BARRIENTOS SEBORGA, Carmen Inés. Multivalued logic in the evaluation of investment projects. Investigación y Negocios [online]. 2023, vol.16, n.27, pp.51-61. ISSN 2521-2737. https://doi.org/10.38147/invneg.v16i27.194.
Classical logic starts from the postulate that an element can only be in one or the other of two mutually exclusive states (“X” or “not X”), so that the assignment of the element to a state is total, for example: 0 or 1; Yes or no; True or false. This limitation is overcome in multi-valued logic, admitting not only “X” and “not X” as alternatives, but also the infinite possibilities found in between.
In situations where the information with which you work is un- certain, multivalued logic allows you to interpret the facts with greater precision. In this context, considering that the results of an investment project in the future are uncertain, this paper in- tends to use multivalued logic in the before evaluation of investment projects, in such a way that uncertainty is considered. that every project is associated with. For this, a mathematical model will be elaborated that considers the Fuzzy Triangular Numbers (NBT’s) in the calculation of the Net Present Value, therefore, the treatment corresponds to the quantitative-experimental approach.
