摘　　要：针对如何提高网格资源的使用效率和用户满意度及系统效率等问题,提出了一个基于层次调度模型的、将资源的表示与需求用XML方式描述、以模糊多目标决策理论为资源调度策略,以用户满意度和系统资源利用率为主要目标的综合网格资源调度算法。该算法不仅最大程度提高用户的满意度,而且较好地解决了网格资源的均衡使用,极大地提高了系统效率,对网格系统综合性能有明显地提高。Aimed at how to raise the utilization rate of resources and problems such as users satisfaction and system efficiency etc., a comprehensive grid resource scheduling algorithm is presented, which based on layer model, adopts XML resource representation and requirement description, introduces resource scheduling of fuzzy multi-objective decision making and takes users satisfaction and system efficiency as a main target. The scheduling algorithm can not only satisfy the demand of users at large, but also balance system load. Performance of grid system is improved.
