摘要
基于对考试方式的发展和考试系统研究现状的认识,阐述了建设B/S模式下的考试系统的重要性。针对集中式考试系统结构存在可扩展性差和负荷集中的弊端,提出了基于Web的分布式考试系统的物理和软件结构,并介绍了各子系统的功能。为使考试系统组卷高效和排卷合理,详述了一种基于网络图和统计理论的智能组卷算法和实现策略。对考试可能出现的多种安全问题,设计了相应的安全机制和保护措施。
Based on the study of test mode and cognition of development ofexamination system, the significance of designing examination
system based on B/S model is presented. In order to solve the problems of poor expansibility and centralized dunction in existing traditional
centralized examination system, physics and software structure of distributed examination system based on web are put forward, and
each sub-function of system is introduced. To form legitimate test paper efficienly, the detailed intelligent algorithms for forming test
paper and realization strategy based on network graph and statistics theory are given, Security mechanism and protection measure of
examination system for some security problems are described too.
