The Research And Implementation Of Dynamic Web Services Composition Based On Agent Technology

Recently, many attentions are put on the integration of agent technology with web service technology in order to provide novel ways to develop heterogeneous and diverse software systems deployed in Internet. Until now, there is no general technology framework of web service to support the development and configuration of web service, and to implement automatic operation, self-interaction and dynamic integration of sevices. Agent technology has such advantages as autonomous behavior and natural modeling, and enhances the capacities of interaction and dynamic adaptation of web services.This thesis proposes the approach to web services dynamic composition based on agent technology and BPEL4WS. The approach implements the composition and exe-cution of web services,and supports the dynamic configuration of multiple cooperative and uncertain business processes. The thesis presents the technical framework of dy-namic services composition, and designs and implements the corresponding software agent. A software prototype of travel assistant system is developed to demonstrate the effectiveness and feasibility of the above approach and framework.
