AbstractThe subject matter of the study is the integration and management of information resources of distributed computing corporate systems within the common information space. The goal of the study is to develop scientifically based models for supporting intelligent technologies for the integration and management of information resources of distributed computing systems. In accordance with the goal of the study, the article deals with the following tasks: to develop a formal-logical model of the information space, to study and formalize agent-oriented tasks, to select the model of a software agent, to substantiate the information technology aimed at effective information management in corporate systems. The following results were obtained: a formal model of the information space of a corporate information system was developed; the role and place of a user of the information system resources were determined; the concept of the task and the flow of user tasks in the information space were considered and formalized; the definition of a software agent, multi-agent space and a multi-agent space management system were suggested; the model of the frame structure of knowledge representation modified by the authors is proposed as a logical model of a software agent. Conclusions. The analysis of domestic and foreign sources showed that the study in the field of integration of information resources of distributed systems and building a unified information space does not fully meet the modern requirements of users and developers of application software. Existing solutions based on integration technologies do not allow heterogeneous information structures to be actually integrated. Basing on the study of the main business processes in information systems "user - information environment", a model of information multi-agent space of a computer system was developed and investigated. The main components of a multi-agent system were identified and basic entities were formally defined as a software agent and a multi-agent space. The agent-oriented approach to solving managerial problems and integrating information resources of distributed computing systems was formulated and substantiated.
