Abstract


With the growing maturity of computer network technology and artificial intelligence techniques, as well as the increasing demand of computer-assisted instruction, computer online exam to the rapid development of this new mode of examination. Computer online exam system, the key part of the intelligent combination of papers module construction and design, that is, how to select teaching mission and goals of the questions in the test database target exam papers. For intelligent combination of papers module as well as the study of online examination system has become the focus of research in the field of computer science and applied pedagogy and hot spots. The intelligent combination of papers module key is the establishment of the corresponding mathematical model, by its very nature is solving multi-objective build one for papers evaluation parameters optimization problem. First of all, in the traditional mathematical model basis of detailed analysis and research, pointed out that the lack of traditional mathematical models in the build process, given the improved optimization model. The improved model through the use of qualitative and quantitative analysis method of combining the traditional multi-objective optimization problem into a single-objective optimization problem improved. Secondly, in order to improve the efficiency of solving optimization problems, an improved particle swarm optimization algorithm is introduced. Improved particle swarm optimization algorithm, compared with the traditional method, has more to jump out of the local optimal solution, thereby enhancing the ability to search the global optimum solution. After using the modeling idea Struts MVC-based architecture developed computer IT training exam (Computer Information Technology Training Examination-CITTE) system, the system is a comprehensive set of network test system set exam Candidates library, papers database management, network test, electronic scoring, results processing in one, realize Examination, test automation and paperless. The system uses B / S mode, test management and database management, browser / server mode, the server browser exams. The system CITTE the development environment for Windows XP, and development tools for Eclipse is an open source, Java-based extensible development platform. CITTE rigorous system structure, easy to operate, all exam papers organization as a unified standard, easy-exam management. Finally, this CITTE performance experimental verification, the final test results show that CITTE design idea is feasible and practical application is effective. CITTE improve the degree of standardization and normalization of the exam, and to increase the authority and reliability of the exam.
