零碎介绍

因为现代科技的疾速倒退，相干管理人员应用线上零碎来治理的形式逐步衰亡，因为它使治理更加简略与不便，对于传统排课来说，要让工作人员手动进行设计，这种既费时也费劲。所以依据现有的教学资源，用古代技术设计一个具备算法的主动排课的零碎。此零碎可能不便学生更好的查看课表，有助于老师在线实时安顿课程，学生也能实时获取到课程信息，同时整顿大量数据，能很好的查看历史数据信息。自定义化的晋升，让老师和同学们都更灵便的工夫来安顿，从而缩小相干管理人员的累赘，更加不便管理人员的治理。

本文采纳B/S框架联合Vue技术来设计而在算法上次要应用遗传算法来进行实现，此外还查阅肯定的材料和参考了理论的需要加上大量的我的项目来进行剖析与设计。实现了能够主动排课的性能，特地翻新地应用了遗传算法等相干技术来让排课这个过程变得更轻松。从而达到了疾速排课的后果，也让工作人员又有了空余工夫来重复查看与保护。最初零碎为了保证数据长久化须要应用数据库来保留数据，因而应用MySQL数据库来保留。

关键词：遗传算法；排课；Vue；MySQL

排课零碎在性能上次要划分为三个模块别离对应三种角色，管理员（教研室主任、学院秘书、教学院长、教务处），老师（助教、老师、副教授和传授），学生。别离对应的性能是，学生：集体信息管理、学习治理、查看课表，老师：集体信息管理、班级治理、学生治理、教学资料治理、课程管理，管理员：年度教学工作、专业课师资安顿，学院教学工作审核、销假调课审核、院级审批，老师治理、学生治理、教学资料治理、教学设施治理、班级治理、排课治理、课程管理、查看零碎数据。但思考到应用排课零碎就是对课程进行安顿失去一个正当的后果，本质就是把与课程有影响的因素进行匹配。所以思考到上述划分的角色，因而对此排课零碎的零碎性能划分下面做初步设计。相干构造划分如图4-2所示：

环境须要

1.运行环境：最好是java jdk 1.8，咱们在这个平台上运行的。其余版本实践上也能够。
2.IDE环境：IDEA，Eclipse,Myeclipse都能够。举荐IDEA;
3.tomcat环境：Tomcat 7.x,8.x,9.x版本均可
4.硬件环境：windows 7/8/10 1G内存以上；或者 Mac OS；
5.数据库：MySql 5.7版本；
6.是否Maven我的项目：否；

技术栈

后端：Spring+SpringMVC+Mybatis
前端：JSP+CSS+JavaScript+jQuery

应用阐明

应用Navicat或者其它工具，在mysql中创立对应名称的数据库，并导入我的项目的sql文件；
应用IDEA/Eclipse/MyEclipse导入我的项目，Eclipse/MyEclipse导入时，若为maven我的项目请抉择maven;
若为maven我的项目，导入胜利后请执行maven clean;maven install命令，而后运行；
将我的项目中springmvc-servlet.xml配置文件中的数据库配置改为本人的配置;
运行我的项目，在浏览器中输出http://localhost:8080/ 登录
