    针对Nimrod-G系统中DBC调度策略只能集中对一个目标（时间或费用）进行优化的问题，提出了基于平均成本的DBC分类调度算法，该算法综合考虑了任务调度的完成时间和费用。通过GridSim仿真实验证明，基于平均成本的DBC分类调度算法在均衡完成时间和费用方面有很大的优势，有效的扩展了原有算法。

    Aim at problems that the Deadline and Budget Constrained scheduling policy can optimize one target of the two QoS targets(time and cost), we proposed average cost based DBC classified optimization algorithm. It considers both the time and cost of task scheduling. The result of simulation experiment shows the new algorithm has good performance on balance the time and cost of task scheduling and effective extending former algorithms.
