Bellow Stack Manufacturing Ontology

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

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

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
