Design And Implementation Of Online Exam Management System Based On Genetic Algorithm

With the changes of the times and the advancement of technology,the field of education is gradually being penetrated by Internet-related technologies.For students,there is also a gradual transition from on-site paper-written examination papers to computerassisted examinations in information.The online examination management system has gradually become an important link that cannot be ignored in the education field by virtue of its unique advantages.With the blessing of Internet-related technologies,the online examination method breaks through the constraints of traditional examinations in all aspects,allowing teachers to easily compose examination papers,organize examinations,review examination papers,and analyze results.Students can also take examinations on the Internet without being affected.The influence of location has simplified a series of complicated procedures of traditional examinations,promoted the standardization of examinations,and effectively improved the work and learning efficiency of teachers and students.In the research of the examination management system,through the targeted analysis and improvement of the problems existing in the current market products,such as the substandard quality of the question bank,the inefficient test paper composition,the unqualified test paper standard,and the unreasonable distribution of knowledge points on the test paper.Gives its basic functional requirements and extended functional requirements.Then,using UML modeling language as a carrier,design the use case diagram of the main functional modules of the system,and establish its functional structure in the form of flowcharts and sequence diagrams.In the construction of test paper model,genetic algorithm is used as the core test paper algorithm of the system,and the genetic operation of test paper model is improved,designed and implemented.In addition,in order to make the system more complete and meet the expected goals and requirements,it has good maintainability and scalability,the system has been analyzed in detail from the overall and functional dimensions,and based on the functional requirements and quality requirements,the implementation details of each functional module and the display effect of the related interface are presented.Finally,the corresponding test cases are designed to conduct comprehensive tests to solve the problems in the test process,so as to ensure that the system functions can meet the expected goals and requirements.The online examination management system provides a feasible solution for the networked management of examinations,which not only makes up for the shortcomings of traditional examinations,but also promotes the fairness and impartiality of examinations to a certain extent,and has a positive effect on the improvement of teaching quality.Actively promote the role.
