About

Sung Il Kwag is a leading researcher in the optimization of service robotics and logistics systems, with a particular focus on the hospitality and tourism sectors. His most influential work, "Optimal capacity and operation design of a robot logistics system for the hotel industry" (2019), has garnered 55 citations and stands as a cornerstone in the field. In this study, Kwag pioneered a mathematical framework to determine the ideal number of robots and their operational schedules for in-hotel delivery tasks, directly addressing the critical balance between service efficiency and capital investment. This contribution has provided hoteliers with a data-driven blueprint for integrating autonomous logistics, reducing labor costs while enhancing guest experience. Beyond this, his broader research explores the intersection of operational research, artificial intelligence, and sustainable tourism, aiming to automate repetitive tasks without compromising service quality. Kwag’s work is notable for its practical, industry-ready models that bridge the gap between theoretical optimization and real-world deployment. For students and researchers, his research offers a compelling case study in how quantitative methods can solve complex, human-centric challenges in the emerging robot-augmented service economy.
