Pryima S. Economic and mathematical modelling of pricing in the market conditions.

The dissertation investigates the peculiarities of pricing in market conditions. Existing methods of price prognostication have been analyzed, the spheres of their application and their reliability have been defined. The necessity for and the possibility of the application of the theory of fuzzy logic for the prognostication of economic processes as well as pricing have been proven. The mathematical model of price prognostication with the use of the elements of the theory of fuzzy logic and the theory of reflexivity has been worked out. An expert knowledge base was created on the basis of which equations reflectivity the dependence of the price on the factors represented by fuzzy information were compiled. The possibility of "self-training" of the model was created, which makes possible additions to the information base of the model depending on the economic situation on the market of goods and services.
