    • A method of integrating case based reasoning data and FMECA data for product life cycle support. The method comprises creating an access path to case based data using a FMECA classification. The creating includes receiving a case based record including heading data. The heading data includes data elements and the data elements are correlated with data fields in a FMECA database. The FMECA database is searched for an entry that includes one or more of the data elements. The creating further includes determining if the entry should include a reference to the case based record. A new pointer to the case based record is inserted if the determining results in finding that the entry should include a reference to the case based record. The method for integrating case based reasoning data and FMECA data further comprises receiving a request from a user to access the case based data. The case based data is accessed via the FMECA database using the access path in response to the request.
    • 一种将基于案例的推理数据和FMECA数据集成在产品生命周期支持中的方法。 该方法包括使用FMECA分类创建基于病例的数据的访问路径。 创建包括接收包括标题数据的基于案例的记录。 标题数据包括数据元素,数据元素与FMECA数据库中的数据字段相关。 搜索FMECA数据库以包含一个或多个数据元素的条目。 创建还包括确定条目是否应包括对基于案例的记录的引用。 如果确定结果发现该条目应包括对基于案例的记录的引用,则插入基于案例的记录的新指针。 用于集成基于案例的推理数据和FMECA数据的方法还包括从用户接收访问基于病例的数据的请求。 通过使用访问路径响应请求,通过FMECA数据库访问基于案例的数据。

    • A locomotive for model-based incipient failure detection includes at least one replaceable unit and at least one sensor to generate signals representative of current engine conditions related to the at least one replaceable unit. A controller includes an embedded replaceable unit model algorithm. Current operating conditions and ambient conditions are utilized within the algorithm to generate a model-based predicted value for the at least one sensor. The controller compares the at least one sensor signals to the model-based predicted values for calculating deviations therebetween and detecting incipient failure of the at least one replaceable unit.
    • 一种用于基于模型的初始故障检测的机车包括至少一个可更换单元和至少一个传感器,用于产生代表与所述至少一个可更换单元相关的当前发动机状况的信号。 控制器包括嵌入式可更换单元模型算法。 在该算法中利用当前操作条件和环境条件来生成至少一个传感器的基于模型的预测值。 控制器将至少一个传感器信号与基于模型的预测值进行比较,以计算它们之间的偏差并检测至少一个可更换单元的初始故障。
