【摘要】 本系统是应各种考试机构进行在线考试和在线练习需要，可实现题库管理、自动和手动组卷、在线考试或练习、自动阅卷评卷等功能。并将以人工智能原理为基础的遗传算法应用于智能组卷，既实现了系统的智能化，减少了偶然性和随机性，又能满足用户的分布式计算要求。 本系统采用B／S结构，即采用浏览器一Web服务器一数据库服务器三层结构，是对传统的C／S结构的改进。在客户机上无需安装考试应用程序，只需要有浏览器即可。开发环境与应用环境分离，提高了系统的可扩展性、安全性和可重用性。数据库结构的改变对客户端不产生连锁影响，提高了系统的维护效率。在服务器端，系统平台采用Windows XP，安全性好、运行稳定、管理容易。数据库平台采用Microsoft Office Access 2003，使用方便、可伸缩性好、与相关软件集成程度高。系统采用ASP技术实现用户界面层的设计，可移植性好、代码执行效率高、与数据库的连接方便。 本系统采用最高管理员、一般管理员、教师、考生四级授权方式，提高了系统的安全性。管理员负责系统的维护，可以增加、删除能对题库进行操作的教师以及学生用户。教师仅可以添加和批改授权科目的试卷和题目。考生可以利用考试系统进行答卷，并对成绩进行查询。更多还原

【Abstract】 This system is designed to suit the need of all kinds of examination for exam and exercise on line. The system can carry out the management of warehouse for test paper, automatic and manual paper organization, test and practice on line, automatic assessment and so on. The intelligent paper organization will use the genetic algorithms based on artificial intelligence principles. The system not only carry out intelligentize and decrease chanciness and randomicity, but also can meet the user need of distributed account.The system is based on B/S model—a three tier model of Browser/Web Server/Database Server derived from traditional C/S model. Only a browser instead of a test application program is needed to be installed in client machine. Development environment is separated from application environment to improve the scalability, security and reusability. The change to the database structure can not influence client so that the efficiency of system maintenance can be improved. The operating system in server machine is Windows XP and it has features such as good security, stable function and easy management. Microsoft Office Access 2003 is used as database development platform and it has features such as convenient use, good scalability,high level of integration with relative software. ASP technology is adopted to design user interface and it has features such as high portable feature, high efficiency of code execution and convenient connection with database .The system provides good security in the fashion of four-tier authorized system including top administrator, generic administrator teacher and student. The administrator is responsible for the system maintenance and can do manipulation with the system such as adding or deleting content in the test question database. Teacher is responsible for managing test question database, producing test papers, evaluating test integratedly and so on. Examinees can use the test system to do test and query grade.更多还原
