two aspects of interdependence
problems of system identification under uncertainty
suitability of reduced models for control synthesis
potential of refinement of structure and model parameters
iterative identification
feedback.
We consider two aspects of interdependence of problems of system identification under uncertainty, as well as control on the basis of mathematical models obtained by approximate experimental data. The first one deals with suitability of reduced models for control synthesis, and the second one is connected with potential of refinement of structure and model parameters on iterative identification of the system already closed by feedback.

ultra weak boundary value problem
Helmholtz equation.
Discretization of ultra weak boundary value problem for the Helmholtz equation, under the condition that the ultrasound source is described by Dirac delta function, is considered. To reduce the computational complexity, on the basis of the nature of processes, we use the approximation functions, which describe the wave processes.

multicriteria optimization problem
fractionally linear objective function
vector optimization on combinatorial sets
reducing the initial problem to a series of scalar (one-criterion) problems.
We consider a multicriteria optimization problem with fractionally linear functions of the criteria, which is defined on the combinatorial set of arrangements. The approach to its solution is proposed and justified, properties of the region of feasibility of the problem and their use while construction of the method are investigated. The analysis of the results of the performed computing experiment demonstrates the effectiveness of the proposed approach.
