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

Computer-supported prognosis of the reliability of a technical system, which comprises a processor on which programs are run determines an analysis and/or projection prognosis figure, which gives the expected complexity for generation of the programs in a metric for the analysis and/or the projection. An implementation figure is determined from the analysis and/or projection prognosis figure which gives the expected complexity for production of the programs in a metric for the implementation. Finally a reliability prognosis figure is determined from the implementation prognosis figure which gives the expected reliability of the programs.
