The paper presents an extended version of the algorithm of numerical simulation of multi-link Markov chain with stationary transition probabilities. The results of the algorithm using for assessing the adequacy of speech signals parameterization with Markov chains of higher orders are obtained and analyzed.

Capability potentiality analytic form of discrete channel composing continuous channel, modulator and demodulator. Continuous channel nature describes likelihood function, opera-tions of modulation and demodulation identify by output demodulator signal stochastic prop-erties.

The article is devoted to an experimental research of models of distributed call centre on the basis of simulation modeling. Simulation results are presented that show the quality of service calls in distributed call centers in different variants of awareness about the state of individual call centers, members of the distributed call centers.

In work use a physical model of nonlinear dispersive link in a chain of cascaded linear and nonlinear inertial freewheeling two-ports. The possibility of such a model, the mathematical description of the functional matrix whose elements are functions of the input signals. On the basis of functional matrix constructed tensor model nonlinear dispersive channel in the form of multi-dimensional curved surface. The analysis of the properties of the model by means of vector analysis.Describes a method for optimizing signals using tensor derivative of the vector field outputs nonlinear dispersive channel.

The model of functioning of the router was developed and the influence of faults of com-munication canals on its reliability by the factor of serviceable condition probability was esti-mated. The metrics of reliability of the network, which applies different routing protocols, in case of number of communication canals with limited reliability and the intensity of their faults, were researched.

This article discusses an algorithm designed for Wi-Fi networks for monitoring parameters of distributed objects.

The methodic of quality estimating for telecommunication products delivery for telecom-munication operator. Its based on calculation all services, delivered into service layer agree-ment, and make apriority estimation for required resources with confidence interval. Interval summary value of resource-intensiveness, confidence interval and service layer agreement make required quality estimation.

The article is devoted to the features of the organizational, elemental and information structure, which are necessary to be considered by forming the CCTV systems and designing of systems. Recommendations on optimal choice of the system in consideration of features of functional requirements to the CCTV systems in multiplexes and cineplexes are formulated.

The article is about considering memory while calculating acceptance tolerance of controlled parameters for automated control of dynamic object condition.

Some variants of concept «ERP-system» are considered in this article, it is described the historical dynamics of development of complex information systems of planning and man-agement of financial and economy enterprise activity, the main problems of ERP-system’s implementation and prerequisites of implementation with minimum efficiency in Russian business are analyzed in this article.
