Dynamic composition of web services based on Qos parameters using fuzzy logic

Composition, the process of combining many constituent web-services representing a workflow, is one of the crucial research issues of Service Oriented Architecture. QOS parameters being the illustrious basis for the composition of webservices is the motivation for writing this paper. Since the selection of web-services among many of them with the overlapping functionality is a decision problem, to satisfy user´s end-to-end QOS requirements. So, to provide a smart choice to service providers to choose the best services for composition, this paper is a stupendous contribution as it comes up with a membership function that easily prioritizes the candidate webservices with the similar functionality to a more finer level on the basis of their response time so as to get selected for the composition as well as maximizing the user´s satisfaction.
