Claims17
A method for safety control based on generating an analytical artifact used for investigating a technical system of interest comprised of components having associated machine readable functional descriptions including port definitions and component failure mode descriptions, the method comprising:
- automatically generating, by a processor, the analytical artifact using the machine readable functional descriptions of the components of the technical system, in response to at least one applied system evaluation criterion, wherein the automatically generating the analytical artifact comprises generating a Markov chain by:
- transforming, by the processor, the at least one applied system evaluation criterion into one or more corresponding relevant state patterns at ports forming a system boundary of the system of interest, wherein at least one of the ports is associated with at least one fire sensor that detects fire in a power consumption entity, and by
- generating, by the processor, the Markov chain on the basis of the relevant state patterns and on the basis of the component failure modes of the components of the system of interest;
- and
- disconnecting, by the processor, automatically the components of the technical system depending on an evaluation result of the analytical artifact that is based on input from the at least one port associated with the at least one fire sensor, wherein the technical system comprises the power consumption entity,
- wherein the disconnecting the power consumption entity includes disconnecting the power consumption entity from a power supply grid.
A system for investigating a technical system of interest comprised of components having ports connected to each other via wired or wireless links and having associated machine readable functional descriptions stored in a local or remote memory and comprising port definitions and component failure mode descriptions, the system comprising:
- a processor configured to automatically generate at least one analytical artifact using the machine readable functional descriptions of the components of the technical system, the at least one analytical artifact being processed to analyze, monitor and/or control the system of interest in response to at least one system evaluation criterion input to the processor, wherein the processor is configured to automatically generate the analytical artifact by generating a Markov chain by:
- transforming the at least one applied system evaluation criterion into one or more corresponding relevant state patterns at ports forming a system boundary of the system of interest, wherein at least one of the ports is associated with at least one fire sensor that detects fire in a power consumption entity, and by
- generating the Markov chain on the basis of the relevant state patterns and on the basis of the component failure modes of the components of the system of interest;
- and
- wherein the processor is configured to disconnect automatically the components of the technical system depending on an evaluation result of the at least one analytical artifact that is based on input from the at least one port associated with the at least one fire sensor, wherein the technical system comprises the power consumption entity,
- wherein the disconnecting the power consumption entity includes disconnecting the power consumption entity from a power supply grid.
