GridDEV is a DEVS-based platform for evaluation of service grid. Through the analysis of SOA, we characterize important features of service grid and select four components as the base of grid modeling. With DSDEVS, this paper models the basic components selected, as well as the relationships between them. As a result, the model fully formalizes the gird system;hence facilitates the design and optimization of grid services. Based on this model, we map the DEVS component into elements of simulator development library SimGrid, and construct the platform GridDEV for grid performance and reliability evaluation.
