Synthesis of Ukraine Budget Revenues Model in Conditions of Shadow Economy using Modified Method of Structural Identification

Models for prediction of Ukraine budget revenues under conditions of shadow economy are built in the work. To build these models, known structural identification method used and modified one has been used. The necessity of modification of the known method consists in the following fact: while identifying the neighborhood of known nectar sources, the deterministic approach is used. The paper proposes to unify the concept of nectar source neighborhood for each of them regardless of its value (quality) by using a modified operator of nectar source generation. The results of comparative analysis showed that the use of modified method of structural identification is at least 14% more effective.
