A System for Failure Response Advice Based on Diagnosed Failures and Their Effect on Planned Activities

The role of Failure Response Advisor (FRAd) is to identify the relevant information and to use it to compute the severity of faults and repair times. Advanced Caution and Warning System (ACAWS) modules for diagnosis and system effects identify faults and impacts and deliver that information to the Planner. The Planner gathers information about activities from an Activity Dictionary. The role of the planner in FRAd is to detect violations in the resources required to perform the set of planned activities. This information includes what resources are needed for given activities to be performed. The Planner correlates fault and impact information with its effect on activities to be performed and delivers the correlated information (Activity Effects) to the Reasoner. The Activity Information Repository, contains the activity information required by the Activity Dictionary and additional timing information required by the Reasoner. Additional information on faults is contained in a Fault Table and is delivered, as needed, to the Reasoner that computes fault severity, repair timing suggestions, and provides the advice to be published on the User Interface. The role of the Reasoner is to compute both proposed timing information for repair activities and to provide a value of Severity based on the number and criticality of the activities blocked by given faults and the functional failure of all impacted components. The concept of Severity is quantitative, based on the number and Criticality of activities blocked by the failure.
