Abstract
La lógica clásica parte del postulado de que un elemento solo puede estar en uno u otro de dos estados mutuamente excluyentes ("X" o "no X") de manera que la asignación del elemento a un estado es total, por ejemplo: 0 o 1; Si o No; Verdadero o Falso. Esta limitación queda superada en la lógica multivaluada, admitiendo no solo el "X" y el "no X" como alternativas, sino las infinitas posibilidades que en el medio se encuentran. En situaciones donde la información con la que se trabaja es in- cierta, la lógica multivaluada permite interpretar los hechos con mayor precisión. En ese contexto, considerando que los resulta- dos de un proyecto de inversión en el futuro son inciertos, con el presente trabajo se pretende emplear la lógica multivaluada en la evaluación ex ante de los proyectos de inversión, de tal manera que se llegue a considerar la incertidumbre que todo proyecto tiene asociado. Para ello, se elaborará un modelo matemático que considere a los Números Borrosos Triangulares (NBT´s) en el cálculo del Valor Actual Neto, por tanto, el tratamiento corresponde al enfoque cuantitativo- experimental.
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.
