Heuristische Echtzeit-Fehlererkennung bei Deformationsmessungen wahrend des Tunnelvortriebs

摘要

The outlined Certainty Factor method, originally developed in the research area of Knowledge Based Systems, represents an ad hoc concept of quantitative, uncertain reasoning. It is based on numerical values, so called Certainty Factors, expressing the certainty of statements (e.g. about the existence of errors in monitoring data) and an intuitive algorithm processing them to an output certainty (e.g. of a possible error cause). Therefore it allows the representation of and reasoning from the uncertain expert knowledge of a domain. This paper discusses an application of this method for error analysis of displacement data in tunnelling.
