ISEM was extremely honoured to have Prof Lui Pao Chuen with us on 14 April to share his views on energy security and defense strategies for Singapore.

Prof Lui has served in the Ministry of Defence for 41 years in various key capacities, including 22 years as Chief Defence Scientist before his retirement in 2008. He continues to contribute his expertise professionally to numerous committees in universities, government agencies and corporations.

Prof Lui presented a comprehensive overview of Singapore's approach to energy security, covering three main areas: defense, energy sources, and climate change adaptation, giving our attendees valuable insights to practical strategies that enhance resilience and ensure reliable, sustainable energy supply for Singapore.

The Science of Better: An Introduction to Operations Research

Have you ever wondered how ride-hailing apps route drivers instantly? How does Singapore manage thousands of ships at the port? How do tech companies train AI efficiently? The answer is Operations Research (OR). OR uses math and data to help us make the best possible decisions with limited resources.

Join the Department of Industrial Systems Engineering and Management (ISEM) for a clear, introductory online lecture. We will explain Linear Programming—a basic math tool in OR—and show how it solves real-world problems: Local Logistics, Global Shipping, Healthcare, and Future Tech. If you enjoy math, computer science, and solving practical problems, this lecture will show you how OR connects them all to make a direct impact on society.

Date: 25 April 2025 (Sat)
Time: 11am - 12pm
Speaker: Dr Wang Guanyi, Assistant Professor, ISEM Department
The workshop will be held through Zoom meeting.

This year, 22 dedicated student teams spent the past 9 months working hand-in-hand with industry partners such as Micron, SingHealth, and Singapore General Hospital, and also faculty advisors to come up with practical and innovative solutions for real-world challenges across diverse sectors.

Our students showcased a great amount of versatility as they are faced with such technical industry problems, as they were well-trained in various skillsets such as streamlining logistics operations, improving resource planning, and enhancing decision-making through data analytics. It is also evident that their success would not have been possible without the students' hard work and teamwork, as well as their mentors' guidance.

Through the Systems Design Project module, students gained valuable pre-work experience, applying industrial systems engineering knowledge in real-world environments. In turn, ISEM’s industry partners benefit from impactful solutions and the opportunity to connect with a talented pool of future-ready engineers.

We can't wait to see what the future batches of ISE engineers will continue to contribute in the world beyond NUS.

This study examines assortment and inventory optimization in a two-warehouse e-commerce system that aims to balance delivery speed and cost efficiency. The system consists of a front-end warehouse, strategically located near customers to support rapid order fulfillment but constrained in inventory capacity, and a back-end warehouse, which holds a larger inventory but incurs higher fulfillment costs and longer shipping times. We model this setting as a joint assortment and inventory optimization problem, where initial assortment and inventory decisions are made for the front-end warehouse before demand is realized. Once orders are placed, the e-commerce firm determines the quantity of each order type to fulfill from the front-end warehouse. The marginal distributions of each order type are known, while the correlation structure of the joint distribution is unknown. We formulate the problem using the Marginal Distribution Model (MDM). As MDM is not directly tractable, we propose an approximation that relies solely on marginal distributions and provides valid lower and upper bounds for the original problem. We further investigate conditions under which these bounds are tight. Additionally, we show that the joint assortment and inventory optimization problem is NP-hard, even under simplified settings with deterministic demand and single-item order types. To address this computational complexity, we develop a heuristic algorithm to facilitate efficient assortment decisions. Numerical experiments based on simulated data demonstrate that our proposed policies achieve a favorable balance between optimality and computational efficiency.

In Singapore, energy security is more than an economic or a social concern—it is a matter of national defence. It must be treated as a large-scale integrated defence system, linking infrastructure, fuel imports, nuclear options, and climate policy. Critical nodes such as energy terminals, LNG supply chains, and digital power grids require physical protection, redundancy, and cybersecurity. Heavy reliance on imported natural gas leaves Singapore exposed to geopolitical shocks, making diversification through regional electricity trade (ASEAN Power Grid), solar deployment, and low-carbon fuels strategically vital—but also introducing new interdependence risks. Emerging nuclear technologies, particularly small modular reactors, offer potential for long-term strategic autonomy. Yet they bring trade-offs: limited land, safety margins in a dense environment, waste management, public trust, and regional diplomacy. In short, Singapore’s energy defence requires integration as a large-scale system. Protecting infrastructure, diversifying energy sources, and carefully exploring nuclear options are all essential to safeguard energy security while minimizing climate impacts.

DAO-ISEM-IORA Seminar Series presents ✨

Mission-oriented R&D programs such as those at DARPA and ARPA-E increasingly shape national innovation portfolios, yet their design and evaluation are typically inferred from aggregate outputs — publications, patents, and spinouts which reveal little about how programs actually organize and coordinate innovation. This talk develops a network-science framework for analyzing the structural organization of challenge-led R&D programs. Representing programs as typed networks linking researchers, organizations, and knowledge outputs, Prof Ho applies motif-based graph analysis to recover the local coordination structures assembled by program directors and to test longstanding hypotheses in innovation management about how ARPA-style programs assemble capabilities, coordinate projects, and generate spillovers across innovation ecosystems.
