- Chistov D., Kamaev V., Naboka M. We review and compare the approaches and methodologies of business-process reengineering, and develop the method for telecom business-processes reengineering. The method is based on the technology of ontological engineering. The reference business-processes ontology is created in accordance with a structural framework named “Enhanced Telecom Operations Map”, and also existing business-processes ontology of the telecommunication company is designed. We illustrate the suggested method of business-process reengineering on the example of automated comparison of the reference ontology with the ontology of existing business-processes of a big telecom service provider.

- Yuditskiy S. Changes in configuration of network structures during evolution on a specific time horizon are studied by using the technique of graphodynamics. A set of elementary local graph morphing operations is introduced. A finite-state-machine model of evolution is developed. The model bases on actions that transform network configuration with account of the time factor and impact of the environment.

- Bunich A. The paper overviews the literature on predictive model-based adaptive control systems with identifier (ASI) for discrete objects with parametric and nonparametric uncertainties. It focuses on the relationship between the spectral characteristics of external perturbations and maximum achievable control performance as well as identifier speed. A class of stationary external perturbations with the known spectrum localization is established with the solvable problem of synthesizing the systems of prescribed control precision subject to the criterion of minimum steady-state response variance. The sensitivity of the control system to variations of the spectral composition of disturbances is investigated.

- Zhilina T. We consider stochastic systems modeled by Ito differential equations with Markovian switching, and propose the parametric description (parametrization) of all static output feedback stabilizing controllers. This controllers provide exponential stability in the mean square of the closed-loop system. Using this parametrization we obtain sufficient conditions of stabilization, which allow to develop an LMI-based algorithm for gain matrixes computation of both static and a dynamic regulators. This algorithm is applied to the solution of a stabilization problem of the inverted pendulum on the moving platform under conditions of step-like mass change and random vibration of the platform.

- Furtat I., Tsykunov A. The problem is considered of robust output control of a linear time-varying plant under external and internal uncontrollable disturbances. The relative degree of the plant is unknown and can vary in the course of operation. The problem is solved on the basis of a robust algorithm, which allows compensating the uncertainties with the required accuracy in finite time. The results of computer simulation are provided.

- Zhuchkov R., Pakshin P. For a linear system where a plant and a regulator communicate over a network a stabilization problem is solved in the presence of possible packet dropouts. Dropouts are modeled with a Markovian chain. Cases of state-based and output-based feedback are studied. In both cases LMI technique proved to be efficient.
