Grid resource management system is regarded as an important component of grid computing. In this paper, a novel abstract owner (AO) resource management model is designed and investigated. Firstly the general architecture model and AO execution mechanism are analyzed, and then a competitive auction mechanism utilized in market -driven economics proverbially is introduced into the ordinary AO resource management model to adapt the dynamic and scattered resource characteristics. Furthermore, a resource management prototype system developing client broker and multi-auctioneer is designed and implemented as a solution for resource complexity and scheduling bottleneck. On one hand, the advanced AO resource management model can manage grid resources more effectively and improve the resource discovery and selection performance significantly. On the other hand, the dishonest auctioneer 'fraud action as well as user's partnership fraud action can be prevented from in AO resource management model depending on multi-auctioneer. Finally, some related algorithms for the new auction framework are proposed correspondingly to realize the architecture model.
