Operation method and operation device of failure detection and classification model
An operation method and an operation device of a failure detection and classification (FDC) model are provided. The operation method of the FDC model includes the following steps. A plurality of raw traces are continuously obtained. If the raw traces have started to be changed from the first waveform to the second waveform, whether at least N pieces in the race traces have been changed to the second waveform is determined. If at least N pieces in the raw traces have been changed to the second waveform, the raw traces which have been changed to the second waveform are automatically segmented to obtain several windows. An algorithm is automatically set for each of the windows. Through each of the algorithms, an indicator of each of the windows is obtained. The FDC model is retrained based on these indicators.

COMPUTER-IMPLEMENTED METHOD AND DEVICE FOR RESOLVING CLOSED LOOPS IN AUTOMATIC FAULT TREE ANALYSIS OF A MULTI-COMPONENT SYSTEM
A computer-implemented method and device for resolving closed loops in automatic fault tree analysis of a multi-component system is provided. Also provided is a method for resolving closed loops in automatic fault tree analysis of a multi-component system, the closed loops corresponding, for example, to closed-loop control circuitry of a multi-component device. The closed loops are first identified in a top-down approach within failure propagation paths. Next, the loops are resolved by setting each loop interconnection to Boolean TRUE, adjusting the fault tree in a specific way and finally setting each loop interconnection to Boolean FALSE. Embodiments of the invention are relevant for analyzing safety-critical systems. However, the present concepts are not limited to these applications and may be applied to general use cases where fault tree analysis is applicable. The proposed solution advantageously provides a method that features linear complexity.

Generating a fault tree
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.
