摘要: 文章在介紹飛機變流器維修決策特點的基礎(chǔ)上,給出了一種基于貝葉斯網(wǎng)絡(luò)的變流器故障診斷決策系統(tǒng)的軟件結(jié)構(gòu),并分析了模型建造、知識庫管理、模型推理、診斷決策、實例收集、模型學(xué)習(xí)等模塊的功能和算法,以實現(xiàn)面向不確定性信息時的診斷決策功能。Abstract: Considering the characteristics of the maintenance decision for aircraft power converter, a new type of software structure based on Bayesian network for fault diagnosis is proposed. In the light of the fault diagnosis based on undetermined information, the functions and/or algorithms of several important modules are discussed, such as model building, database managing, model reasoning, diagnosis decision, case collection and model training.
