Design And Implement Of Ordnance Repairmen Aided Training & Examination System

Along with the updating of the Chinese People's Liberation Army's weapons and equipment, it is an important problem that how to train a high quality talented person troop for ordnance repair. This paper is focused on training and quiz which is the core problem in ordnance repairmen teaching to carry out research and implement of this system.In training, students often encounter many problems that can't be solved in time. On the other hand, the teachers have accumulated many pictures and videos material about ordnance equipment maintenance, but because there is no a good application platform, the material can't be applied to training. Test is an important approach to check up the quality of ordnance repairmen teaching. In the past, teachers compose the exam paper by hand, and there are many human factors and random factors that often make the paper be so unreasonable that the exam can't achieve fair and impartial effect. Furthermore, traditional exam paper can't use multimedia material such as sound and video, the representation of test questions is monotonous.In order to solve the above problems, after the system application background and function demand are analyzed in detail, the subsystem of ordnance repairmen aided training is proposed, which uses binary decision tree to describe fault knowledge and human-computer interface method to implement. By using this system, students can master detection procedures and maintenance method of ordnance equipment faults. In order to solve the problems in artificial composing exam paper, this paper adopts Genetic Algorithms to compose exam paper, which improves the efficiency and achieves the automation and intelligence in the exam paper composition. The teacher can modify the exam questions in the composed paper, so that the teacher can make the paper correspond to teaching practice. As this system can test online, exam paper can use multimedia material which makes the representation of the paper be colorful.This paper introduces some relative theories of system development and architecture, describes the design of failure knowledge base and test questions base and presents the application of Genetic Algorithms in exam paper composition. Finally, this paper gives the implementation process of the system in detail.
