摘要： A system and method for determining the state of health of a vehicle based on a determination of factored miles. The method includes collecting data from a group of vehicle of a common model type as aggregate data and data from a particular vehicle as individual data. The aggregate data and the individual data are used to determine a percent degradation of sub-systems and components on the vehicle, and an overall percent degradation is determined by accumulating the percent degradation for the sub-systems and components. The accumulated percent degradation is then used to determine a factored miles value that is an indication of the state of health of the vehicle based on vehicle driving conditions and other considerations. The factored miles can then be used by various business models to determine the value of a vehicle.

摘要： A system and method for enhancing vehicle diagnostic and prognostic algorithms and improving vehicle maintenance practices. The method includes collecting data from vehicle components, sub-systems and systems, and storing the collected data in a database. The collected and stored data can be from multiple sources for similar vehicles or similar components and can include various types of trouble codes and labor codes as well as other information, such as operational data and physics of failure data, which are fused together. The method generates classes for different vehicle components, sub-systems and systems, and builds feature extractors for each class using data mining techniques of the data stored in the database. The method also generates classifiers that classify the features for each class. The feature extractors and feature classifiers are used to determine when a fault condition has occurred for a vehicle component, sub-system or system.

摘要： A method and system for developing reliability models from unstructured text documents, such as text verbatim descriptions from service technicians. An ontology, or data model, and heuristic rules are used to identify and extract failure modes and parts from the text verbatim comments associated with specific labor codes from service events. Like-meaning but differently-worded terms are then merged using text similarity scoring techniques. The resultant failure modes are used to create enhanced reliability models, where component reliability is predicted in terms of individual failure modes instead of aggregated for the component. The enhanced reliability models provide improved reliability prediction for the component, and also provides insight into aspects of the component design which can be improved in the future.

摘要： A method for temporal trend detection employing non-parametric techniques. A set of discrete data is provided and a rank is assigned to the data based on both sensitivity and severity of the data. The method statistically ranks the ranked data by categorizing the data in bins defined by an average positional ranking that identifies the severity of the data for each sensitivity category provided by a bin. The method then clusters the statistically ranked data that has been categorized by average positional ranking so as to detect changes in the data. Clustering the statistically ranked data can include using a multi-nominal hypothesis testing procedure. The method then identifies trends in the data based on the detected changes.
