要約(日本語): The widespread availability of networked environment has revolutionized the way that contemporary business operates. To manage services on the Internet has become more and more complex and time consuming for service providers since the service are changing rapidly and need to be updated. Users of services are unspecified and distributed all over the Internet and can scale from thousands to millions almost instantly. Due to the advent of electronic commerce, the need for flexibility, adaptability and rapid response time to information services system has become increasingly important.

In order to achieve the requirements Autonomous Information Service System is a proposition made to cope with the continuously changing conditions of service provision and utilization in current information systems. Faded Information Field (FIF) has been proposed as a distributed information service system architecture that is sustained by push/pull mobile agents to bring high-assurance of services through users' preference-oriented information provision on supply-demand basis. When users' demand changes, the information environment is dynamically restructured to achieve the same response time for all unspecified users. In this paper how to tradeoff push time and pull time based on FIF is discussed. The effectiveness of the proposed technology is shown through numerical evaluation. Our evaluation result shows that the appropriate structure of FIF can improve the total users response time compared with conventional system.
