Applying simulated annealing to design compact zones

E.A. Rincón García, J. Ramírez Rodríguez, P. Lara Velázquez. Universidad Autónoma Metropolitana-Azcapotzalco

M.Á Gutiérrez Andrade, S.G. de-los-Cobos-Silva. Universidad Autónoma Metropolitana-Iztapalapa

Compactness is an important principle in redistricting process, and there are different measures to quantify this property in electoral zones. However, these measures are unsatisfactory, since they can be unable to favor the design of compact zones in enough complicated problems. In this paper, we propose that a compactness measure…

Uncertain induced generalized aggregation operators and its application in the theory of expertons

José M. Merigó, Anna M. Gil Lafuente, Luciano Barcellos. University of Barcelona

We present a new approach that unifies the induced generalized ordered weighted averaging (IGOWA) operator with the weighted average (WA) when the available information is uncertain and can be assessed with interval numbers. We call it the uncertain induced generalized ordered weighted averaging – weighted averaging (UIGOWAWA) operator. The main…

The attractiveness of countries for FDI. a Fuzzy approach

Marina Murata. University of Modena and Reggio Emilia, RECent: c/o Department of Economics, University of Modena and Reggio Emilia

Tommaso Pirotti. University of Modena and Reggio Emilia

This paper presents a new method for measuring the attractiveness of countries for FDI. A ranking is built using a fuzzy expert system whereby the function producing the final evaluation is not necessarily linear and the weights of the variables, usually defined numerically, are replaced by linguistic rules. More precisely,…
