摘要
本文结合船舶控制系统的特点,提出了船舶控制系统故障诊断专家系统的组成、结构、知识的表达方法,诊断的逻辑推型。特别提出了基于元件的可维性系数和故障的可靠性值的模糊推理方法,在专家系统的智能化方面,讨论了利用创造性思维推理对故障诊断模型的修改及利用指数修匀法对可能性值的修正方法。
How to build a fault diagnosis expert system for a ship control system is proposed in this paper. Configuration of expert system considering the distinguished features of ship control systems is discussed. Knowledge representation model and diagnosis logical inference mechanism are studied. Special attention is paid on fussy inference based on rnaintalnable factor and trouble probability of parts. Intellectualized expert system ernploying creative thinking inference to improve the diagnosis model and using exponent smoothing method to correct the trouble probability is also studied
