Summary:The reliability of service is related to the kind and the number of service resources in grid. The kind and the number of service resources often change, so the service reliability is variable. In this paper, we propose a reliability measurement model for service in grid, which is based on the dynamic characteristic of service resource. In this model, the dynamic state of service is divided into a series of relative stabilized states, and the difference of each relative stabilized state denotes a change of the service resource in the kind or the number, we propose three index values, namely the reliability of service, the mathematical expectation of reliability and the mean square deviation of reliability, to measure the reliability quality of service. In order to show the feasibility and the availability of this method, a case study is described. The results show that it is feasible and efficient to measure the reliability of service in grid.
