摘要：Grid computing environments have emerged following the demand of scientists to have a very high computing power and storage capacity. One among the challenges imposed in the use of these environments is the performance problem. To improve performance, scheduling and replicating techniques are used. In this paper we propose an approach to task scheduling combined with data replication decision based on multi criteria principle. This is to improve performance by reducing the response time of tasks and the load of system. This hybrid approach is based on a non-hierarchical model that allows scalability.
