Abstract—The determination of evolution type plays an important role in securing the accurate and efficient evolution of service composition. Based on the applied level in the evolution of service composition, using openbisimulation theory, evolution type can be decided from three dimensions, which are respectively single state node, single service and service composition, and the determination rule as well. The determination of evolution type for single state node can tell whether the external behaviors of the node has changed, while the single service can confirm the changes that the state nodes of the service have had in quantity and logic during the business process, and the evolution type of service composition can provide guidance for fixing the final evolution program. Finally, a case study of how to decide the evolution type of web service composition is offered to demonstrate the practical application of the above rules.
