某高等学校教务排课系统的设计与实现
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SQL Server 2003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。

Design and Implementation of a University Academic Course Scheduling System
Abstract
The appearance of the first computer means not only the arrival of a new type of revolution, also herald the advent of the technological era. Particularly in the advent of the 21st century, computer technology has been unprecedented development, and the popularity of the network made businesses do nothing without the assistance of computer. For colleges and universities, the automation of the teaching office has been more and more achieved, which could improve the efficiency of the work, standardize the operation of the teaching, and increase scientific.
Based on the analysis of the former Course Scheduling System, the design put forward to a method which is based on a dynamic weighted algorithm (greedy methods), it uses the manual pre-arrangement, automatic timetable and manual adjustment of the three models, and gets the necessary arrangements to some specific technical problems. Concerning the function of system, it achieves basic functions which include access, modify, add, and complex functions like automatically schedule and competence of management. The design uses C/S mode, with Delphi as front development tool, and SQL Server 2003 as backstage database. Though testing, the design can reach the desired effect and achieve the simple function.
 
 Key words: Dynamic weighted algorithm; Automation; C/S mode; Three Levels Course Scheduling Model
