2022-8: Multiple criteria, aggregation and multiobjective optimisation

Date: Wednesday 31 August
Time: 1.00pm – 2.00pm

Speaker: Professor Gleb Beliakov

Title: Multiple criteria, aggregation and multiobjective optimisation

Abstract: I will present a few industry-driven problems which require optimal solutions with respect to different criteria. Then I will formulate the corresponding multiobjective optimisation problems and discuss various concepts and challenges of this domain. I will then talk about aggregating objectives into fewer or just one, as an attempt to reduce dimensionality or solve single-objective traditional problems. We’ll examine various ways to aggregate the objectives, which go beyond the traditional weighted means, and outline their features. I will end with multiple criteria decision making problems and the role of aggregation functions.
