The research of calculation model of QoS for service composition based on 0-1 programming
Web Service is the best realization of SOA, which plays an important role in service computation. With the continuous development of service composition and increasing diversification of business demands, there are more than one solution can be proposed to provide the similar service. Under such circumstances, how to measure the quality of solution quantitatively becomes the research focus of service composition field. In this paper, we analyze the key factors of composite service from domain and runtime angle and classify the elements into three types by using HTN planning, besides this, an calculation model for value of composite service quality is constructed based on the 0-1 programming and implement an instance of service composition with this methodology.
