摘要：It is an effective approach to achieve solutions for new engineering changes by retrieving and reusing existing cases. An ontology-based retrieving method for engineering change was proposed in manufacturing enterprises. Three steps of change case retrieving were proposed on the basis of eigenvector representation of change case and extension of retrieval requirements. Then, retrieving requirements and similarity calculation method was studied. Finally, the algorithm was validated with a change case of tensile testing machine components. © 2013 Chinese Automation and Computing Society in the UK - CACS.
