规划识别在船用柴油机故障预测中的应用研究

Applied research of plan recognition in fault prediction for marine diesel engine

将规划识别理论应用到船用柴油机故障预测领域,同时建立了基于规划知识图的柴油机燃油系统故障预测规划模型。该模型对原有规划知识图进行了改进,与之前知识图相比新知识图在抽象节点中加入了支持度,使知识图处理规划的识别可以根据先验知识而合理地加以改变。实验表明改进后的模型可以有效地提高预测准确度。

Shall be bought forth that plan recognition theory would be put into practice in the field of marine diesel engine fault prediction. Having been constructed as well, the diesel engine fuel-burning system model is based on plan knowledge graph. The model mentioned above improved the original graph. Compared with the old graph, the new one introduced supporting degree into abstract node, so the recognized plan are changed reasonably according to practical experience. Finally the experimental results show modified model can effectively increase prediction accuracy.
