Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Solution of the problem of searchof maximin levels of users demandin network information systemin the conditions of uncertainty V.N. OSIN,A.Y. GROMOVA,V.V. RODIN,M.N. KRASNYANSKY 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. Keywords: Algorithm FPTAS, LR-numbers.
