A monitoring production of a technical apparatus in a secure and reliable manner is provided. This monitoring is achieved using encapsulation of a first distributed ledger into a second distributed ledger.

Hierarchical distributed ledger

At least one embodiment of the present invention relates to supporting a safety-oriented system, with the safety-oriented system including safety-critical software components and non-safety-critical software components. In this method, a possibility of a safety-critical software component and a non-safety-critical software component influencing each other is identified and a set of technical measures for preventing the possibility of influencing is defined. In this way, an absence of feedback from non-safety-critical software components to safety-critical software components is both verified and also ensured by at least one embodiment of the present invention.

Method for supporting a safety-oriented system

Disclosed is a full error description for a technical system which is described by a system description which can be processed by a computer and stored. The system description contains information on elements available in system and information on the links therebetween. An element error description is determined for each element taken into consideration, using a stored error description which is respectively associated with a reference element. At least one part of the reference elements is grouped into a reference element group and a group error description is determined for the reference elements of a reference element group using a stored group error description which is respectively associated with a reference element group, enabling possible errors of the reference elements of the reference element group to be described. A full error description is determined from the element error descriptions and the group error descriptions, taking into account information on element links.

Method and device for determining a full error description for at least on part of a technical system computer program element and computer-readable storage medium

The faults are described using a fault description which comprises data which have been determined using failure modes and effects analysis. The fault description is extended by information regarding the dependency of possible faults and the frequency of occurrence of said faults. The extended fault description is used to ascertain, for a prescribed fault event, the fault tree and the frequency of occurrence of the fault event.
