Description: 程序用C++模拟了操作系统中的三种最典型的简单的静态进程调度算法；先由用户动态输入生成模拟进程，使用了26种可供用户选择的典型语句（包括循环、选择结构），可处理整型、布尔型与字符型三种数据与表达式计算；程序编制时主要采用的编程技术是：用语句链表记录进程语句，并用PCB链表,就绪队列链表,阻塞队列链表,执行队列链表,结束队列链表等数据表示进程处理过程中的相互关系，由于静态数据结构不适合处理数据量大小不定的数据，而动态队列结构适合于处理数据量大小可变数据的处理，因此在程序中采用动态链表对这些数据进行处理；使用信号量、P.V.操作实现进程的同步与互斥，模拟进程在操作系统中的运行-procedures C to simulate the operating system, the three most typical process simple static scheduling algorithm; First generation user input dynamic modeling process, the use of the 26 options are available to users of typical statement (including the circle, choose structure), can handle integer, boolean and three character expression data and calculation; the main procedures for the preparation of the programming technology : Listless statement recorded statement process, and PCB Chain, ready Queue List, blocking Queue List, the Executive Queue List, ending Queue List data processing, said the process of mutual relations, due to static state data structure is not suitable for handling data on the size of the volatile data, and dynamic queue structure suitable for data processing variabl

Description: 调度的实质是操作系统按照某种预定的策略来分配资源。进程调度的目的是分配CPU资源。由于进程调度程序执行的频率很高，因此调度算法的好坏直接影响到操作系统的性能。本实验的目的是编程模拟实现几种常用的进程调度算法，通过对几组进程分别使用不同的调度算法，计算进程的平均周转时间和平均带权周转时间，比较各种算法的性能优劣。

Description: 1)编程实现模拟操作系统进程调度子系统的基本功能；理解进程调度的概念，通过课程设计深入了解进程控制块的功能、进程的创建、删除以及进程各个状态间的转换过程；实现先来先服务、时间片轮转、多级反馈轮转法对进程进行的调度过程；通过观察有关的队列结构的内容的动态变化过程深入体会各个调度算法的特点；从而能够更好的巩固从书本上学到的知识。
2)编程过程中需要建立队列等结构进行各种操作，通过该次试验，可以督促学生从实用的角度对《数据结构》课程内容进行更深入理解和更熟练的应用。
3)实验编程语言要求使用java语言或C++语言。通过对调度功能的编程实现，不但能有效训练学生对编程语言的熟练使用，还能促进学生独立思考解决问题、以及独立查新获取知识的能力

The purpose of the process of scheduling is to allocate CPU resources. Since the implementation of the process of a high frequency of the scheduler, the scheduling algorithm will directly affect the operating system performance. The aim of this simulation is to achieve some common programming process scheduling algorithm, the process by several groups using different scheduling algorithms, respectively calculate the average turnaround time for the process and the average turnaround time with the right to compare the performance of the merits of various algorithms.

Description: 1)在Linux下用C语言编程模拟优先级程调度算法。为了清楚地观察每个进程的调度过程，程序将每个时间片内的进程情况显示出来。2)进程控制块是进程存在的唯一标志，因此，在模拟算法中每一个进程用一个进程控制块PCB来代表，PCB用一结构体表示。3)进程在运行过程中其状态将在就绪、执行、完成几种状态之间转换，同时进程可能处于不同的队列中，如就绪队列。在优先级调度算法中，选择单向队列，入队既是将进程控制块插入队尾，出队既是按优先级重新排列的队，删除队头元素。4）为了便于处理，程序中的某进程运行时间以时间片为单位计算。各进程的优先级认为输入，运行所需时间随机产生。5）优先权调度算法采用动态优先权，进程每运行一个时间片，优先数减1；进程在就绪队列等待一个时间单位，优先数加1。6）对于遇到优先权一致的情况，采用FCFS策略解决。7）由于是模拟进程调度，所以，对被选中的进程并不实际启动运行，而是修改进程控制块的相关信息来模拟进程的一次运行。-1) Linux emulation priority process scheduling algorithm using C language programming. In order to clearly observe the scheduling process for each process, the program will process each time slice is displayed inside the case. 2) process control block is the only sign of the existence of the process, therefore, in the simulation algorithm each process with a process control block PCB to represent, PCB represented by a structure. 3) processes in operation status will be ready to perform, to complete the conversion between several states, while the process may be in different queues, such as the ready queue. In priority scheduling algorithm, choose unidirectional queue, the team is not only a process control block into the tail, the team both teams prioritized rearrange, remove the head elements. 4) In order to facilitate processing, the program run time of a process to calculate the time-piece. The priority of each process that the desired input, run-time generated randomly. 5) priority
