Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Analytical and procedural models of the analysis of functioning of network information system at satisfaction of external demands in the conditions of uncertainty YU.YU. GROMOV, V.N. OSIN, Y.V. MININ, O.G. IVANOVA In this paper we consider a problem finding of distribution of flows in the network information system, in the best way using resources of a network in the conditions of uncertainty. For its solution it is offered to use approximate algorithm FPTAS of search of a maximum concurrent flow usage of LR-numbers for the uncertainty registration. Key words: Network information system, Algorithm FPTAS, fuzzy LR-numbers. E-mail: osin_w@mail.ru. Pp. 12-16
