基于遗传算法的排课系统设计
陈常涛
一、
数据库设计
概述
排课问题是一个多因素的组合优化问题，属于
NP
完全类问
题。
传统的方法难以得到高质量的课表，
而采用遗传算法能
更有效地得到更优化的课表。
需求分析
排课问题有是关于教师，
班级，
时间，
教室以及课程的多因
素优化决策问题。
所以本系统要求实现以下功能
1
．
在得出的课表中教师不能再同一个时间片段同时上两
门或两门以上课程。
2
．
在得出的课表中一个班级在同一个时间片段内不能同
时上两门或两门以上课程。
3
．
由于教室容量有限，
所以在同一个时间片段内在该教室
上课的班级的人数之和不能大于教室的容量。
4
．
在同一个教室上的课必须是同一门课，
并且是同一个老
师教的。
5
．
所有的课程按照上学期某各个学院的开课计划来安排
概念结构设计
