Uncertainty always causes hesitations during decision-making. The uncertainty reduction however is not available through simple operations and easy interpretation. This research solves this problem by proposing an evidential weight based on preferences (EWP). The key technique of EWP is the integration of the roughness measures of an induction rule to reduce noises in doubts. The utilities composed of the derived weight from EWP are empirically used on World Competitiveness Yearbook 2012 to analyze the benchmarking nations. This case study shows European welfare nations (Denmark, Finland, Norway, and Sweden) focus on the long term strategic competitiveness while Asian tiger nations (Singapore, Hong Kong, Korea, and Taiwan) are energetic on short term surviving competitiveness.

The fuzzy measure can highlight important information in analyzing component features, patterns, and trends. However, fuzzy densities and interaction effects are usually unknown or uncertain for implications thus making the fuzzy measure limited in applications. This research proposes an extended fuzzy measure to derive the conditional fuzzy densities from dominance-based rough set approach (DRSA), multiply preferences and the derived densities into utilities, fulfill fuzzy measure identification, and empower the fuzzy measure to aggregate utilities. For illustration, the extended fuzzy measure is applied on World Competitiveness Yearbook 2011 to imply policy-making information for Greece, Italy, Portugal, and Spain. (C) 2012 Elsevier B.V.
