Abstract: In this work we present an integer programming-based algorithm for adapting the execution of WS-BPEL scenarios, through the dynamic selection of the services to be invoked, according to criteria and policies set by the user. The proposed algorithm is experimentally evaluated both in terms of adaptation quality and adaptation computation overhead. The experimental results demonstrate that the proposed approach achieves to considerably improve adaptation speed, as compared to the exhaustive search algorithm which is considered as a baseline, while at the same time maintaining adaptation quality.
