“…Zadeh (1965) introduced the concept of fuzzy set, thus allowing for the elements of a set take different grades of membership, which can be mapped into the interval [0,1], to unlike classical theory of sets, which considers the membership of elements of a set in absolute terms, that is in the set {0,1}. The fuzzy model in discrete time is to adapt the traditional binomial model fuzzy logic; allowing operate and define the ambiguity of the underlying through triangular or trapezoidal fuzzy numbers, particularly in order to estimate movements upward or downward as it points (Muzzioli and Torricelli (2004), Yoshida et al, (2006), Zdnek (2010), Liao and Ho (2010), Wang (2007), Milanesi (2014), andCruz-Aranda et al, (2016).…”
