Abstract: A system and method for troubleshooting problems in complex systems using multiple knowledgebases comprises a first knowledgebase that has a case-based reasoning engine and knowledge from which a first set of possible solutions can be determined, and a second knowledgebase that has a case-based reasoning engine and knowledge from which a second set of possible solutions can be determined. The first knowledgebase pertains to a first equipment, and the second knowledgebase pertains to a second equipment. The second equipment is a component of the first equipment. A Federation Manager associated with the first knowledgebase transfers a case-based reasoning session between the first and second knowledgebases.

Abstract: According to one aspect, there are systems and methods for component failure-mode surveillance. The system comprises a failure-mode reporting module for managing data derived by engineers in the field about a designed product, and comprises a troubleshooting-sessions database. The failure-mode reporting module is configured to communicate with a product lifecycle management module that stores and manages data about a product design. The failure-mode reporting module uses a component of interest, corresponding to a bill-of-materials in the product lifecycle module, searches a set of troubleshooting sessions based on the component of interest, and provides a report of failure modes experienced in the field for the component of interest. The report may be provided to research and design engineers in order to inform the design of future components.

Abstract: A method and system for reducing the number of cases in a cased based reasoning system that are considered applicable to a current problem for a specific complex apparatus. In addition to a database of previously solved cases, the system has a domain database containing all components that make up a set of apparatus. The system also has a database containing configuration knowledge which defines the components from the domain that are excluded from a specific apparatus. The configuration information is used to filter any cases from consideration as potential solutions if they reference components not in the configuration of the specific apparatus for which the current problem exists. The configuration knowledge is also used to display to the user only the components that make up the specific apparatus for which the current problem exists. The configuration knowledge also includes information on default values for components within the specific apparatus.

Abstract: A method and system for assisting a user in solving a new problem case within a selected domain, such as a complex apparatus.
