摘　　要：针对船舶辅锅炉实物系统操作环境风险高、维护费用大以及其在操作考试和自动评估方面功能不足等限制因素,提出一种基于Web的船舶辅锅炉自动评估系统.该系统采用Web技术,解决实物系统弊端的同时为学员随时随地学习提供了可能性.试题导入机制的自动出题、随机组卷及动态改变操作初始状态的功能为考试带来了公平性和灵活性,提出一种基于专家系统评分规则的评估算法并应用于仿真系统中;采用变量评判数据库来存储每道题目的评分项情况,并选用合适的隶属函数计算变量的隶属度;操作结束时自动打分并提供可查询的操作结果反馈.实例操作结果与专家打分一致,验证了该算法的可行性.Due to limitations of operational risk and maintenance costs as well as the deficiency of operation examination and automatic evaluation in a ship auxiliary boiler system,an automatic assessment system based on Web was proposed.With the technology of Web,the system enhance the flexibility of students＇ independent study. The dynamic change of initial state and drawing questions automatically brings flexibility for the exam. An evaluation algorithm based on expert system assessment rules was proposed and applied in this simulation system. The rating items for each question was stored in variable evaluation database. A membership function was chosen to calculate the membership degree for each variable during the evaluation. The score was given automatically at the end of the examination and provided actionable result feedback. The fact that the evaluation result is consistent with the scores given by the expert system show that the feasibility of the algorithm is well verified.
