    • A method and system for comparing and merging fault models which are derived from different data sources. Two or more fault models are first represented as bipartite weighted graphs, which define correlations between failure modes and symptoms. The nodes of the graphs are compared to find failure modes and symptoms which are the same even though the specific terminology may be different. A graph matching method is then used to compare the graphs and determine which failure mode and symptom correlations are common between them. Finally, smoothing techniques and domain expert knowledge are used to merge and update the fault models, producing an integrated fault model which can be used by onboard vehicle systems, service facilities, and others.
    • 用于比较和合并来自不同数据源的故障模型的方法和系统。 首先将两个或更多个故障模型表示为二分加权图,其定义故障模式和症状之间的相关性。 将图的节点进行比较以找出相同的故障模式和症状,即使特定的术语可能不同。 然后使用图匹配方法来比较图,并确定它们之间的故障模式和症状相关性。 最后,使用平滑技术和领域专家知识来合并和更新故障模型,生成可由车载系统,服务设施等使用的集成故障模型​​。
