S.L. Starchak
The questions of security of spacecraft from intentional exposure. Analysis of international space law and the UN Charter allows the hypothesis of the possibility of solving the problem of "gray" area of international space law. A model of the influence of space systems in terms of balance of the opposing sides. Shows a generalized mechanism of the effect of space systems on the efficiency of the armed struggle. Proposed concept and definition of acceptable limits impact on space systems.

V.A. Kuznecov
We propose a methodological apparatus that formalize the dependence of the efficiency of the fighting on the composition and characteristics of space systems provide. We introduce the notion of a generalized consumer. The model includes a generalized consumer decomposition timeline functioning of precision weapons in separate stages, and establishes the dependence of its efficiency of execution probabilities of individual stages. Perform steps made dependent on the characteristics of information management, with the participation of space systems.

77-30569/242645 Database constructor on basis of entities and their properties with possibility of normalization
# 01, January 2012
MVinogradova, EIgushev
The authors consider principles of creating database constructors which have a convenient graphical user interface and a universal normalization tool. The constructor allows operating not only with attributes and functional dependences, but also with entities which unite attributes. The database structure normalization algorithm is based on Ullman algorithm which additionally carries out analysis of keys entry into determinants and dependant parts of functional dependences, and which also reveals entities unambiguously determining one another. The algorithm is adapted to the presence - in the structure - of not only attributes but also entities that unite attributes.
77-30569/242870 Uniqueness property of algorithm development when designing multiaspect information systems
# 11, November 2011
MVinogradova
Class of multiaspect information systems was defined as class of organized control systems, closely-coupled with data and functions. The problem of decreasing the multiaspect system development cost was set. Standard methods of decomposition and out-of-the-box solutions were recognized ineffective. Aspect approach to designing of information system based on strict formalization of design process was proposed. Uniqueness property of algorithm development was formulated; it allowed to achieve the uniqueness of problem description when outlining it. Requirements that allowed to achieve the uniqueness were specified. Lemma that the uniqueness property of algorithm development was achieved with the fulfillment of listed requirements   was proved.
77-30569/242041 Synthesis of parameterized dynamic conceptual model of diverse systems special weapons
# 10, October 2011
S.V. Voronin
The paper proposed a universal basis for the development of mathematical models of weapons systems, regardless of their purpose and scope. Universality is ensured by the use of inductive-deductive approach to the synthesis of a conceptual model of a system consisting of information, managing and firing components. Dynamic parameterization defines static and dynamic properties of the system and its elements, the order and dynamics of the interaction. As part of the conceptual model achieved a complete description of the theoretically possible set of options for building the system.

77-30569/239406 Evaluation the effectiveness of ordered set operations
# 10, October 2011
V.A. Ovchinnikov, G.S. Ivanova
The efficiency of using ordered set operations is considered by example of partitioning a complex system structure into subsystems. The article considers a formal definition of this problem as separation of the hypergraph vertex set into disjoint subsets. The article describes the main design routines of computer scheme partitioning by sequential algorithm. The partitioning process was fulfilled by using unordered and ordered set operations. The computation complexity assessment of both member functions was fulfilled. The efficiency of using ordered set operations may be proportional to the quantity of network elements.
