As threshold determination is arduous when using PROMETHEE (Preference Ranking Organization METHod for Enrichment Evaluations) to make decisions, this study proposes a comprehensive PROMETHEE-based group decision support covering the uncertainties of determination, risk preferences, and evaluation itself. To reduce difficulty on it explicitly offers statistical aggregation individuals’ indiffer...

“Black Swans” andgroup decision making have become familiar terms in the relevant fileds. There been many Black Swan events history, such as current covid9 epidemic or failed launch of Challenger space shuttle 1986. In run-up to launch, NASA conducts a conference call.

A decision is often made in a group and decision makers often utilize fuzzy judgments in attempting to reach an optimal solution. In order to deal with the fuzziness of decision makers' judgments in solutions, this paper proposes a fuzzy group decision-making method for multi-objective decision problems. The method allows group members to express their fuzzy preferences for decision objectives,...

As the emergency is always unconventional, sudden and complex, it is necessary to invite experts from different fields to make decisions. However, the decision makers are usually hesitant and cannot get hold of the emergency because of the lack of information and knowledge. In this paper, a group decisionmaking methodology based on intuitionistic fuzzy sets is proposed to solve the emergency gr...

Review on group decision support systems (GDSS) indicates that traditional GDSS are not specifically designed to support mission-critical group decision-making tasks that require group decision-making to be made effectively within short time. In addition, prior studies in the research literature have not considered group decision preference adjustment as a continuous process and neglected its i...
