Features of systems of network-centric control and problems of system complexity of their implementation on the heterogeneous computer networks are analyzed. The reasons are established and ways of elimination of combinatorial complexity of tasks of the functional integration of heterogeneous resources are shown. Approach to formation uniform, seamlessly programmable and cyber safe algorithmic space of network-centric control on the basis of new element basis in the form of the single-crystal networked computer with nonmicroprocessor architecture is provided

This paper studies the properties of resource networks with sink vertices called absorbing resource networks. In the presence of at least two sinks, the resource distribution in the limit state depends on the initial state of the network. We formulate two control problems in such networks. Sinks are treated as goal vertices. Control vertices represent some subset of vertices in the transition component.

The dynamic models of informational control in social networks were considered. The problems of analysis and design of the optimal controls were posed and examined.

Abstract—Mathematical modeling of the population dynamics is performed for states of a three-level system (atom) with a V-type configuration transforming a light pulse. It is assumed that the excited eigenstates of the atom are degenerate and coupled by coherent interaction, one of the states being radiating (radiative), while the other state is nonradiating (“dark”). The population dynamics of atomic states is described on the basis of numerical solutions of equations for the matrix elements of the density operator. The dependence of the effi- ciency of population of the atomic dark state from the values of the parameters of an irradiation pulse and from the ratio of the period of population oscillations of excited atomic states (caused by their coherent interaction) to the lifetime of the atomic radiating state is determined. Typical examples of the time dependence of the pop- ulation of states of the atom considered are presented for the cases of irradiation by a short (as compared to the lifetime of the radiating state) sinusoidal light pulse and by a long rectangular light pulse with the resonance carrier frequency.

To analyze and evaluate the uncertainty of an innovation project, it is considered as a complex engineering system in which the degree of satisfying the desired performance characteristics of a product is modeled by the cumulative probability of its technical success. It is shown that this probability is distributed by the Weibull law. This probability of non-failure execution of a project activity is an index of the activity reliability; it allows one to obtain a lower bound of guaranteed reliability of the whole project. The two-objective problem (time and cost) is represented as the minimization problem by two successive objective functions; this implements the lexicographic method of ordering the solution of one-objective problems by the importance of the objectives in vector-valued optimization. For one-objective convex problems in which the initial data are known inexactly, a regularized solution method is used. The proposed model and method for solving the two-objective problem are used for the development of a computerized integrated system for innovation project planning.
