Problem of allowed path construction for a graph is considered. It is shown that in the Euler graph is possible to build a valid Euler tour and in arbitrary chosen graph it’s possible to build a valid network. The algorithms presented are complimented by examples using software developed by the authors.

This article describes an approach to requirements for integrated information system systematization. The approach proposed is the framework that can be used for the technical requirements formalization aiming to classification and definition of the relationship between the different types of requirements.

A problem of threshold values selection for pattern recognition of compact sets with one sample per object using algorithms for calculating estimates is considered. We study an option to extend the set of samples by ad — hoc set of reference samples. Experimental results and sample set generation options are provided.

Indoor local agent positioning problem is considered. Self-organization method for agents while obtaining information of the external environment parameters was synthesized. The methods for constructing a global agents’ coordinate system was created along with methods for local coordinate system computation. Comparative analysis with the wide spread mutual commitment method showed the considerable advantage of the hybrid approach while dealing with a large group of agents with high-speed data communication hardware.
