摘要
随着计算机技术的迅猛发展,网络应用范围的不断扩大,教育领域与计算机
技术的紧密结合,无纸化考试系统已成为深化教学改革,推进教学创新,提高教
务效率的重要平台,但大多数同类系统的题库通用性不足,智能组卷策略有待提
高。
本文首先介绍了题库建设的基本理论、相关技术和核心问题,然后提出题库
管理系统的需求分析,明确了系统的总体结构,并对数据库的概念设计、逻辑设
计、以及数据的实体设计进行详细的研究。题库管理系统的核心是组卷算法,本
文在自动组卷方面,主要研究了随机算法和遗传算法在组卷系统上的应用,提出
了先进行多次随机算法筛选再进行遗传算法的自动组卷策略。最后使用和
SQL Server 2000 开发出了题库管理与组卷系统,该系统的组卷效率和质量都达到
了预期的目标。
本系统的应用增强了教学效果,实现了资源重用,减少了教师工作量,提高
了学生学习的积极性,降低了教育经费,能够满足本校的在线考试要求。

Abstract
Along with the rapid development puter technology and the
unceasingly expand work application, the education puter
bine closely. Paperless examination system has e an
important platform of deepening teaching reform, promoting teaching innovation,
and improving the administration efficiency. However, most of the item pools do
not adapt to many circumstances and the intelligent strategy of forming the paper
needs to be improved.
This paper introduces the basic theories, related technologies and core issues
of item pool construction firstly, put forward the requirements analysis of
management system of the item bank , makes the general structure of the system
clear, and conducts detailed study into the concept and logical design of the
database, as well as the entity design of data. The core of the pool management
system is calculation of forming the paper. On automa ticaly form the paper, this
paper mainly discussed the application of random algorithm and ic
algorithm in form the paper, and holds forth the idea of carrying on several
random algorithm screening first, then the automatically paper of
ic algorithm. Finally, by using and SQL Server 2000, the item pool
management and form the paper system are produced. The efficiency and quality
of this system have both reached the expected goal.
The application of this system strengthens the teaching effect, achieves the
resource r
