摘要
面向仿真系统的自动测评通常有基于操作结果和基于操作序列两种方式。基于操作序列的测评方式虽然复杂,但能够全面、客观地反映考生实践操作技能。本文重点介绍操作序列通用框架的表示问题,在此基础上,建立基于专家系统的操作测评模型和实操考核自动评分流程,最后给出自动测评关键技术在航海仪器测评系统中的实际应用,实现了评分结果的相对客观、公正,大大提高了实操考核的工作效率。
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.
