Abstract

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．

Key words： ship auxiliary boiler; World Wide Web; expert system; evaluation algorithm; membership function
