New model identifies expert consensus to keep complex decision rankings stable

A new decision-making tool developed by Queensland University of Technology researchers could help governments, businesses and organizations make more reliable decisions for such projects as major infrastructure and public policy development. Developed by Ph.D. researchers Omid Motamedisedeh and Faranak Zagia from the QUT School of Architecture and Built Environment, the model addresses a major challenge in group decision-making: Small differences in expert judgments can sometimes lead to dramatically different outcomes.
