摘　　要：总结分析了现阶段流行的一般磁盘调度算法和实时磁盘调度算法,并针对存储的实时业务的特性,提出了改进的调度算法,建立相对应的数学模型,最后通过模拟实验,验证了算法的有效性。Disk scheduling algorithm is very important for computer system to upgrade its values.As the real-time system increasing, it is necessary to research about real-time disk scheduling. This thesis discusses the usual disk scheduling algorithm and analyses one new way of real-time disk scheduling. The experiment on computer proves that the new disk scheduling algorithm is better.

关 键 词：磁盘 性能模型 优化调度算法 贪婪算法
