Description: 在操作系统中，由于进程总数多于处理机，它们必然竞争处理机。进程调度的功能就是按一定策略、动态地把处理机分配给处于就绪队列中的某一进程并使之执行。根据不同的系统设计目标，可有多种选择某一进程的策略。有两种基本的进程调度方式，即剥夺方式(preemptive mode)和非剥夺方式(non-preemptive mode)。前者指就绪队列中一旦有优先级高于现行进程优先级的进程出现时，系统便立即把处理机分配给高优先级的进程。当然，被剥夺了处理机的进程的有关状态和上下文都必须妥善保存以便今后恢复。后者是，一旦处理机分给了某进程，除非该进程的时间片已满或它主动放弃处理机引起进程调度的原因与操作系统的类型有关，大体可归结为以下几种：
(1) 进程运行完毕
(2) 进程提出I/O请求；
(3) 进程执行某种原语操作(如P操作)导致进程阻塞；
(4) 时间片已满；
(5) 可剥夺方式中，就绪队列中某进程的优先级变得高于现行进程；，系统不得以任何理由剥夺该现行进程的处理机。
-the operating system, due process than the total number of processor, and they will compete processor. Process scheduling function is to a certain strategy, Dynamic processor allocation of land to put in place a cohort of the implementation process of making it. According to various system design objectives, can have a wide choice of a process strategy. There are two basic process scheduling, that is deprived of means (preemptive mode) and non-denial mode (non-preempti 've mode). The former refers to ready queue once they have priority over the current process priority class process, the system will immediately processors allocated to high-priority process. Of course, the processors are deprived of the process of the state and context must be properly preserved for future restoration. Platform: |

Description: 要解决三个冲突:1.同一老师任两门以上课程的在同一时间内安排在不同的班讲课 2.不同的课程在相同时间内安排在同一教室
3 .教室容量与学生人数的冲突
数据库:班级表(班级名称,人数) 教师表(教师名称,所教科目)
科目表(科目名称,总学时数,周学时数) 教室表(教室名称,容量)
我不知道还需不需要一个时间表??
要求:每天上下午各开4节课,每周按5天上课,一共18周.每次两节课一起上.
在排课时,每周所开的课程的总学时数要小于周学时数.
多学时课要隔一天以上才上第二次课,
同一门课尽量在通一个教室上.
教室容量大于班级人数
主要解决上面的三个冲突.
我的数据库是用来实现输入功能的:一个排课计划表,其中包括(班级名,课程名,周学时,总学时,教师名)
然后就是在上面要求的基础上排课,输出

Description: 我校科技楼北楼有两台电梯。等电梯的人给出要上下的信号，电梯只有在空闲或同方向行进时才接受这个指令。然而，电梯经常出现十分拥挤的状况，特别在上下课的时候，要等很长的时间，所以埋怨声很多。你能否为电梯设计一个调度方案，减少大家的等待时间，减少师生的不满。-Our School Building North Building has two elevators. Such as elevators were given to the signal from top to bottom, the lift only when the idle or the same direction when the road to accept this command. However, the elevators are often very crowded, particularly in the last class when we have to wait a very long time, so many complain about the sound. Are you able to lift the design of a scheduling scheme to reduce the waiting time for everyone to reduce the dissatisfaction of the teachers and students. Platform: |

Description: 随机自动分班级排学号软件
一个朋友在中学教书，经常为排班级排学号头痛，于是做了这么一个小软件让朋友用用，反馈感觉上还不错。
本软件适用于小学升初中只有两科成绩,且成绩只有A,B,C三个标号.
说明一下:该随机自动分班级排学号软件,
不仅有有考虑到,成绩的均匀,
还考虑到生源地(即原毕业学校),性别,及班级学生个数的均匀.
一般来说,每个班级的总体都比较均匀
具体的说明，可以运行一下本软件，点一下生成源文件样本，然后参考一下即可。-Random Automatic Class scheduling software school No. A friend of mine to teach in secondary schools, often for the Class Pai Pai Student headache, then to do so, a small software that allows friends to use, and feel pretty good feedback. This software applies to primary and junior high school only two subjects, and the results only A, B, C grade three. Explain: The random Automatic Class No. Pai school software, not only has to take into account, results in uniform, but also taking into account the students (ie the original graduate schools), gender, and class number of the uniform. Generally speaking, each Class are relatively uniform overall specific, you can run like the software, click the source file to generate samples, and then reference click. Platform: |

Description: 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.
