In this paper, a new approach for the edge detection is presented using fuzzy derivative and evolutionary learning techniques such as bacterial foraging, particle swarm optimization, genetic algorithm and gravitational search algorithm. If-then rules are devised for calculating the derivatives...

Although several books or monographs on multiobjective optimization under uncertainty have been published, there seems to be no book which starts with an introductory chapter of linear programming and is designed to incorporate both fuzziness and randomness into multiobjective programming in a...

This article extends the paper of Dagum C. and Costa M. (“Analysis and Measurement of Poverty. Univariate and Multivariate Approaches and their Policy Implications. A case of Study: Italy”, In Dagum C. and Ferrari G. (eds.), Household Behaviour, Equivalence Scales, Welfare and Poverty,...

Notwithstanding the numerous applications of fuzzy logic in several fields of economics, it is surprising that, to the best of our knowledge, so very few applications have been made in modelling approximations of subjective economic variables, such as confidence, satisfaction or even...

Globalization and technological innovations create investment opportunities for firms worldwide. In fact, while firms pursue foreign direct investment (FDI) opportunities on a global basis, countries compete to attract these flows. Investment decisions by firms depend on complex and distinct...

This paper focuses on the role that social norms play in the selection of equilibrium points seen as social conventions under unforeseen contingencies - that is, their role in the emergence of regularities of behavior which are self-enforcing and effectively adhered to by bounded rational agents...

This paper makes a systematic comparison of four approaches to multidimensional poverty analysis based respectively on the theory of fuzzy sets, information theory, efficiency analysis and axiomatic derivations of poverty indices. The database was the 1995 Israeli Census that provided...
