The main objective of this work is to build an evidence feeling that the use of betaindicators inside of a system of important information elevates the efficiency of the taking-decision mode. It is considered as a type indicator that has the characteristics of a vector and it establish acting strips. The beta-indicators, for a variable, start from optimist, more-probable and pessimist values and define the beta-distribution that adapts to values facilitating the define areas of normal and abnormal acting leaving of probabilistic beta distribution of the considered variable. The validation of the model in analysis was made on the technical judgment emitted by specialists. For the calculation of specialists concordance was used the proposition (Double Notation Paraconsistent Logic) with the modifications for the context of technical judgment.
