Abstract: The efficiency of the decision making process and the proper management of the situations of uncertainty require the intensification of the interdisciplinary theoretical approaches and the adaptation of methods from related fields. Uncertainty is no longer treated only as a factor that generates difficulties, but becomes an instrument in the management strategies, an opportunity for development. At the same time, the advances in the fuzzy theory allow the outline of new horizons in approaching the theoretical concepts in management, the development of existing methods and the outline of new lines of theoretical analysis. The use of fuzzy numbers with associated indicators is becoming increasingly important in developing decision making methods. In this context, the present article proposes the development of triangular fuzzy numbers with variable associated indicators and based upon specific elementary operations. Thus, a new theoretical direction for approaching the decision making processes and specific instruments is proposed, which is much closer to the practical mode, depending upon an index of uncertainty adsorption and management.
