In this article considers issues related to increasing efficiency of control for spacecrafts with resource restrictions on the basis of the developed automated information system. Problem domain of control for spacecrafts researched. The role of planning authority in conflict-free use of shared control facilities for spacecrafts with increasing constellation and growing load on facilities shows. Analysis of interaction with subscribers planning authority performed, scheme of interaction constructed. The requirements for a developed automated information system of distribution of control facilities for spacecrafts are formulated on the basis of the analysis of problem domain. The methods of an information exchange planning authority with subscribers are offered, their description and comparative analysis are given. Brief description of special software of developed automated information system is resulted. When using this automated system possibility of occurrence conflict situations is completely eliminated.

We consider the combined algorithm for radial basis neural network parameters selection based on fuzzy immune optimization algorithm. Evolutional construction of antibodies and the use of fuzzy adaptive resonance neural network are used to adapt the neural controller learning algorithm for solving the optimization problem. The possibility of using this kind of neural networks to construct an adaptive network information router and ensuring the integrity of its structure from the targeted destruction is considered.

Information networks are the critical resource of large enterprises, providing high information transmission, processing and receiving speeds. The main objective of the introduction of technology is to create a data center, which can be solved on the basis of the principle of virtualization. The paper presents the results of numerical experiments evaluating the reaction times of server systems based on the principles of the hardware versus server systems based on the principles virtualization. The comparative analysis is given and an approach to physical drives replacement by data storages is suggested.
