基于J2EE标准的网络排课系统的设计与实现

Design and implementation of network course scheduling system based on J2EE

为减轻高等院校排课工作中的人力需求,提高高校教育信息化水平,文中基于J2EE标准实现了网络排课信息管理系统。该系统采用动态规划的思想指导排课,可以有效减小课程冲突,提高排课工作的效率。系统在实现上采用J2EE标准中的Struts2.0和Hibernate框架,设计了信息设置、自动排课、高级查询和用户权限管理等模块,来保证系统功能的完备性。系统在自动排课算法上选择动态规划算法,采用分治的思想将排课问题降解。在排课上采用回溯的原则避免冲突,提高了系统运行的效率。经调试,其运行流畅稳定。此外,系统由于在实现上采用了J2EE标准和模块化设计思想,在整体架构上层次分明,各个层次间耦合性低,极大的方便了后期的维护和功能的拓展。

In order to reduce the manpower demand in the course arrangement of colleges and universities,a network course arrangement information management system is realized based on J2EE.The system adopts the idea of dynamic programming to guide the arrangement of courses,which can effectively reduce the conflict of courses and improve the efficiency of the course arrangement.The system selects dynamic programming algorithm as a course scheduling algorithm.After debugging,the operation is smooth and stable. Due to the adoption of J2EE standard and modular design idea in the implementation,the system has distinct layers on the overall architecture,and the coupling between all levels is low,which greatly facilitates the later maintenance and function expansion.
