摘要:Paper is devoted to applying the principles and approaches of fuzzy logic and fuzzy modelling to the solution of applied economic problems in conditions of uncertainty. There are presents the formulation and formalization of the problem, the theoretical foundation of the proposed approach to the solutions, and the practical examples for two tasks of management and economic decisions making. First is construction of investment portfolio. Diversification of investment portfolio as one of the approaches to risk management in the commercial activities in a competitive environment has been consider. Classical approaches to portfolio management are analyzed and practical difficulties of their application in real conditions of market uncertainty are identified. Corresponding methodological approach described and formulation for solution in fuzzy formulation is proposed. An example of numerical calculations in specialized software for operations with fuzzy numbers is given. The obtained results are described and analyzed. Second is development of coordinated assessments of alternative choices for decision making in project management. The choice of alternative products, as part of project management, industrial and commercial solutions, has been described and analyzed. The necessity of the construction of generalized, mutually evaluations of projects, products or services on the basis of opinions of consumers, customers and manufacturers, has been justified. The use of the fuzzy sets for obtain such integrated assessments has been proposed. Mathematical formalized statement of the problem and calculations example are given.
