Abstract
Service composition mechanisms successfully enable ’programming in the large’ within business oriented computing systems. Here, the composability of single software components provides dynamicity and flexibility in the design of large-scale applications. However, this dynamicity is restricted to the late binding of services to service interface descriptions; the workflow, i.e. the execution order of the single services, remains static.
Within this paper, we present the modification of abstract service composition plans, extending service compositions’ dynamicity from late binding of service implementations to a dynamic reconfiguration of the service composition structure itself. As a proof of concept, we demonstrate the adaptability of the service composition plan by applying genetic operators on the workflow graph of the service composition. Finally, an evaluation mechanism is presented to estimate the degree of similarity between the resulting composition plan and present ones.
