摘　　要：针对计算网格资源的特点,提出一种基于风险策略的多单元连续双向拍卖的网格资源分配机制,实现对网格资源灵活有效的管理。首先,介绍了基于多单元连续双拍卖的网格资源分配框架。其次,针对计算网格资源的有限性,提出了RB2-MCDA机制。RB2-MCDA机制是在多单元连续双向拍卖中,代理采用Risk-Based2策略进行资源交易。Risk-Based2策略是一种基于风险行为的代理策略。实验结果表明,在不同规模的有限资源的计算网格中采用RB2-MCDA机制能够实现较高的资源分配效率,当资源需求量接近供给量时,分配效率超过99%。This paper proposed a decentralized mechanism to solve resource allocation for computational grid where sellers have finite production capacities and a cost structure composed of a fixed overhead cost and a constant marginal cost.The RB2-MCDA mechanism is that agents use risk-based2 bidding strategy for transactions in MCDA.Such mechanism is required when a system consists of multiple self-interested stakeholders of which each possesses private information that is relevant to solving a system-wide problem.T...
