Aerospace Instrument-Making Annotation << Back POSSIBLE APPROACH TO THE FORMATION OF MULTIPLICATIVE GENERALIZED CRITERION OF THE EFFICIENCY OF THE AIRCRAFT V.F. Vititin, M.Y. Kalyagin, V.S. Safronov The paper considers one of the possible options for the formation of a global criterion for evaluating the effi ciency of an aircraft. It is shown that a widely used criterion for estimating the effectiveness of an aircraft constructed on the basis of convolution of partial probabilistic criteria has significant shortcomings that can lead to erroneous solutions. The proposed approach to constructing a global criterion on the basis of t-norms and matching functions avoids a number of shortcomings in the criterion for multiplicative convolution of probabilities. Comparative results of constructing a generalized multiplicative criterion obtained on the basis of the proposed approach and a criterion obtained on the basis of convolution of partial probabilistic criteria are presented. Key words: function of correspondence, triangular norm, reliability, effi ciency, aircraft. Contacts: E-mail: v.s.safronov@mail.ru Pp. 20-27.
