Fuzzy Interval-Valued Numbers in the Evaluation of Uncertain Parameters of the Investment Projects

Management of real investments is one of the key activities of modern enterprises. Real investments, especially those related to the formation of new capital (new companies, new production facilities), are associated with various types of uncertainty. This paper proposes to use the framework of fuzzy interval-valued numbers to model the uncertain parameters of the investment project and calculate the net present value. Fuzzy interval-valued numbers, which are often interpreted as fuzzy numbers of the second type (order) or super-fuzzy numbers, make it possible to model not only the value uncertainty on the base axis (carrier) of a certain parameter, but also the uncertainty associated with the value of the membership function. The paper proposes an algorithm for estimating the net present value of a project based on operations with fuzzy interval-valued numbers.
