Control Flow Complexity Metrics for Petri Net-based Web Service Composition
Web services technology is an effort to build a distributed computing platform over the network, and it can implement systematic application-to-application interaction on the Web. In recent years, this new technology has been widely adopted for constructing distributed applications. However, how to precisely measure the controlling complexity of Web Service Composition (WSC) is a very difficult task due to its characters such as heterogeneity, distributed and loose-coupling. In the paper, the authors mainly concern on the complexity measurement of Petri net-based business process in Web service composition.
