Who we are We are an R&D group originating from Russia and Poland. The core of the group is two professors from the Technical University of Czestochowa, Ludmila Dimova and Pavel Sevastianov . Our scientific representative in the USA is Dmitry Sevastianov . It must be emphasized that we are developers oriented on problems, not methods. For example, we found out that fancy genetic algorithms are ineffective for solving portfolio selection optimization problems in a fuzzy setting when compared with other methods for adaptive random search of extremum, which bewilders a lot of young scientists unfamiliar with a history of optimization techniques. However, it does not mean that we do not intend to apply genetic algorithms to solve other problems. Our major scientific directions are modeling, identification, and multicriteria optimization under conditions of different nature in applications for economics, technology, and ecology. They include: Development of interval and fuzzy mathema

If a decision problem is not multiple criteria one, it is not a real-world problem
Foreword This blog is dedicated to problem solving. Every day we choose between multitude of the options, mostly unconsciously, and we base our decisions on a number of criteria that often contradict each other. Every time we do this we solve multiple criteria problem. Our team developed the methodology for solving this kind of a problem, here's my attempt to describe it with extremely non-serious example. I'm going to omit many details for brevity sake, please reach out if you want to learn more! Multiple Criteria Decision Making in a nutshell Case study: Buying a cat Let us consider a problem of cat shopping. With all the breeds and cat personalities out there, it's not a trivial choice. So let's try to approach this consciously. We can come up with some criteria hierarchy, something like this: Fuzziness . Cat's fur can be described by its length Weight Activity . Some pet owners prefer animals not that different from the stuffed toys, others love to play wi
