This study discusses the utilization of three types of relationships in performing data replication. As grid computing offers the ability of sharing huge amount of resources, resource availability is an important issue to be addressed. The undertaken approach combines the viewpoint of user, system and the grid itself inensuring resource availability. The realization of the proposed strategy is demonstrated via OptorSim and evaluation is made based on execution time, storage usage, network bandwidth and computing element usage. Results suggested that the proposed strategy produces a better outcome than an existing method even though various job workload is introduced.
