Welcome to LST Lab.

Welcome to Stochastic Systems Lab. in the Department of Industrial and Management Engineering at POSTECH.

Our mission is to develop efficient and effective methodologies for the analysis and optimization of large-scale stochastic systems. Research topics include but are not limited to

• Queueing Theory and Stochastic Processes,

• Stochastic Simulation,

• Time Series Foundation Model and its applications,

• Optimization under uncertainty with pre-trained models,

• Reliability and Data-Driven Quality Control,

POSTECH 산업경영공학과 확률시스템 연구실(LST Lab.)에 오신 것을 환영합니다.

LST Lab.에서는 불확실성을 내포하고 있는 시스템의 성능분석 및 최적운영에 관한 연구를 수행하고 있습니다. 연구주제는 다음과 같습니다.

• 대기이론, 확률과정

• 시뮬레이션

• 시계열 파운데이션 모델 및 응용

• 사전학습 모델을 활용한 불확실성 반영 최적화

• 신뢰성 및 데이터 기반 품질 관리
