The Method of Validating the Structural Parametric Conformity of the Experimental Area to the Functional Communication System 000_2.pdf

The article considers decision making issues aimed at modernizing functional communication systems on the basis of advanced technologies. Conclusion can be drawn on the basis of the analysis. The attention is drawn to the conclusion consisting the fact that the most promising direction in this sphere is using experimental areas for validating system engineering solution in case of constructing and modernizing communication systems. However, experimental areas should have a similarity measure to the original (a functional communication network). Using a graph model of a communication system and the method of graph sparsification allowing to obtain samples(less dimensionality graphs) that are isomorphic with respect to the initial graph would be appropriate. The article reviews the algorithm of forming a graph model of an experimental area with the use of sparsification. It is shown that in the result of the initial graph sparsification, a sharpen sequence of samples (subgraphs) demonstrating the structure of a functional communication system on the corresponding stage of the modernization (also in the experimental area) was obtained. The authors consider the structure of the sequence samples for the specified number of modernization stages of the functional communication system got through the initial graph sparsification. The statement of the problem of forming the experimental area in the basis of structural parametric construction of the functional communication system is given. The analytical apparatus and the algorithm are demonstrated. The solutions of the application field extension for structuring the communication system for its sequent modernizing stage. The analytical correspondence between the target function and conditions of the task solution is demonstrated. As the result, the method of sequent transformation of the functional system structure into the experimental area with providing its structural parametric similarity to the original in the form of a set of corresponding procedures is presented. The original refers to the isomorphic communication system, which elements, functions, properties, and relations that are of importance to the system can be put into one-to-one correspondence.

Navigation Structure-building of an Electronic Archive for Technical Documentation on the Basis of Ontological Models 33_9.pdf

The article contains a description of a formation process of an electronic technical documentation archive navigation structure on the basis of ontological models. A preliminary document indexing is made in order to receive ontological concepts. The domain ontology is represented in the form of RDF-triples "object-subject-predicate". The electronic technical documentation archive structuring and the formation of its navigation structure are executed in order to find a set of the technical documentation semantically similar to a certain document which is appealing to the designer.
