- 649 abstract "Web service composition provides customized and flexible integration of existing service functionalities. Quality-of-Service (QoS) optimization algorithms select services in order to adapt workflows to the non-functional requirements of the user. With increasing number of services in a workflow previous approaches fail to achieve a sufficient reliability. In case of a service failure, expensive ad-hoc replanning is required. Thus, the major problem with this sequential application of planning and replanning is that these potential costs are ignored during the initial planning and consequently are hidden to the decision maker. Our basic idea to overcome this substantial problem is to instead compute an QoS optimized selection of services that includes a sufficient number of backup services for each employed service. In order to further facilitate the service selection task we apply a multi-objective approach and present a suitable service selection interface. Selections are ranked according to the risk preferences of the decision makers in this interface. We demonstrate the benefits of our approach by comparing it with existing heuristic algorithms in an extensive evaluation.".
