Hybrid QoS-Clustering Web Service Composition
Longchang Zhang, Chengwen Zhang · Beijing Youdian Xueyuan xuebao · 2011
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.
