GROMOV, YU.V. MININ, S.A. KOPYLOV, N.A. KAREVA A model of the fuzzy optimization problem of the distribution of elements in a network information system with a tree-tree topology operating under conditions of uncertainty is formulated. The resulting optimization problem is characterized by the presence of fuzzy parameters, presented in the form of numbers of L-R type. To solve the formulated fuzzy optimization problem, a procedural model is developed based on the solutions of the optimization problem for the parameters corresponding to the left fuzzy intervals and the right intervals, respectively. Keywords: network information system, element, node, uncertainty, fuzzy number. DOI: 10.25791/pribor.07.2020.1193 Pp. 47-54.
