摘　　要：针对传统纸质考试存在的弊端,结合当前的信息化技术和智能算法,提出一种基于UML面向对象的在线考试系统。在系统设计过程中,笔者首先对在线考试系统设计需求进行分析,并在此基础上引入UML面向对象建模技术,对在线考试系统的使用角色及用例图进行设计。然后分别从系统整体架构、功能模块、数据库等进行了详细的设计,并重点针对在线考试中对组卷的智能化需求,在构建组卷目标函数的基础上,运用混合粒子群算法对目标函数进行求解,以得到最优解,最终提升在线考试组卷的精度。最后,给出了部分在线考试系统实现的界面,以此希望通过本文的构建,为当前计算机技术的应用提供新的案例。In view of the disadvantages of traditional paper examination, an online examination system based on UML object oriented is proposed in combination with the current information technology and intelligent algorithms. In the process of system design, the author first analyzes the design requirements of the online examination system, and on this basis,introduces the UML object oriented modeling technology to design the use role and use case diagram of the online examination system. Then the detailed design is carried out from the whole system architecture, function module, database and so on. On the basis of building the target function of the group, the mixed particle swarm optimization algorithm is used to solve the target function, and the optimal solution is obtained. Finally, the online examination group is promoted. The accuracy of the volume. Finally, the interface of some online examination system is given, hoping to provide a new case for the application of computer technology through the construction of this paper.
