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.
