WORK EXPERIENCES

•   Prediction-Based Intelligent Manufacturing for optimizing scheduling, dispatching, and job assignment tasks

Samsung Electronics, Korea, (January 2017 – August 2020)

Proposed and developed the anticipatory systems to minimize the production facility idleness and reduce human intervention for the abnormal events in plants. Managing the large-scale automation system is too tough and labor-intensive; thus, they are not sufficiently optimized by the deterministic and rule-based approaches. We successfully employed several predictive systems in the real-world applications such as scheduling, dispatching, and job assignment tasks in manufacturing fields. The success story on artificial intelligence-based control system is relatively rare in production sites. This is because that several difficulties exist to adopt AI-based systems in production sites; low resource learning problems, the highly coupled system of systems, unsafe data-driven approaches for decision making, rare abnormality, and non-stationary conditions data problems and so on. We thus pursue to 1) define the problem solved by data analysis, 2) build the robust and sustainable AI systems, and 3) collaborate with domain experts to consider about stable operation plans. It's very encouraging to obtain a successful AI-based decision-making system in consideration of all practical issues.

• Material Handling Automation in Fabrication

Samsung Electronics, Korea, (March 2014 – August 2020)

Analyzed the performance of automated material handling operation at semiconductor fabrication; developed mathematical/analytical models to improve the performance of automated material handling system; developed the OHT (Overhead Transport) Control System and Stocker Control System.

•   Manufacturing Monitoring and Optimization System Development in Electrical Die Sorting

Samsung Electronics, Korea, (July 2012 – June 2013)

Initiated the mega project in which the developed system provided monitoring, analyzing and optimizing functions for EDS manufacturing lines. The loss of asset utilization of equipment is visualized in Gantt Chart and the mathematical model provide the optimal production planning, now for more than 200 operators.

•   Evaluation and Approval for manufacturing operation regarding automation efficiency and effectiveness

Samsung Electronics, Korea, (June 2010 – August 2010, April 2014 – November 2014)

Announcing the flexibility of the manufacturing system relative to the variability of production demands. Especially, I focused on evaluating the capacity planning   performance with regard to the severe bottleneck facilities. We suggested the multiple criteria and developed an innovative method which can be robustly applied in  various production environments of the semiconductor manufacturing.

•   Factory Layout Design and Improvement

Samsung Electronics, Korea, (November 2011 – December 2014)

As part of the Manufacturing Modeling and Simulation Analysis Research project, developed the manufacturing simulation and analysis tool to design factory layout and improve the manufacturing operation, which had been applied in affiliated overseas manufacturing lines.

•   Developing High Fidelity Simulator-Based on Discrete Event Simulation for Material Handling System

Samsung Electronics, Korea, (April 2010 – December 2013)

To support production scheduling decision making, developed a sophisticated modeled simulator for semiconductor manufacturing system. The simulator was modeled by discrete event simulation concepts and used to obtain optimal decision making by considering both production and material handling systems.

•  Enterprise Data Integration (EDI) Software Development

TmaxSoft, Korea, (July 2008 – February 2010)

Participated to develop an architectural solution for various industrial system interactions by developing an enterprise service bus (ESB)-based solution. The solution aims at providing abundant services such as process automation, protocol processing, and rule combinations to facilitate data transfers and obtain the service orchestration. I focused on developing the enterprise application integration (EAI) adapter, including HTTP-, WEBDAV-, SAP-, SWIFT-, and so forth.

• Developing Web-Based Monitoring System  for IT System Administrator

TmaxSoft, Korea, (January 2007 – June 2008)

Developed the administration system based on web applications for the commercial products. The system was built on the conventional web frameworks such as struts, jsf, ajax, and spring stuffs.
