由于在单道批处理系统中,作业一投入运行,它就占有计算机的一切资源直到作业完成为止,因此调度作业时不必考虑它所需要的资源是否得到满足,它所占用的CPU时限等因素。 每个作业由一个作业控制块JCB表示,JCB包括如下信息:作业名、提交时刻、所需运行时间、所需资源、作业状态、链指针等。 在程序开始时对用户提交的作业按作业调度算法排列,用链表形式存储,这里分别采用先来先服务、短作业、响应比高者优先调度算法对作业进行调度。这里为了操作者的方便,每个作业无论所需运行时间多少,都是每敲一次键盘就执行完一个作业。每个作业完成后打印作业的开始运行时刻,完成时刻,周转时间和带权周转时间,一组作业完成后打印这组作业的平均周转时间,带权周转时间。所以要在运行时对运行时间进行记录,这里设置几个全局变量:T时间量; ttime总周转时间; trtime总的带权周转时间。-Road due to the single-batch system, and put into operation an operation, it has all the resources of the computer until the operation is completed, the dispatch operation when it's not necessary to consider whether the resources needed to be met, it occupied by the CPU time and other factors.

本程序需要用到数据结构中队列的概念完成。用指针指出下一个进程的PCB首地址,最后一个进程中指针为“0”。该调度算法是从后备队列中选择一个或若干个估计运行时间最短的作业,将其调入内存运行。当要求运行时间不为0时,将PCB加入队列(按优先数大小插入,且置队首标志);若要求运行时间为0,则把它的状态修改为“结束”(),并退出队列。-the procedures need to resort to queue data structure to complete the concept. Using indicators under a process that the PCB first address, the final process of a target to "0." The scheduling algorithm from the reserve queue is a choice among a number of estimates or the shortest run the operation, the redeployment of its memory operation. When asked for running time 0:00 a.m., the PCB will join the queue (by inserting small number of priority, but the first signs of home team); if the running time to 0, ruled the state to "end" (), and to withdraw from the queue.

The Class Scheduling Problem (CSP) is concerned with assigning a number of courses corresponding to various students and instructors to classrooms taking into consideration constraints like classroom capacities and university regulations. The problem also attempts to optimize the performance criteria and distribute the courses fairly to classrooms depending on the ratio of classroom capacities to course enrollments. The problem is a classical scheduling problem and considered to be NP‐ complete. It has received some research during the past few years given its wide use in colleges and universities. Several formulations and algorithms have been proposed to solve scheduling problems, most of which are based on local search techniques. In this project, we use a hybrid algorithm which combines features of Genetic algorithm and Branch and Bound algorithm to solve the class scheduling problem. -The Class Scheduling Problem (CSP) is concerned with assigning a number of courses corresponding to various students and instructors to classrooms taking into consideration constraints like classroom capacities and university regulations.
