Abstract :
If Grid computing is to experience widespread commercial adoption, then incorporating risk assessment and management techniques is essential,both during negotiation between service provider and service requester and during run-time. This paper focuses on the role of a resource broker in this context. Specifically, an approach to evaluating the reliability of risk information received from resource providers is presented, using historical data to provide a statistical estimate of the average integrity of their risk assessments, with respect to systematic overestimation or underestimation of the probability of failure. Simulation results are presented, indicating the effectiveness of this approach.
