Premλp: knowledge driven design of materials and engineering process

摘要: In this paper, we present the knowledge engineering aspects of an IT infrastructure for a Platform for Realization of Engineered Materials and Products (PREMΛP). PREMΛP enables harnessing available knowledge, learning emerging knowledge and continually creating new knowledge. It consists of an ontology-based, knowledge-assisted method and platform to capture, structure, configure and reuse knowledge for designing materials and engineering systems. The PREMΛP ontology provides extensible representation of data and knowledge. The semantic mappings of concepts in the ontology are used to draw inferences and provide pro-active guidance while designing manufacturing processes and selecting parameters to meet the product specification that addresses a given engineering problem. We show how the ontological models can help in (a) automating process design starting from a …
