一种基于微观经济学的网格资源分配模型

A Microeconomics-Based Resource Assignment Model for Grid Computing

引入微观经济学知识,设计了一种双模式网格资源分配模型.在该模型下,根据供求关系影响提供者资源售价,以售价调节消费者资源占用量,支持提供者与消费者双赢的实现.在网格资源丰富时,采用博弈模式,基于Nash均衡和Pareto最优为消费者确定最优资源占用量,同时为提供者确定最优售价;在网格资源稀缺时,采用竞价模式为消费者分配资源.仿真结果表明,该模型是可行和有效的,具有较好的性能.

Introducing the knowledge on microeconomics into grid computing, a dual-scheme resource assignment model is therefore developed. The way the supplier＇ s selling price affected by supply-demand relation is used to adjust consumer＇s occupancy of grid resource so as to support the implementation of a win-win relationship between the supplier and consumers. If the available grid resource is plentiful, the game playing scheme is used to determine the optimal resource occupancy for consumers on the bases of Nesh equilibrium and Pareto optimality, with the optimal selling price determined for the supplier. If the grid resource is scarce, the bidding scheme is used to assign the grid resource for consumers. Simulation results showed that the model is feasible and efficient with favorable performance.
