Abstract: For the automatic evaluation facing simulation system, there are two modes, one is based on operation results and the other is based on operation sequence. The assessment mode based on operation sequence is complex, but it can reflect the practical operation skills of examinee comprehensively and objectively. The paper firstly emphasizes the framework’s general representation of operation sequence. Then on these bases, the paper establishes an operation evaluation model and automatic rating process of operational examination based on expert system. Lastly, it gives the practical applications of the key technologies of automatic evaluation in the evaluation system of navigation instruments, realizes the relatively objective and fair grading result, improves the efficiency of operational examination greatly.

Key words: operation sequence, automatic evaluation, expert system
