Many real life problems require simultaneous optimisation of more than one objective function. For example, a portfolio optimisation problem consists of two conflicting objectives: maximise expected portfolio return and minimise the risk. A trade-off between the criteria is needed to ensure a satisfactory design of stochastic systems.

Our research on MCDA includes the use of restricted trade-offs, which are common in environmental problems. A DSS has been designed and implemented for the International Atomic Energy Agency to assist decisions in the power sector.

Another focus is on the integration of partial user preferences in the optimization.
