Reputation systems have emerged as a method for fostering trust amongst strangers in electronic transactions. In this paper we propose a utility-based model for reputation tailored for service-oriented computing. In contrast to most other reputation models that require direct feedback from users, our model build the reputation from information provided by monitoring systems, making it suitable for service-oriented settings such as Grids. Usefulness of the model is described by showing how the efficiency of resource brokering in Grids can be improved by using a reputation-based scheduler scheme.
