Lychenko N.M. Decomposition-Coordinated Optimization with Parallel Information Processing for Nonlinear Dynamic Systems (pp. 2-7)
Abstract. Hierarchical algorithms are developed for the optimal control of interconnected nonlinear large-scale dynamic systems. The algorithms synthesis is based on decomposition-coordinated optimization technique with criterion adaptation in the two-level solution structure where the coordinated variables are fixed on the top level, while the independent optimization subproblems are solved on the lower one. For getting computational advantages, it is proposed to apply a concurrent scheme of coordinating variables calculation in the two-level solution structure, whereby the bottom-level optimization tasks are also solved concurrently.
Zhukov V.P. On the Conditions Defining Stability Nature for Some Classes of Nonlinear Dynamic System (pp. 8-10)
Abstract. The paper shows that stability analysis for some classes of nonlinear dynamic systems of any order enables direct Lyapunov function construction based on the second member of the system’s equation. This fact can be used not only for dynamic systems analysis but for their synthesis as well. The conditions determining the stability nature of isolated equilibrium states of autonomous nonlinear dynamic systems of any order are developed; these conditions have clear geometric interpretation. Sufficient and necessary/sufficient conditions for asymptotic stability as well as sufficient conditions for stability and instability are presented.

Abramova N.A. On Risk Problem due to Human Factor in Experimental Methods and Information Technologies (pp. 11-21)
Abstract. The problem of risks due to human factor in the tasks of practical management through expert methods and information technologies is examined as a complex problem comprising the whole lifecycle of such methods and information technologies. Some models of the mental influence of “outward intelligence” on the quality of managerial tasks accomplishment allowing for the risks are presented. Some principles and approaches aimed at confining the role of the identified risk types are proposed.

Tverdokhlebov V.A. Interpolation Techniques in Technical Diagnosis (pp. 28-34)
Abstract. Key issues of technical diagnosis of large-scale and complex systems are discussed. A method for diagnostic models design using interpolation based on partial diagnostic information is expounded. The limitation on fault models application and the capabilities of diagnostic tools are determined by the complex diagnosis objects’ inaccessibility for complete and precise description.
Vedeshenkov V.A. An Approach to Checking Large-Scale Digital Systems with Toroidal Grid-Type Structure (pp. 35-39)
Abstract. An approach to parallel checking of large-scale digital systems with toroidal grid-type structure is presented. The system components are checked in three stages. At the first stage, parallel checking of the components of subsystems parceled out by primary apportionment is executed. At the second (third) stage, parallel subsystems including the connections adjacent to primary subsystem’s nodes fr om the right (from below) are checked. A checking procedure for the components a subsystem with four nodes placed in 2´2 square’s corners is developed and an example of its implementation is included.

Tsyganov V.V., Arzhakov M.V., Bagamaev R.A. Adaptive Ranking Mechanisms (pp. 46-51)
Abstract. The paper discusses the synthesis of progressive adaptive operation mechanisms of a two-level active system whose Center adjusts the parameter of classification decision rule. Based on classification results, the long-sighted system element is ranked and stimulated. Sufficient conditions of the progressiveness of adaptive ranking mechanisms are determined for long- and short-sighted Center.
