Cantavella-Jordà (2002) and then popularized by many researches which tried to assess the...

In the context of Social Welfare and Choquet integration, we briefly review the classical Gini inequality index for populations of n ≥ 2 individuals, including the associated Lorenz area formula, plus the k-additivity framework for Choquet integration introduced by Grabisch, particularly...

Il lavoro studia la dinamica della produttività di un campione di imprese manifatturiere italiane nel periodo 1995-2006. Il calcolo della produttività è basato sull’indice di Malmquist, calcolato impiegando tecniche non parametriche. La scomposizione dell’indice...

This paper reviews a class of multifractal models obtained via products of exponential Ornstein-Uhlenbeck processes driven by L«evy motion. Given a self-decomposable distribution, conditions for constructiong multifractal scenarios and general formulas for their Renyi functions are provided....

We consider the classical inequality measures due to Gini, Bonferroni, and De Vergottini and we present a brief review of the three inequality indices and the associated welfare functions, in the correspondence scheme introduced by Blackorby and Donaldson, and Weymark. The three classical...

Productive efficiency in hotels varies greatly. Based on a large dataset on the hotel industry in an Italian region, a two-stage approach was used, first to distinguish the component of inefficiency arising from external factors, linked to destination, and then to isolate the role that...
