With an increasing use of services sustaining the resources which people need has become more important. In this paper, we propose an effective reservation method, called “BPSR” (Business Process Service Reservation), which aims for the process reservation which to the best of our knowledge has not been studied before. In particular we address for major jobs: service differentiation; service reservation; process reservation and QoS Control. We also describe a flexible policy-based reservation method which aims to increase the success rate of reservation and utilization of service resources. Experimental analysis shows that the BPSR reservation system achieves better results than other reservation methods.

Feature interaction has been identified as a problem in the telecommunications domain in the 1980s, but since it has been shown to be a problem of systems that are composed of individually designed components. Clearly Web service composition is a way of building services from independently designed components and hence is subject to the same problem. This paper investigates the detection of feature interactions in Web services at runtime and proposes a novel detection method by taking inspiration from the Situation Calculus. Two case studies show that it is effective for detecting feature interactions in composite Web services.
