The core aim of this discipline is to develop tools which will allow us to solve decision problems where potential alternatives are assessed from many, often conflicting points of view formalized by evaluation criteria. Multiple criteria decision analysis tends to evade simple scientific classification. It is perfectly reasonable to see it as one of the most important trends in contemporary computer science, although it should also be said that it is an interdisciplinary field, with IT intersecting with economics, mathematics, cognitive science, psychology and political science. When they are analyzed together, they can help us tackle multiple criteria problems.
