A Core Theory Leading Academia and Industry for 20 Years: First Korean Researcher to Receive the ‘Test-of-Time Award’

A research achievement that has served as a global standard for both academia and industry in the field of real-time systems for the past 20 years has once again been recognized for its immense value. Professor Insik Shin of the KAIST School of Computing received the ‘Influential Paper Award 2025’ at the IEEE Real-Time Systems Symposium(RTSS), the most prestigious international conference in the field. This marks the first time a Korean researcher has received this honor.

The RTSS Most Influential Paper Award is a ‘Test-of-Time Award’ presented to research that has exerted a continuous and profound influence on both academia and industry for more than 10 years after its initial publication. The award ceremony took place at IEEE RTSS 2025 held in Boston, USA.

The award-winning paper is the ‘Periodic Resource Model’ study, co-published by Professor Shin in 2003 with Professor Insup Lee of the University of Pennsylvania. This research moved away from the traditional method of verifying complex real-time systems as a single entity. Instead, it proposed a new theoretical framework that first verifies whether individual modules within the system meet their specific time constraints. It then guarantees that the safety of the entire system is maintained when these modules are combined.

This approach allows systems to be verified at the component level—much like assembling LEGO blocks—and has been evaluated as structurally overcoming the limitations of modern real-time system design, where complexity has increased exponentially. This theory has served as a core analytical tool in fields where even a momentary delay cannot be tolerated, such as autonomous vehicles, aerospace control systems, and industrial robots.

A Standard in Global Textbooks: Elevating the Status of Korean Computer Science

Even at the time of its release in 2003, this paper garnered significant attention by winning the Best Paper Award at RTSS. Over the following 20 years, it has become a foundational study in real-time scheduling theory, utilized consistently in both research and industrial settings. Currently, it is featured in textbooks at major universities in the United States and Europe and is taught as a standard theory in the field.

The IEEE Technical Committee evaluated the study as functioning as the “core language” of modern real-time system design, leading the direction of academia and industry for two decades. This award is seen as a prime example of the international standing of Korean computer science research, as it officially recognizes long-term impact rather than short-term results.

From Foundational Theory to AI Innovation

Regarding the award, Professor Insik Shin expressed that it was the honor he most desired as a scholar, stating it is a privilege to be recognized for research from 20 years ago that has had a meaningful impact on actual industry and society. He added that the contributions of researchers and companies who applied the theory to real-world systems were significant.

Meanwhile, Professor Shin is expanding his research beyond real-time systems into the field of Artificial Intelligence(AI). He is currently attracting attention from both academia and industry for bridging foundational theory with applied technology, such as developing mobile AI agent technology through a faculty-led startup.
