摘要： 针对网格计算经济的不足，提出了一个基于信任约束和价格控制的资源调度经济模型(RCMM)。该模型以资源信任度、GSC和GSP信誉度为基础，进行资源选择。在价格协商过程中，以供求关系控制Tâtonnement过程。仿真实验证明，RCMM模型改进了调度违约率，促进了价格稳定性并为任务选择了可靠性高的资源。

Abstract: Aiming to overcome the shortcomings of economy model in grid resource scheduling, this paper presents a restricted commodity market model(RCMM) which employs trust and price control in resource selection. The trust includs resource credit, grid services consumer credit and grid services provider credit. Price control is implemented by Tâtonnement process, in which price depends on supply and demand. Simulations are performed to compare the RCMM scheduling and none minimisation algorithm. Results show RCMM scheduling reduce breach of faith, improve the stability of price, select credible resource for task and help task agent evaluate a given resource allocation for robustness against uncertainties.
