A Web Service Composition Algorithmic Method Based on TOPSIS Supporting Multiple Decision-Makers
Hua Zou, Longchang Zhang, Fangchun Yang, Yao Zhao · 2010
This paper presents a novel Web service composition algorithm based on TOPSIS (WSC_TOPSIS) to solve the service composition difficulties with multiple decision-makers and heterogeneous QoS for the first time. It includes three main steps: normalizing decision matrix, evaluating alternatives synthetically and evaluating group alternatives synthetically. Experimental results show that the proposed algorithm can better support Web service composition with heterogeneous QoS data and multiple decision-makers.
