In the context of the progressive incarnation of Grid systems in terms of a Service Oriented Architecture, it is essential to improve the automatic evaluation and selection of Grid services. Current mechanisms for service evaluation lack expressiveness as regards the representation of service requesters' expectations. In this paper, we present a model for the quantitative expression of service attributes, for the association of the possible values of these attributes with the requester satisfaction and for the aggregation of a set of satisfactions in an overall score by means of different aggregation logics. The proposed approach enriches the expressiveness of the mechanisms for the evaluation of Grid services. Copyright © 2005 John Wiley & Sons, Ltd.
