摘要： A method, computer program product, and system that discards unneeded elements when generating a fault tree of an object to be analyzed. Configuration information identifies a plurality of functional blocks comprised by the object and a plurality of signal lines that connect the functional blocks in logical relationships. Exclusion target information identifies a signal line that may be excluded from the plurality of signal lines without loss of information or a functional block that may be excluded from the plurality of functional blocks without loss of information. Exclusion of a block or signal line may be determined by detecting a redundant functional block or by detecting a circular signal path traversed by two or more signal lines. The generated fault tree omits the excluded block or signal line and identifies the existence of a redundant block or of a circular signal path.

摘要： A method is provided for updating a fault tree used in diagnosis of a condition of a machine. The fault tree is a sequence of test modules. Each of the test modules is assigned a confidence score indicating the likelihood that the test module will lead to a diagnosis. The method comprising the steps of obtaining service data from a plurality of service occasions for like machines, revising the confidence score for at least one test module in the fault tree based on the service data; and revising the sequence of the test modules in the fault tree based on the revised confidence score(s). The sequence is revised such that the most likely modules to result in a diagnosis are listed first, and the least likely ones are listed last. The re-ordering is based on feedback from actual service instances in the field, and thus is more likely to reflect real-world conditions. The result is that service technicians using the revised fault trees work more efficiently, at least on a statistical basis.

摘要： A method and apparatus for detecting and analyzing errors in a communications system is described. The method employs expert system techniques to isolate failures to specific field replaceable units and attempts to restore the failing unit to service, if the system will not be adversely affected, by removing it from service, resetting the resource and returning it to service if it passes retesting. The expert system techniques include detailed decision trees designed for each resource in the system. The decision trees also filter extraneous sources of errors from affecting the error analysis results.

摘要： A System and a method are provided for the monitoring of a control process in a process plant such as a power generation plant. The process plant contains a plurality of plant items to be controlled, such as valves, pumps, turbines and so forth. At least some of these have sensors attached to them which output a digital (binary) or analog signal indicative of the status of that plant item. Many plant items also have control actuators for shutting and opening the valve, for example. The plant item sensor outputs are connected to a network and a control algorithm representing the control logic of the process plant processes the sensor outputs. The output of one of a plurality of control functions forming the control algorithm is selected to begin a fault tracing procedure. The control logic forming the control algorithm is visually displayed on a computer monitor. The selected control function output is traced back to its source via the control algorithm shown on the computer monitor to identify the root cause of a fault.

摘要： An optimization method is used in a real-time diagnostic system that monitors alarm sources and detects possible sources of failure in an industrial process. When the diagnostic system detects one or more alarms, it determines which components are likely sources of failure. The system determines the level of criticality of certain other, currently off-line, alarms sources and schedules the off-line alarms for evaluation according to their levels of criticality. The system refines its analysis of likely sources of failure by evaluating the status of the previously off-line alarm sources Those previously off-line alarm sources are added to the grouping of possible sources of failure prior to repeating the evaluation process. The evaluation process is repeated, with the analysis of likely causes of failure being continually refined.
