The paper discusses topical issues of modern information searchsystem development. These systems are the main search tool that can be used to search in the Internet. In addition, there is a stable trend to intellectualization of infor-mation search systems and search personalization. These searchengines are oriented to eliminate major disadvantages ofthe traditional context keyword search. We propose to use the artificial intelligence methods and, in particular, multi-agent ap-proach, methods and tools of plausible case-based reasoning for personalization and intellectualization of searching. A sim-plified structure of the Internet search engine and the main tasks of such engines are considered. We propose an architecture based on intelligent agents, providing the opportunityto Internet resources case-based search. The components of the pro-posed information search system architecture and main modules software implementation in MS Visual Studio 2010 using FIPA (Foundation for Intelligent Physical Agents) standard and ASP.NET technology under MS Windows operating system are considered in detail.

The article describes the concept of design objects, their correlation and the component structure in relation to the space instrumentation problems. Information systems and technologies to support the processes of product design are considered. The scheme of diverse information entities structured storage in the data management system is shown. The as-pects of the conceptual design of a information system data model to support the product life cycle, including integration with CAD systems are supplied. The article conseders the need of electrical and mechanical engineering equipment, the classes of data models allowing describing the composition and the relationship of design objects. The UML-diagram that illustrates the hierarchy of object types and relationship of design as anexample of electronic equipment is developed.

This paper introduces a stochastic multi-agent model to reproduce key empirical properties of the real order book dynamics. The model includes three mechanisms: sending limit orders, cancellation of limit orders and sending market orders. The empirical properties of the order book of RTS futures contract are used as parameters of the model. The sequence of order book events forms a Poisson flow. Order size has power-low distribution. The proposed model is able to reproduce several empirical features of the high-frequency dynamics of the orders in the book and price movements.

The chronological express analysis of the approaches to constructing high-speed CAD electronic schemes is given. The attention is directed to the fact that the systems of automated designing should satisfy the interactivity require-ment. This requirement can be realized when the system gives replies to the user inquiries with a delay not exceeding2-3 se-conds. In the conditions of constant increasing of projected objects complexity the maintenance of automated designing sys-tems interactivity is impossible without constant escalating of their high-speed properties. The article considersthree essen-tial directions of CAD interactivity maintenance. Taking into account general expansion of network technologies, using the potential of various kinds of networks for creation of distributed CAD is a perspective and promising direction of researches. There is the structure developed by authors and the results of imitating modeling of distributed CAD that substantiated the expediency of constructing a real subsystem of designer projecting of electronic schemes. The basic modules of the subsys-tem, their functioning and results of experimental researches are described. Experimental researches have shown that the de-veloped subsystem is referred to the type of GRID-systems and allows reducing time of projecting to 3 times.

The paper describes the software to design rule-based expert systems. The software includes MDA methodolo-gy (Model Driven Architecture) and is intended for non-programmers. MDA is based on the stepwise transformation of do-main models. The proposed methodology feature is using ontology as a computation independent model (CIM); RVML (Rule Visual Modeling Language) as a platform independent model (PIM); JESS as a platform specific model (PSM). The architecture, main modules, functions and the universal logic data model for storing and interacting ontology and rules are presented. The RVML (designed to describe the rules with theaid of graphical primitives) is described. RVML increases the efficiency of rule-bases development by improving the clarity and comprehensibility of visualization of cause-effect relations (as compared with UML).

The inventive task is represented in the form of the conceptual scheme of system tasks universal solver. The system task types are defined together with solution methods of these tasks on the computer. In the context of sistemology, system conceptual design is represented as lifting process on epistemological hierarchy of systems. At the fist stageof con-ceptual design the generating system representing a task for the system to execute is defined. At the second stage the struc-tured system meeting four certain requirements is defined. Example of this approach realization is creating the synthesis method of heuristic inventive receptions based on sistemology.

The paper formes the objectives, principles, common architecture, functional features and the basic require-ments to creating a new multifunctional information system ofthe RS ISS crew activities support, based on the results of analysis and research of the methodical ware existing system.The space object performance script is the detailed daily flight plan that is created using a distributed international planning system. The main purpose put in the crew and groundsupport group information ware is the timely provision the user with the necessary methodical and control information at theright time in an accessible terminal. To do this, a user interface module project is offered. It is the mechanism of mapping and us-ing on-board interactive instructions on ISS RS crew actions. The requirements for this application are defined, a prototype is created and studied during the space experiment. Using XML technology allows achieving relevance of provided content based on a single source of information. Virtual interactive guides widely using multimedia information changed information perception and understanding. Integration of ground and onboard facility with MIS in RSC "Energia" corporate system al-lowed raising the level of information support and the space system efficiency.

The apparatus of color Petri nets in respect of its use in intelligent systems of real time is considered. Petri nets allow to describe naturally synchronization, overlapping, the conflict and causal dependence, and also visually to represent a structure and behavior of difficult technical or organizational systems. However, an essential drawback of classical Petri nets is complexity of modeling real time systems when it is necessary to consider a factor of time and temporal dependences. New expansion – color Petri nets with support of Allen’s temporal logic, allowing to model both quantitative, and qualitative temporary delays is offered. This logic is characterized by sufficient expressiveness and existence of polynomial algorithms of a conclusion that its practical application in intelligent systems like intelligent decision support systems of real time allows. The description and the example of use of the developed basic software for this class of Petri nets is given.
