MULTI-AGENTS SYSTEMS APPROACH FOR UNDERWATER SOUND EQUATIONS SOLUTION

摘要

Problems of underwater acoustic modeling using multi-agents systems approach are considered in the paper. It is well known that calculation and modeling of an acoustic field are rather difficult problems accounting for a lot of factors, and some of them are not numerical values or variables of binary logic of "yes" or "no" type; first and foremost the above factors are region type and parameters (e.g., deep sea, shallow water and other), some parameters of a sound source and sound receiver, a set of available computer and analytical models etc. At that as a rule the data incompleteness as well as their fast variability in time and space are specific for the considered problems. In many cases the use of conventional programming approaches, like object-oriented approach, leads to the development of numerous rather complex computer models for the underwater sound area, and their common disadvantage is that these products could be used only by the developers. The present paper considers an approach to the acoustic field modeling based on decomposition of underwater sound equations into a set of intelligent constituents - agents. The proposed approach includes the following stages: development of an ontology of the subject area; decomposition of underwater sound equations into a set of intelligent agents; development of a structure of each intelligent agent and its interface; development of a system of interaction between agents; development of underwater sound equations computer model based on a multi agent distributed system.
