Failure Classification and Analysis for Technical Products

The paper presents an approach to implement a failure classification and associated analyses for production ramp-up. The structural design of the failure classification is described in terms of a faceted classification by design principles to meet the requirements for the indexing of failure cases and the evaluation of specific failure facets. The structural design of the classification is followed by the design of the content of individual failure facets. The failure facets and their contents are used in the analysis. In this paper, the similarity search and the failure priority analysis are developed as functions, as they are particularly relevant in the ramp-up situation. Conceptual model examinations and case studies are carried out for validation.
