  • Model of management of a polystructural system on the basis of estimation and choice of alternatives by pairwise comparisons

    When managing complex systems, for example, an industrial enterprise, an organization, a socio-economic system, etc., it is necessary to take into account the fact that they can be considered as polystructural systems, i.e. as a set of heterogeneous systems, interconnected. A poly-structural system is understood to mean a variety of different components, differing in physical properties, functional purpose, complexity of the internal structure, representing a single whole. The article deals with the management of a polystructural system based on the preparation of management decision making by experts who can evaluate an alternative from the standpoint of a specialist of several elements of a polystructural system. To develop methods for determining and selecting an informed management solution, a polystructural system is considered from the standpoint of system theory and system analysis. A mathematical model is developed, which is the basis for creating information and algorithmic support for the management of the polystructural system.

    Keywords: management of a polystructural system, the choice of an administrative decision, indicators, a problem situation, the method of analyzing hierarchies, reducing the complexity of the examination

  • To questions of construction of integrated operators with осциллирующими in factors in space L2(Bn)

    Article is devoted multidimensional integrated operators with homogeneous kernels and oscillating in factors of a special kind. The operators representing the sum of the composed are studied: the initial integrated operator with a homogeneous kernel, the operator with осциллирующим in factor and a homogeneous kernel. For the given operators the concept of a symbol, of which terms is defined the criterion neterovosti and the formula of calculation of an index is received. The task in view decision is based on a reduction of the multidimensional integrated equation to infinite diagonal system of the one-dimensional equations.
