Labzhinsky V. Multiagent technology of synthesis distributed hierarchical data processing systems (with ecological monitoring DPS as an example)

In this dissertation has been considered questions of build topical distributed data processing systems. The work contains model of such a system with ecological example, main system elements and communications among them, an interconnection scheme has been built. Basic principles of development, creation and functioning informational and analytical systems have been considered. Expediency of usage multiagent technology has been justified for building such systems, adduced formal specification and building procedure. Also problem has been solved building a system with minimal operating costs per time unit. Functioning mechanism has been considered in the system progress, described working algorithms of all agents of the system. In particular, an optimal period of information replication has been determined, suggested approaches to optimal data aggregation, suggested adaptive algorithm to share query flow among secondary servers. Ecologically specialized agents have been built to index and search documents, basic parameters of search agent as a queuing system have been determined. Developed methods, models and algorithms were used within the framework of scientific and technical programme "GRANIT". The suggested procedure of building informational and analytical system and structuring documentary information approaches might be used to build similar systems, which have any topical content.
