Abstract
Recently, there has been a growing fashion for businesses to outsource parts of their processes, so as to emphasis more on their core activities. In addition, Web operators often need to compose different services to achieve a more complex task that cannot be fulfilled by an individual service. Web services provide the means for such seamless integration of business processes across organizational boundaries. How to integrate the existent Web services to form a newly value-added and complex service to meet the requirement of different users is a popular research area. This paper discusses the composition of Web Services using QoS. The idea is based on the assumption that for each task in a workflow a set of alternative Web Services with similar functionality is available and that these Web Services have different QoS parameters and costs. Web Service selection with QoS global optimal is transformed into a multi-objective services composition optimization with QoS constraints.
