The Research And Design To The Power Spply Company Testing System Based On The Improved Adaptive Genetic Algorithm

With the increasingly high demand for the development of network technology and technical personnel’s knowledge and ability level, skilled practical talents more and more attention to the skills certification exam, the influence is also growing, occupation qualification certificate obtained has become one of the necessary for many enterprises and institutions of the certificate. To participate in the examination of the number has increased year by year for each skill identification station is responsible for the examination of the registration personnel brought considerable workload. To develop a set of suitable for the examination of the application system is very important.As a result of the online examination system, test paper algorithm is the main key technology, the paper intelligent generating system is how to deal with the optimization of the multi-objective, under the constraints. The traditional ways, such as random choosing and backtracking, cannot deal with this problem properly. They bring a lot of problems, such as the efficiency of the generating time and the success rate of the paper generating. To deal with these problems, the paper is discussed an improved genetic algorithm, to satisfy the user’s demand. In view of the traditional genetic algorithm is easy " premature" phenomenon, the use of dynamic parameter adaptive adjustment method and the elite reservation strategy to improve, realize the adaptive genetic algorithm for online test scheme.This paper introduces the design principle of the system, syste m architecture and functional structure of the system, and gives the system module structure. The detailed design stage, the user management, examination management and examination management system as an example, introduces the class design and timing dia gram and system design, the function relation is described by the UML static structure diagram and sequence diagram; database design, system data base model described by E R diagram, and introduces the database table the design of the system. In the implementation phase of the system, describes the system function, and demonstrate the system function realization code and realize the activity diagram; system test phase introduced the system test purpose, process and results. Finally, the paper summarizes the work.The system can meet the power supply company skills certification exam registration requirements, can effectively alleviate the labor intensity of the test personnel during the registration period, reduce the administrators and staff workload, save a lot of manpower, material and financial resources, while strengthening the data accuracy and reliability, the skills certification exam registration, network standardization, systematization, program.
