| Abstract | Urgency of the research. The combination of theory and empirical experience of management with modern cognitive tools determines the necessity to use economic and mathematical modeling managerial decision making in conditions of variability, uncertainty and multidimensionality of the market environment. Target setting. The choice of managerial decision on the set of alternatives is essentially limited to the difficulty of forming a single criterion, which covers different, and in some cases, conflicting requirements. Additional complications are the need to take into account and formalize the uncertainty of both source data and purposes. These lead to the need for use of such models of description of the reality, that allow to process large amounts of data in conditions of the growth of uncertainty. Actual scientific researches and issues analysis. Tools of fuzzy set theory and fuzzy logic are currently an effective means of formalizing uncertainty in different areas of manager's activities: finance, economics, risk management, marketing and many others. These issues are highlighted in the writings of such scholars as K. Kovalchuk, A. Matviychuk, W.-Y. Cheng, L. Lin, M. Wen, Z. Qin, T. Korol and many others. Uninvestigated parts of general matters defining. Issues of description of fuzzy preference relationships based on the aggregate of values of several criteria measured in different scales, and development of scientific and methodological approach to select on this basis the set of most suitable alternatives as a decision currently are not solved enough. The research objective. The main objective of the paper is description of approaches to design fuzzy preference relationships based on the aggregate of values of several criteria measured in different scales, and development of scientific and methodological approach to select on this basis the set of most suitable alternatives as a decision. The statement of basic materials. The procedure of decision making is considered based on the creation of fuzzy preference relationship with membership function, which reflects the degree of confidence in the superiority of one alternative over another. The choice of alternatives carried out from subset of strictly non-dominated alternatives, based on fuzzy preference relationship. Conclusions. Given the availability a lot of criteria of effectiveness, the choice of decision should be based on fuzzy preference relationship. The developed scientific and methodological approaches are aimed to construct fuzzy preference relationship for comparison of alternatives on many criteria simultaneously. It allows to manager to form a set of Pareto-efficient alternatives and choose from them the best as a decision. |
