ities breathe, thrum, and lurch forward in fits of brilliance and chaos. Beneath their gleaming skylines lies a pulse made of sirens, traffic lights, subway delays, and a hundred systems just seconds from strain. Ambulances caught in gridlock, dispatch centers flooded with calls, power grids flirting with overload—modern urban life is a symphony conducted with missing notes. Each decision, from resource allocation to emergency response, echoes across a labyrinth of interdependencies. Yet despite all our technological sophistication, some of the most vital public systems still function on intuition, habit, and hope. The cost of inefficiency isn't just inconvenience—it's measured in lives, dollars, and the silent accumulation of missed opportunities. Amid the static of overloaded systems and the hum of misfiring networks, Richard Larson has made a career of tuning chaos into clarity. He doesn't just

operations research, and technology-enhanced education. In addition to his scholarly contributions and institutional innovations, Richard left behind a legacy of countless lives enhanced by his commitment to linking theory and practice. The Making of a Systems Thinker Richard was born in Bayside, Queens, a neighborhood tucked within the rhythm of New York City. Raised in a household where learning was celebrated and curiosity encouraged, he developed an early fascination with how everyday systems functioned. His childhood included several relocations, eventually leading him to graduate from Needham High School. From there, he set his sights on MIT, where he would go on to earn his Bachelor's, Master's, and Ph.D. degrees in electrical engineering by 1969. During his time at MIT, the institution was a hotbed of innovation in applied sciences and mathematical theory. Immersed in this charged academic environment, Richard found himself influenced by some of the leading figures in operations research. More than just mastering equations and algorithms, he came to deeply value the idea of turning abstract concepts into tools that could solve pressing, realworld challenges—a guiding principle that would shape the course of his entire professional life. Contributions to Operations Research Over the span of his prolific career, Richard Larson has either authored, co-authored, or edited six books and contributed more than 175 peer-reviewed articles. His work spans a wide array of domains, including emergency services in urban environments, disaster response strategy, infectious disease modeling, queuing theory, logistics systems, techenhanced education, energy-efficient housing, and workforce analytics. One of his earliest and most influential contributions, Urban Police Patrol Analysis (published by MIT Press in 1972), received the esteemed Lanchester Prize from the Operations Research Society of America—an early sign of the impact his work would have. Later, he collaborated with Amedeo Odoni on Urban Operations Research (Prentice Hall, 1981), a seminal textbook that continues to be widely

referenced, having amassed over 1,000 citations. Richard's innovative research into queueing systems has earned both national and international recognition. Among his landmark achievements are the Queue Inference Engine, a pioneering application of data analytics long before the term became mainstream, and the Hypercube Queueing Model, which has been cited extensively in academic literature. In addition to publishing, Richard has been a wellknown leader in his industry. He presided over INFORMS (2005), the Institute for Operations Research and the Management Sciences, as well as the Operations Research Society of America (1993–1994). He also spent over 15 years as co-director of MIT's Operations Research Center, helping shape the next generation of researchers and thought leaders. The field of public policy has also made use of his experience. Serving on U.S. government advisory bodies, such as the Standing Committee on Emergency Management and Medical Response Integration (2009–2015) and the Institute of Medicine's Board on Health Sciences Policy (2008–2010), allowed him to contribute to national projects. His consulting work has informed major operational improvements for the U.S. Postal Service and the City of New York. The Mission Behind the Honors Richard has received many accolades for his outstanding achievements. The INFORMS President's Award, the George E. Kimball Medal, and the inaugural Daniel Berg Lifetime Achievement Medal in 2017 are just a few of the honors bestowed upon him in recognition of his contributions to strategic planning, public service systems, and technical innovation. Between 1995 and 2003, Richard led MIT's Center for Advanced Educational Services (CAES), where he championed the integration of digital learning into higher education. His vision extended globally with the creation of LINC (Learning International
www.businessmindsmedia.com
Networks Consortium), which brought together educators from around the world for dialogue and collaboration through a series of international symposia. Today, Richard continues his mission to expand access to quality education as the principal investigator of MIT BLOSSOMS—an open-source learning initiative focused on science and mathematics. He remains active in research, particularly in developing operations research frameworks to address large-scale challenges such as pandemic response and educational reform in the United States. Education That Transcends the Four Walls Richard was renowned as a teacher for fusing rigorous academic instruction with hands-on, experiential learning. He avoided a purely "theoremproof" approach because he thought that students studying operations research needed to experience real systems in order to have an intuitive understanding of them. His own classes at MIT required students to apply analytical techniques to complex, unstructured situations through field research, case studies, and group projects. Richard's influence extended much beyond the classroom. He mentored numerous PhD students during his career, including Kent W. Colton and Maia Majumder, who have achieved distinguished careers in academia, business, and government. His genuine concern for his pupils' professional and personal development, as well as his commitment to fostering moral responsibility and intellectual curiosity, were hallmarks of his mentoring. Richard managed off-campus consulting firms such Public Systems Evaluations, Inc. and ENFORTH Corp. in addition to his teaching responsibilities. These companies allowed students to spend their summer breaks working on real projects, typically in challenging urban environments like New York City. Many students were inspired to pursue fulfilling careers in operations research and related subjects after being exposed to working on field operational difficulties.
012
Mentorship, to me, is about encouraging curiosity, embracing failure as part of the process, and never letting complexity scare you away from a problem worth solving.
Reforming 911 from the Inside Out Richard Larson played a critical role in overhauling New York City's emergency call system, turning a once-disjointed process into a far more responsive and efficient operation. Before the 911 system was implemented, New Yorkers were required to dial different numbers based on their borough—an arrangement that often led to confusion and costly delays in times of crisis. Even after the centralized 911 service was introduced, significant issues remained, particularly with long caller wait times. To tackle these persistent inefficiencies, Richard partnered directly with NYPD lieutenants and dispatch teams to investigate the underlying problems. Through detailed data analysis and handson collaboration, he pinpointed weaknesses in operator deployment and scheduling. His recommendations led to significant operational changes that dramatically shortened response times. While hard data on the exact life-saving outcomes may not exist, Richard is confident that these improvements had a meaningful impact on public safety. Perhaps just as important, he meticulously recorded the strategies and systems used during the

