1. Bellow Stack Manufacturing Ontology IE 500 Final Project Xinnan Peng Department of Industrial and System Engineering

2. Scope of Project Ontological representation of a certain manufacturing process Categorize data under the structure of ontology

3. 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

4. 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

5. The process

6. Terms and relations – in an Excel spreadsheet

7. Structure of Ontology Highest level: Basic Formal Ontology (BFO) developed by Dr. Smith and Dr. Grenon Provided a clear structure

8. Structure of Ontology Assign entities into classes

9. Structure of Ontology Lower level: Process example

10. Check the structure of Ontology – the true path rule Use is_a to link subclass and its parent class Example: Forming press

11. Add axioms

13. Structure of Ontology Add axioms Object properties that links the classes together

14. Structure of Ontology Add axioms cont. Example: Forming press

15. Future work Incorporate other ontologies into the knowledge base Implement into data collecting module Finalize with detailed definitions

16. QUESTIONS?
