Article
The representation of social phenomena has been associated with substantial conceptual and operational difficulties. Social phenomena have a complex multidimensional nature that leads to different conceptualizations and measurements. This problem makes it difficult to choose the sub-indicators to be considered in the composite indicator of the phen...

Composite Indicators are one-dimensional measurements that simplify the interpretation of multidimensional phenomena that facilitate public policies' elaboration. The literature on composite indicators is abundant, diversified, and inserted in practically all knowledge areas. Part of this literature aims to reduce uncertainties that propagate throu...

Full-text available
The aggregation of variables is one of the most critical procedures in the building of Composite Indicators. Most of the debate is about the issue of compensation between variables with poor and above-average performance. Researchers understand that non-compensatory aggregation is more appropriate than compensatory aggregation for measuring multidi...

Intra-urban inequality is not strictly defined and therefore cannot be measured accurately. The literature shows that the measurement of inequality varies depending on the judgment of the experts and that this judgment can be realized in several ways. Taking this into account, the capabilities created using fuzzy set theory and consensus schemes ca...

Composite indicators are almost always determined by methods that aggregate a reasonable number of manifest variables that can be weighted-or not-as new synthesis variables. A problem arises when these aggregations and weightings do not capture the possible effects that the various underlying dimensions of the phenomenon have on each other, and con...

Internet network design specialists are looking for technologies and strategies to deliver network service under increased demand conditions. The choice of strategies is based on applying optimization and decision-making methods to select the most appropriate cable network design considering criteria established by the problem definition. However,...
