有多个访盘要求在等待时对这些要求的顺序的确定安排或调整，只在减少平均磁盘服务时间就成为磁盘调度，而磁盘调度有多种的调度算法，其中最短路径优先是其中基本一种，本课程设计是使用C++程序设计语言，在windows平台下对此调度算法进行模拟，通过此调度算法的模拟来进一步的加深对磁盘最短路径优先调度的了解，及对C++程序设计语言的使用。

-set to visit a number of requests waiting for the right time for these requirements in order to determine arrangements or adjustment. only the reduction of the average disk service time as disk scheduling, and the disk scheduling a variety of scheduling algorithm, shortest Path First which is a basic, the curriculum design is the use of C programming language, windows platform in this scheduling algorithm simulation, through this scheduling algorithm simulation to further deepen the shortest path to the disk priority scheduling understanding, and to the C programming language use.
