Service composition supports the automatic construction of value-added distributed applications. However, this is nowadays mainly a static affair, with compositions being built once and for all. Moving from a static to a dynamic world, where both available services and needs may change, requires automated techniques to correct broken compositions. Recomposition is a working solution but it requires to rebuild composition models from scratch. With graph planning as the service composition framework, we propose repair as an alternative to recomposition. Rather than discarding broken compositions, repair reuses and corrects them for fast generating new service compositions. Our approach is completely tool-supported. This enables us to compare repair and recomposition using both a case study and a data set from a service composition benchmark framework.
