Abstract: Resource management is the central part of Grid computing system and the model is a prime concern. A lot of models have been brought forward by researchers and the most highlight is the computational economy model. In this paper, a credit model in which the resource credit, GSP credit and GSC credit model were defined was presented. In contrast to traditional resource management, the credit is public in Grid-wide according to the need and Integration into resource allocation algorithm. Then the implementation of the model was proposed and the credit algorithms, including the problems of Extended Resource Usage Record(ERUR) were designed. At last, some emulation experiments were offered to show that the credit model was efficient and valuable within Grid computing economy environments.
