LARGE SCALE QOS-AWARE WEB SERVICE COMPOSITION METHOD USING EFFICIENT ANYTIME ALGORITHM

摘要

A QoS-aware web service composition method using an anytime algorithm is disclosed. The QoS-aware web service composition method according to an embodiment of the present invention comprises a step of reducing an example of a QoS aware web service configuration problem organized by a user request web service including a web service group and QoS information as an example of a graphic search problem based on a state transition system and a step of organizing an optimal complex web service capable of minimizing QoS by applying a dynamic anytime algorithm to the example of the graphic search problem.
