Ontology-based Representation of Time Dependent Uncertainty Information for Parametric Product Data Models

摘要

The lack of information about uncertain conditions in manufacturing and the behaviour of load carrying systems still lead to fatal design decisions. Semantic technologies provide the necessary capabilities to link information from different domains along the product lifecycle and enable engineers to cope with uncertainty. This paper presents an overview of existing literature in the fields of semantics in CAD and PLM. We identify future research challenges and present our concept for the integration of uncertainty information in parametric CAD models.
