学校排课系统的设计

A学校排课系统的设计摘要当第一台计算机出现时，不仅意味着新型革命的到来，也预示着科技时代的来临。尤其是踏入21世纪后，计算机技术得到了空前的发展，而网络的普及使得各行各业逐渐离不开电脑。对于高校而言，在教务办公中已经越来越多的实现了自动化，既提高了工作的效率，也规范了教学的操作，增加了科学性。在分析以往一些排课系统的基础上，本设计提出一个基于动态加权算法（即贪婪法）的排课系统设计方法，采用手动预排、自动排课、手动调节的三级排课模式，并对一些具体的技术问题做出相应安排。在功能方面，它能实现查阅、修改、添加等比较基本的功能，也能够实现自动排课、权限管理等较复杂的功能。本设计采用C/S模式，主要用Delphi7.0作为前台开发工具，用SQLServer2003作为后台数据库。经过测试后，本设计已可达到预想中的效果，能够实现简易的功能。关键字：动态加权算法；自动化；C/S模式；三级排课模式DesignandImplementationofaUniversityAcademicCourseSchedulingSystemAbstractTheappearanceofthefirstcomputermeansnotonlythearrivalofanewtypeofrevolution,alsoheraldtheadventofthetechnologicalera.Particularlyintheadventofthe21stcentury,computertechnologyhasbeenunprecedenteddevelopment,andthepopularityofthenetworkmadebusinessesdonothingwithouttheassistanceofcomputer.Forcollegesanduniversities,theautomationoftheteachingofficehasbeenmoreandmoreachieved,whichcouldimprovetheefficiencyofthework,standardizetheoperationoftheteaching,andincreasescientific.BasedontheanalysisoftheformerCourseSchedulingSystem,thedesignputforwardtoamethodwhichisbasedonadynamicweightedalgorithm(greedymethods),itusesthemanualpre-arrangement,automatictimetableandmanualadjustmentofthethreemodels,andgetsthenecessaryarrangementstosomespecifictechnicalproblems.Concerningthefunctionofsystem,itachievesbasicfunctionswhichincludeaccess,modify,add,andcomplexfunctionslikeautomaticallyscheduleandcompetenceofmanagement.ThedesignusesC/Smode,withDelphiasfrontdevelopmenttool,andSQLServer2003asbackstagedatabase.Thoughtesting,thedesigncanreachthedesiredeffectandachievethesimplefunction.Keywords:Dynamicweightedalgorithm;Automation;C/Smode;ThreeLevelsCourseSchedulingModel目录论文总页数：25页1引言.................................................................................................................................................12基本理论知识介绍...............................................................................................................................12.1SQLSERVER2003数据库简介.....................................................................................................12.2DELPHI7.0简介..............................................................................................................................22.3C/S模式介绍................................................................................................................................43教务排课系统的设计与实现...............................................................................................................43.1教务排课系统简介.......................................................................................................................43.2教务排课系统分析........................................................................................................................53.2.1算法分析.............................................................................................................................53.2.2算法流程图...........................................................................................................................63.2.3功能分析...............................................................................................................................63.2.4需求分析...............................................................................................................................63.3排课系统的功能模块....................................................................................................................63.4数据库设计...................................................................................................................................73.5系统流程及代码分析....................................................................................................................93.5.1系统流程图............................................................................................................................93.5.2代码分析..............................................................................................................................104系统测试.............................................................................................................................................164.1测试环境.....................................................................................................................................164.2主要模块测试.............................................................................................................................174.3测试结果.....................................................................................................................................20结论..................................................................................................................................................20参考文献.................................................................................................................................................21第1页共25页1引言随着计算机的发展和教育改革的不断深入，计算机网络技术的不断成熟，综合教学网络已广泛应用于学校教学、管理的各个领域，特别是教务排课系统的应用。它代表着学校教学管理的水平，是现代化管理的手段。目前大多数教务排课系统是采用各教学单位进行教学任务的指派，然后将教学任务单提交教务科，教务人员将数据输入计算机，进行排课、打印课程表等工作。这种教务排课系统只是在一定程度上减轻了教务人员排课
