Assessment of the continuity of information interaction and communication in monitoring systems with a dynamic structure

Formulation of the problem. Modern spatially distributed monitoring systems with mobile information tools (of various bases) provide for the collection and primary analysis of intense data streams. But at the same time, the key task is timely and guaranteed delivery of information received by monitoring tools to end users and decision-makers.

Goal. To ensure guaranteed and timely delivery of information from monitoring tools to final consumers of information, it is necessary to develop an analytically sound methodological apparatus that takes into account not only the change in the structure of the monitoring system caused by the mobility of its tools, but various configurations of the monitoring system itself.

Results. This paper presents the key elements of the methodology for assessing the continuity of information interaction in monitoring systems with a dynamic structure, which is a development of the application of the structural-dynamic approach to modeling data transmission networks. The statement of the problem of communicating information to the consumer in monitoring systems with a dynamic topology is formulated and justified. In the terminology of vector discrete optimization, the problem of communicating information is formulated as a multicriteria problem of covering (subgraph) of a dynamic graph with simple intersecting chains whose end vertices correspond to pairs of information tools and information consumers. For a multicriteria problem, Pareto solutions are constructed and the possibility of their additive combination is substantiated.

An indicator of the continuity of information interaction in monitoring systems with a dynamic topology is introduced and justified. The proposed indicator allows us to assess the continuity of information interaction in the monitoring system with its various configurations or sequence of configurations, i.e. reconfiguration. The formalized representation of the system configuration takes into account, among other things, the multicriteria problem obtained in the port solutions, i.e. in the sequence of system configurations within the framework of the proposed methodology, various combinations of information tools and information consumers can be taken into account. Practical and theoretical significance. The calculation of the continuity index for the model sequence of configurations confirmed its adequacy and objectivity in assessing the continuity of the information interaction of the reconfigurable monitoring system.
