In this paper we define four types of practical stability of differential inclusions and present properties of inclusion maximal set of these types practical stability. We give the results of investigating the estimation problem of practical stability of differential inclusions right parts. Consideration is given to construction algorithms of inclusion maximal sets of linear differential inclusion stability.

The identification approach to construction of integral models of space-time processes, while distributed observations of their state, is proposed. The influence of initial-boundary effects is taken into account by means of their mean-square modeling. Problems of stability of constructed mathematical models to errors of observations of output signals are investigated.

We consider the important practical and theoretical problem of designing communication network with a minimum total cost to operate under condition of certain its components failing. The model with 0, 1 flow variables contains a number of constraints that is exponential in the number of nodes and we show that its LP-relaxation is NP-complete problem. For some particular cases we prove that the solution of LP-relaxation problem can be obtained by polynomial algorithm. We propose effective algorithms to compute lower and upper bounds for the two connected Steiner problem. For finding this problem solution we employ the branch and bound algorithm and we also report on some computational results.

Consideration is given to possibility of using planar collineation parameters for forming controlling actions in visual control systems of moving objects. Through examples of solving problems of attitude control, translation motion control and stabilization of screw motion of a rigid body, feasibility and effectiveness of proposed control algorithms in terms of the parameters mentioned are illustrated.

Consideration is given to conceptual foundations of Grid system development aimed at the Earth observation data processing. Different approaches to creation of such Grid systems are analyzed and justified, different scientific problems related to development of Grid systems are formulated. A model of Grid system for satellite data processing is proposed. The experience obtained during the development of Grid system for satellite data processing in Space Research Institute NASUâˆ’NSAU is discussed.
