Abstract

The present study reports the results of an online survey in which we examined gender-specific expectations towards the support mechanisms offered in the decision support systems. The preferred ways of declaring preferences (e.g. using numbers, words, or pictograms) and decision-makers expectations regarding the forms of representing the results by the system (e.g. rankings vs ratings) were analyzed. The relationships between gender and the declarations regarding the support mechanisms were examined using the one-tailed two proportion test and the chi-square test of independence. This study’s main result is significant differences in the preferred form of representation of preference information in decision support mechanisms depending on user gender. The results show that females are more likely to use rating and more willing to declare their preferences using the non-numerical form. Consistent with this finding, females recommend more often the AHP and TOPSIS methods for solving multiple criteria problems than males, while males recommend more often SMART. These results may be used to individualize the decision-making support mechanisms to allow for more reliable preference elicitation.
