Bellow Stack Manufacturing Ontology IE 500 Final Project Xinnan Peng Department of Industrial and System Engineering
Scope of Project Ontological representation of a certain manufacturing process Categorize data under the structure of ontology
Application of the project ontology Part of knowledge base Other parts: Finite Element Analysis (FEA); Design of Experiment (DOE); Operator knowledge representation etc. Standardize to be applied for other products Extend to other manufacturing processes
Existing Ontologies MAnufacturing's Semantics Ontology (MASON) by Lemaignan et al. “drafting a common semantic net in manufacturing domain” Not on BFO Widget manufacturing ontology, by Ron Rudnicki. Part-Focused Manufacturing Process Ontology (PMPO) by Lucas Mesmer
The process
Terms and relations – in an Excel spreadsheet
Structure of Ontology Highest level: Basic Formal Ontology (BFO) developed by Dr. Smith and Dr. Grenon Provided a clear structure
Structure of Ontology Assign entities into classes
Structure of Ontology Lower level: Process example
Check the structure of Ontology – the true path rule Use is_a to link subclass and its parent class Example: Forming press
Add axioms
Structure of Ontology Add axioms Object properties that links the classes together
Structure of Ontology Add axioms cont. Example: Forming press
Future work Incorporate other ontologies into the knowledge base Implement into data collecting module Finalize with detailed definitions
