Abstract

A great development of Web technologies requires the application of complex systems and algorithms for maintaining high quality of Web services. The paper presents application of a broker-based architecture to the globally distributed Web system and the deployment of adaptive request distribution algorithm using neuro-fuzzy models in the decision-making process. The presented results of the simulation experiments show how the Web system operates under control of the proposed algorithm and the way of adaptation of the system to time-varying environment.
