Abstract: Resource management is the prime concern of Grid computing system. Aiming at the economic models in the gird resource management, this paper proposes a credit evaluating algorithm and a resource selecting algorithm based on the concept of credit. At last, the paper implements it in scalable environment and the experiments show that the resource selecting algorithm based on the credit is efficient and valuable within grid computing economy environments.
