Pension trustees make surrogate decisions on behalf of scheme members. However, prior research has not explored how this might affect pension adequacy. Our results show that when setting targets for replacement income, project their own preferences instead reflecting member preferences. Furthermore, projection was more pronounced with lower financial literacy. Trustees choose significantly high...

Performance evaluation enables decision makers (DMs) to have a better view about the weaknesses and strengths of leading units improve efficiencies as crucial goal. Data envelopment analysis (DEA) is most popular technique measure performance efficiency making (DMUs). However, conventional DEA unable consider uncertainty input output data in evaluations. In this study, order address data, robus...

Decision making is an important part of human life. A decision can be made by the idea of an individual or a group. Groups are seen as superior to individuals as decision making entities. In fact, groups bring more diverse sets of information, perspectives, and knowledge to make a decision. A type of group decision making is related to multiple criteria and multiple constraint levels linear pro...

The assessment of the implementation of green chemistry principles in the syntheses of nanomaterials is a complex decision-making problem that necessitates the integration of several evaluation criteria. Multiple Criteria Decision Aiding (MCDA) provides support for such a challenge. One of its methods – Dominance-based Rough Set Approach (DRSA) – was used in this research to develop a model for...

Owing to the uncertainty and vagueness of practical decision-making problems, it is more convenient for decision-makers (DMs) express evaluation information with fuzzy preference relations (FPRs) than precise numerical values. As two important issues in process FPRs, improving consistency acquiring priority weights are worth further studying. In this paper, we first provide an approach construc...
