Shape transformation of heterogeneous self-organizing system in response to external inluence
Voronin A.E., Yudashkin A.А.
Abstract
A method for synthesis of systems capable to change their forms in responses to external influence is proposed on the basis of a dynamic system of an arbitrary dimension. The model is defined via the set of categorized points on the Euclidean plane and the system dynamics is defined by the potential function, which combines an elastic loop and a self-organizing form with memory. It is shown that the designed system obtains one of the memorized forms under the external influence defined by the set of categorized points, while the subset of system points interconnects with the corresponding subset of external points if their categories matches.

Ontology-based approach to the building of heterogeneous modeling environment
Smirnov S.V.
Abstract
The paper investigates the problem of integration of heterogeneous knowledge in computer-based modeling of complex systems. For solving this problem, it is proposed to use ontology-based approach, which implements in technological terms the common experience of determining the composition and interrelations of main stages of the process of real world modeling and analysis. The paper proposes and analyses the elements of the modeling environment, which act as various pieces of knowledge, all the possible variants of multimodel structures, arising from solving practical tasks, principles of controlling heterogeneous elements of modeling environment, conceptual metamodels for description and interaction of modeling environment elements.
