Abstract
A computer based method for a reusable functional failure test for a specific technical system, e.g., a traffic light system is provided. The method avoids inconsistencies in the functional failure test and reuses items of the respective data structures. Furthermore, the embodiment can identify components or electronic devices that do exceed assumed failure rates and that might be repaired or replaced to keep implementations of the specific technical in the desired failure rate limitations of the analysis, which can be done during the operation of the specific technical system.
Claims15
A computer-based method for a reusable functional failure test for a specific technical system, the method comprising:
- selecting, by a processor of a computing system, from items of a first data structure, at least one component for each technical element of the specific technical system, wherein:
- each component comprises at least one function,
- each function comprises at least one failure mode,
- each failure mode comprises at least one effect,
- each item comprises a unique identifier, and
- identical items are reused;
- instantiating, by the processor, a second data structure based on the selected component for each technical element of the specific technical system;
- executing, by the processor, the reusable functional failure test for the specific technical system by calculating the failure rates for each component;
- and
- testing, by the processor, each component whether the respective components exceed a predefined failure rate.
An apparatus for a reusable functional failure test for a specific technical comprising:
- a selection module, wherein:
- the selection module selects from items of a first data structure at least one component for each technical element of the specific technical system,
- each component comprises at least one function,
- each function comprises at least one failure mode,
- each failure mode comprises at least one effect,
- each item comprises a unique identifier, and
- identical items are reused;
- an instantiation module for instantiating a second data structure based on the selected component for each technical element of the specific technical system, wherein a processor instantiates the respective items;
- an execution module for executing the reusable functional failure test for the specific technical system by calculating the failure rates for each component;
- and
- a test module for testing each component whether the respective components exceeds a predefined failure rate.
