Design And Implementation Of On-Board Training Evaluation System Based On Expert System

With the continuous development of modern ocean industry, how to cultivate high quality sailors efficiently has become an urgent problem. Training in a real ship not only costs highly without all extreme situations, but also has no guarantee of safety. With the rapid development and mature of computer simulation technology, simulation software of training system is designed to train the sailors. The advantages of training simulation system include good portability, cost savings, comprehensive training process, efficient, etc.A ship training simulation system mainly includes four parts, the trainer part, the trainee part, the server part and the simulation model part. The trainer part is studied in detail. A perfect and reliable training evaluation system is introduced in this thesis. The training evaluation system is used to grade and evaluate automatically. The main work is done as follows:First, MFC(Microsoft Foundation Classes) is used to design the interface of trainer part, and it is guaranteed that the interface is friendly and operates easily. The interface consists of coach login interface, training management interface, data management interface and evaluation interface.Second, expert system is used to guide students before practice and evaluate after practice. In addition, questions raised by students will be answered. If the simulation system is abnormal, the expert system will diagnose and remind in time.Third, the score is given by the evaluation system after training. Firstly, score item is determined. Secondly, the weight of each item is made. Finally the final score is calculated by weighting each item.Forth, data is processed based on SQLite embedded database, and the main operations include the data storage, management and query.
