【摘要】 教务管理工作是高校日常管理中的核心工作,是高校的重要职能之一,其管理模式的科学化与规范化、管理手段的信息化与自动化对学校的总体发展有深远的影响。本文根据延安大学“学年学分制”实施的实际情况,分析了C/S、B/S模式各自的优缺点,从软件工程的角度出发,提出了基于C/S、B/S混合模式教务管理系统的设计思路。本文首先给出了教务管理系统的总体设计模式,对系统各功能模块进行了详细的需求分析并采用可视化建模工具Rational Rose对各模块建立了较为完整的UML模型,为系统功能的具体实现提供了清晰的解决方案。其次,对教务管理系统中使用的排课算法进行改进设计,采用遗传算法和贪婪算法共同完成智能排课任务,利用Matlab2009软件对算法进行仿真验证,仿真结果表明算法的有效性;对选课模块中使用的传统抽签算法进行改进设计,采用加权抽签算法来完成选课任务,对选课模块进行负载测试并进一步分析了测试结果,保证选课的合理性、公平性。最后,对教务管理系统的安全性从网络、用户、数据、制度四个方面进行初步分析和研究。
【Abstract】 Educational administration management is the core of universitie’s daily management, also one of the most important functions of colleges and universities. The scientific and standardization of the management model, the informationzation and automation of the management means will have a far-reaching impact on the overall development of a university.This thesis puts forward to the software architecture of the educational administration management system based on the mixed model of C/S and B/S according to the features of Yan’an University’s academic year credit system together with the advantages and disadvantages of C/S and B/S model.Firstly, the thesis makes a detailed demand analysis on each function module of the system, establishing complete UML model for the each module with visualization modeling tools Rational Rose and provides a vivid solution to the realization of the system function.Secondly, the algorithm of curriculum schedule of the educational administration management system and the traditional lot-drawing algorithm of the course selecting module are discussed. By adopting the improved genetic algorithms and greedy algorithm a new hybrid curriculum schedule algorithm is given. Simulation tests are given under Matlab 2009. Simulation results show the efficiency of the schedule algorithm. The traditional lot-drawing course selecting algorithm is improved based on the course weight. Detailed function tests and load tests of the curriculum arrangement module are carried on.Finally, the security of the educational administration management system in the respects of network, user, data and regulation are analyzed and researched;
