Aerospace Instrument-Making Annotation << Back Method of the substantiation of structure of an information subsystem of a providing functional organizational-engineering system. L.E. Mistrov The method of the substantiation of structure of an information subsystem of a control system of a providing functional organizational-engineering system is offered on the basis of a solution of an integer problem of optimization interleaves of connections of integration between a different sort by sources of information in coverage boundaries of a system. The method is realized on the basis of a combinatorial method of a solution of discrete problems of optimization, method of construction of a sequence of solutions and approximated method of sequential assigning of units of a resource.
