Epistemic analysis of methods using elementary triangular fuzzy numbers with associated indicators

The current scientific research is characterized by an advanced specialization, emphasis on increasing fragmentation of research topics. In these conditions, the most results have a low degree of comparability and complexity of the subject studied is drastically reduced. In this paper we propose an epistemic approach of the main methodologies for the quantification using triangular fuzzy numbers, emphasizing the possibilities of knowing the limits and influences entailed by the use of current techniques and the theoretical contingencies. By using indicators of centers of weight associated to fuzzy number, we try to bring into question, through a multidisciplinary approach, the new possibilities of develop and complete the portfolio of instruments which can be used for decision-making
