The study of Web services composition model

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Web services are being adopted, more and more, as a viable means of accessing Web-based applications. Web services are not only used to exchange information between ,-enterprises but also help software developers to provide value- add services for various demands. At present, there is a trend towards deploying business processes as composite Web services, known as Web services compositions. Web services I compositions are synthesized by researchers from elementary web services, offering the opportunity for service providers (and application developers to create value-added services, through Web services composition. However, a problem exists in the current distribution process of Web services compositions: the general analysis and selection of services can be overly complex and un-systemic, for example, information I in Universal Description, Discovery and Integration (UDDI) are missed, uncompleted or inaccurate. Therefore, there is a need to manage composite Web services, based on these emerging technologies. But the research related to ranking, candidate services and selection of optimization strategies is sparse. Nothing has yet been published, that considers the I constraints of non-functional properties. In this paper, a systemic but complete composition process has been proposed, which shows great promise in the emerging demand for composite Web services. Also by proposing the new j constrained crossover and constrained mutation process, the Genetic Algorithm (GA) can operate effectively thus to produce an optimal solution (the best combination of Web services).
