A new implementation of OntoSTEP for flexible generation of ontology and knowledge graphs of product model data

December 10, 2021

Author(s)

Soonjo Kwon, Laetitia Monnier, Raphael Barbau, William Z. Bernstein

Barbau et al. (2012) propsoed OntoSTEP that enables the translation ofthe STandard for the Exchange of Product Model Data (STEP) schema andits instances to an ontology and a set of knowledge graphs represented in theWeb Ontology Language (OWL). OntoSTEP

Feasability and Performance Analysis of Automating Engineering Change Requests

August 18, 2021

Author(s)

Michael Sharp, Thomas D. Hedberg Jr., William Z. Bernstein, Soonjo Kwon

Engineering change is a non-value-added activity that happens as a product progresses through its lifecycle. Engineering change is a significant cost sink in many projects. While avoiding and mitigating the risk of change is the ideal approach, mistakes

Part Decomposition and Evaluation Based on Standard Design Guidelines for Additive Manufacturability and Assemblability

November 19, 2020

Author(s)

Yosep Oh, Hyunwoong Ko, Timothy A. Sprock, William Z. Bernstein, Soonjo Kwon

In comparison to traditional manufacturing, Additive Manufacturing (AM) has facilitated the production of complex part geometries. However, AM suffers from its own limitations, such as the need for support structures, presence of the stair-step effect and

Enriching Standards-Based Digital Thread by Fusing As-Designed and As-Inspected Data Using Ontologies

August 13, 2020

Author(s)

Soonjo Kwon, William Z. Bernstein, Laetitia V. Monnier, Raphael Barbau

Realizing the digital thread is essential for linking and orchestrating data across the product lifecycle in smart manufacturing. Linking heterogeneous lifecycle data is critical to maintain associativity and traceability in a digital thread. Recently

An automated workflow for integrating sustainability assessment into parametric part design through standard reference models

August 6, 2020

Author(s)

William Z. Bernstein, Melissa Tensa, Maxwell Praniewicz, Soonjo Kwon, Deverajan Ramanujan

Integrating environmental sustainability assessment into parametric design represents an important opportunity for enabling sustainable product design. However, this is a challenging task as quantitative methods for sustainability assessment are poorly

Standardizing environmental performance evaluation of manufacturing systems through ISO 20140

August 6, 2020

Author(s)

Hitoshi Komoto, William Z. Bernstein, Soonjo Kwon, Fumihiko Kimura

Standards play a critical role in the realization of more sustainable practices in manufacturing systems. This is especially critical considering the trends in digitization and virtualization of production systems. More data is being generated at
