Method and apparatus for providing a safe operation of a technical system

A computing system comprising a computer readable storage medium for providing a safe operation of a technical system comprising a plurality of system components, comprising:

• a) a modelling unit of the computing system for providing a safety analysis model of the technical system matured by knowledge about former implementations of the respective system components in different contexts;
• b) whereby dependencies of system components dependencies are modelled by connecting inports with outports of the respective system components or by connecting outports with inports of the respective system components;
• c) whereby the inports and/or outports of each system component are associated with input failure modes and/or output failure modes of the respective system component;
• d) an analysis unit of the computing system for automatically uncovering inconsistencies caused by at least one new system component to be integrated in connection with at least another downstream system component or upstream system component of an existing technical system, whereby the input failures modes and/or output failure modes of the system component to be integrated carries the knowledge from another implementation into a new context;
• e) wherein for a system component to be integrated into the existing technical system, the failure modes which require integration and unconnected failure modes of the system component to be integrated are identified using a previously defined set forward which identifies unconnected failure modes of the system component to be integrated, whereby existing knowledge of the system component to be integrated is transferred into a new technical system where the component to be integrated is reused;
• f) wherein for the system component to be integrated into the existing technical system, unconnected failure modes of the system component to be integrated are identified using a previously defined set backward which contains unconnected failure modes of the existing system components where the system component is to be integrated;
• g) whereby existing knowledge of the existing system is transferred back to the reused system component of the technical system, whereby existing instances of the reused system component in other systems or implementations are reviewed.
