Online Examination System Design And Implementation Of Si Chuan Water Conservancy Vocational And Technical College

Digital Campus Based on Online examination platform management subsystem with automatic examination of the volume and the two planned automaticscheduling feature that allows the management of school exams to achieve systematic unified management,campusworkers integrated security management efficient and convenient working environment. School examination consists principally of the volume and the exhaust test.Previous classroom teachers out and examination schedules are used in a manual manner,consuming laborious and error-prone.Examination Management subsystem utilization.NET and SQL Server database technology, the use of C #. NET programming,implementation.Another test management subsystem also use Remoting technology to implement Layer C/S structure to meet current campus digital information,intelligence needs. System development time to follow industry standards, try to make the system has good interactive interface.Test management subsystem will automatically be applied to the genetic algorithm and examination schedules,the use of genetic algorithms for automatic extraction questions,automatic scheduling exam time and place. Including how to use language to describe the genetic evolution of computer, how to use genetic algorithms to achieve the volume and examination schedules, how to roll out automatic and automatic test scheduling genetic algorithm optimization, these are the focus of the study as well as the system difficult.To combine a complete papers need to consider questions of attribution of knowledge level questions,cognitive categories, degree of difficulty, discrimination, answer time, reference scores, etc. These attributes. Examination Management subsystem mainly used on Algorithmic difficulty factor this property. To organize a proper exam schedule needs to meet:(1) the same professional grades one time only for one of the Examination(2) examination must be the same subject at the same time(3) Examination of seats must be greater than the number of students taking the test(4) each course must be conducted and only one examination, these hard conditions. Since exam scheduling problem is a huge and complex issue, so the actual settlement process, the exam scheduling problem into the examination room examination timetabling arrangements and scheduling problems. These two issues are mutually independent but interrelated.On the one hand, since the two issues as against a different direction, so the design using two algorithms(examination timetable arrangements exam scheduling algorithms and algorithms), respectively, on the two issues were solved step by step; On the other hand, the examination timetable arrangements should take into account the problem solving scheduling problems in the examination room examination room capacity size,examination scheduling problem solving examination timetable arrangements to use the solution as part of algorithm parameters. Such a solution algorithm for solving ideas to reduce the pressure from the objective to reduce the difficulty of programming.In the use of genetic algorithms for achieving specific crossover strategy,mutation strategy and selection policy.The examination management subsystem for functional tests found the check function and protect the elite strategy resulting from a mating advantage of individual types of pool fully occupy the phenomenon,so take a dynamic setting may be individual variation in the number and the number of mutated genes factor the value of the design, the algorithm has been improved,effectively avoid the above phenomenon.The algorithm continues to experiment,algorithms for the problem of high failure rate, using the accelerated death and execution of multiple computing strategy, the algorithm has been improved to increase the chances of success of the algorithm after several pairs algorithm,for the same test data,the algorithm is able to give a satisfactory result of a higher degree. Algorithm is relatively successful completion of the desired goal.There are many aspects of test management subsystem needs to be improved,for example,the original system functions can be further improved algorithms( algorithms improve computing speed,the system functions to extend( add other modules function),the system interface landscaping and so on.From a macro point of view, such a test management subsystem campus followed the birth of the pace of development of information management,in line with comprehensive information on campus development.
