QUT researchers develop model to stabilize expert decision rankings

Queensland University of Technology researchers have unveiled a new decision‑making tool designed to improve the reliability of collective judgments in large‑scale projects such as infrastructure development and public‑policy formulation. The model, created by Ph.D. candidates Omid Motamedisedeh and Faranak Zagia of QUT’s School of Architecture and Built Environment, aims to mitigate the volatility that can arise when minor variations in expert opinions produce markedly different outcomes.

By systematically accounting for small discrepancies in individual assessments, the tool offers governments, businesses and other organisations a more consistent framework for evaluating complex proposals. Its developers say the approach addresses a longstanding challenge in group decision‑making, where even slight divergences among experts can lead to divergent conclusions, thereby enhancing confidence in the final decisions made across a range of strategic initiatives.
