Abstract

The traditional logic (crisp) is based on the dichotomy of true and false, what is not true is false and what is not false is true. Half term does not exist. However, the real world presents some situations where the answers true and false are not enough to represent the reality. Using this idea, it was applied, in this paper, the logics crisp and fuzzy to a problem of choose of place for the implantation of a gauge station in a watershed. COPPETEC-COSENZA model for crisp logic and operation with triangular numbers in electronic spread sheet (fuzzy) were adopted. The same results had been presented with regard to the adequateness to the implantation of the gauge station.
