Multi agent Modeling and Visua Ization of Environment for Seagoing Craft
The article presents and describes an integrated system for acquisition, processing and presentation of
primary identification and measurement data on seagoingcraft environment. The offered multiagent
solution of integration task ensures eventdriven management for information processes both at level of
dynamic (sea and air) objects within control area and at level of information objects structuring input flows
of data on events in vessel environment. The developed software system (C#, .Net 3.5, .Net Remouting)
uses four layers of software agents A1, A2, A3 and A4, integrated into the comprehensive whole by
feasibilityproblem system of agents where the datatransportation system operates.
A task of identification of data incoming from multiple radars and a task of sea and air dynamicobject
grouping are introduced into the set of dataprocessing tasks and solved. The multiagent and multitask
features the development is based on, enable a range of approved opportunities of its development
including from the point of view of the systems use for vessel control.
The developed system has a training mode as a potential. This fact is an important advantage of the
developed system. Actually, the developed system has passed tests and confirmed its reliability for the
training purposes which are different from those of the complete set in the operating (main) mode using
sources of raw data flows. Manyagent modeling, visualization, vessel environment, integrated dataacquisition system.

Simulation Operation Model for Radio Equipment of Computeraided Dataexchange System
The article describes a simulation model of radioequipment operation for computeraided dataexchange
system created in order to evaluate influence of failure rate of radioequipment devices and time for
their recovery, on probability of uninterruptible dataexchange between computeraided dataexchange
systems of two ships during a longtime period.
The model of the operation process of radio equipment is developed using a mathematical scheme of
queueing system  Qscheme. The model response is an evaluation of the probability of uninterruptible
dataexchange between computeraided dataexchange systems of two ships during a longtime period.
The model factors are the following reliability parameters of each radio equipment: failure rate and recovery
time. The article also gives a blockdiagram of general algorithm of the radioequipment operation process
and blockdiagrams of procedures to define and change states of radioequipment devices simulated by
queueingsystem channels.
The simulation model is at the level of software implementation. The result of the software implementation
of the simulation model with values of the reliability parameters of radioequipment devices, given by
users, is an interval evaluation of probability of uninterruptible dataexchange between computeraided dataexchange systems of two ships during a time period given by users. The required accuracy and
adequacy of the evaluation are ensured by a required number of software iterations, calculated by the
programme, with the same initial data.
To evaluate the importance of factors (reliability parameters of radioequipment devices), a variance
analysis of each of them with response has been made. A combination of achievable factor values when
response values becomes the largest, has been defined by a method of coordinate raising. Simulation model, channel state, variance analysis, method of coordinate raising.

Models of Structuring and Formalization for Ontology of Application Domain At Stages of Computeraided System Designm
The article discusses an issue of error decrease during ontology creation at early stages of computeraided
system design including definition of classes and class hierarchy. Hierarchy depends on possible
ways to define a level of detail which is necessary for application, on personal preferences of analysts
and sometimes on requirements for compatibility with other models (verbal description of application domain, infological models, frames, semantic networks). It also deals with multiple guidelines to be taken
into account during development and optimization of ontology. The following features of structuring
and formalization of applicationdomain ontology at stages of design of computeraided systems, are
stressed: design of ontology is a constructive process which is to combine with objectoriented methods,
ways and approaches of structuring and formalization of application domain. Computeraided system, ontology, hierarchy, strata, application domain.
