Abstract:

To solve the web service selection problem with hybrid quality of service(QoS) and lots of service composition plans, a hybrid qosclustering web services composition algorithm (CHQoS_WSCA) based on multiattribute decision making theory is presented. Not only CHQoS_WSCA takes all possible QoS expression types (real numbers, interval numbers, triangular fuzzy numbers and intuitionistic fuzzy numbers) into consideration, it also can effectively solve the service selection algorithm performance problem with largescale composition plans.

Key words: clustering, web service, service composition, multiattribute decision making theory, quality of service
