Abstract-Web services are developed independently and deployed in a distributed environment, new service can be obtained by composing existing ones. The rapid introduction of new services also results in undesirable interactions between services. These conflicts are not mismatches of interfaces, but are usually based on the data in the executing instance and therefore runtime management of conflicts in Web services should be considered. We study the problem from the perspective of user's revenue, and propose an online approach to resolve conflicts is proposed 1 .