overhaul, laying the groundwork for other cities to adopt similar reforms in their own emergency response infrastructures. Championing Global Learning Access through CAES From 1995 to 2003, Richard Larson led MIT's Center for Advanced Educational Services (CAES), where he spearheaded the development of digital learning platforms aimed at reaching learners around the world. Under his guidance, the center focused on breaking down geographical and institutional barriers, making high-quality education more accessible to diverse populations. The pioneering efforts at CAES became a springboard for many of the online and blended learning advancements later adopted at MIT and other institutions globally. Launching LINC: A Worldwide Educational Alliance In 2002, Richard took his commitment to educational equity a step further by founding the Learning International Networks Consortium (LINC) at MIT. This global initiative was designed to harness the power of technology to scale education effectively and ethically. Bringing together academic institutions, government leaders, and practitioners from over 25 countries, LINC created a platform for collaboration and innovation. Through global conferences and strategic partnerships, the consortium championed the use of digital tools—such as e-learning platforms and ICT solutions—to improve educational opportunities for

underserved and remote communities worldwide. Pioneering Work in Queueing Theory and Urban Systems Richard Larson's body of research spans a remarkable breadth, yet remains deeply rooted in practical impact. From the fundamentals of queueing theory to the dynamics of urban systems and service engineering, his contributions have reshaped how complex networks—like emergency response and public transportation—are understood and optimized. What sets his scholarship apart is its balance of academic rigor and real-world relevance. Whether read by scholars or industry professionals, his work offers clear insights grounded in interdisciplinary thinking and accessible application. Bringing Models to Life for Everyday Decision-Making In recent years, Richard has focused his attention on helping everyday people harness the power of analytical thinking. His latest book, MODEL THINKING for Everyday Life: How to Make Smarter Decisions—published by INFORMS—introduces readers to the dual meaning of "model": as a conceptual tool and as a standard to strive for. Richard encourages readers to engage deeply with problems using logical reasoning and structured thinking rather than relying on rote knowledge or digital shortcuts. His message is simple but powerful: slowing down, asking better questions, and using simple models can

How
Data-Driven Models Improve
I
n the quiet hum of city life, beneath the traffic lights, sirens, metro schedules, and garbage routes, algorithms are hard at work. They're not always visible, but they help decide where ambulances go, how traffic lights change, when buses arrive, and even how schools and hospitals allocate resources. As cities become increasingly complex and densely populated, data-driven models—rooted in operations research and systems analytics—are stepping in as powerful tools to improve efficiency, equity, and responsiveness in public services. The Rise of the Smart City The term "smart city" often conjures images of futuristic buildings, autonomous cars, and sensors embedded in every corner. But the real backbone of a smart city is its ability to make intelligent decisions based on real-time data. This shift is powered by algorithms that process enormous streams of information and convert them into actionable insights.
018
These algorithms—some powered by AI, others by traditional optimization techniques—aren't theoretical experiments. They are actively reshaping how cities function. From sanitation to emergency response, they are helping governments tackle urban challenges with speed and precision. From Congestion to Coordination: Managing Urban Traffic Traffic congestion is one of the most visible—and frustrating—urban challenges. Traditionally, traffic flow was managed using fixed schedules for traffic signals and educated guesses based on historical data. But now, cities like Los Angeles and Singapore are adopting adaptive traffic control systems that respond to real-time conditions. These systems use machine learning algorithms and queuing models to adjust signal timing, reroute vehicles, and prevent bottlenecks before they occur. The result? Reduced congestion, shorter travel times, and lower
emissions. Algorithms are also being used to manage ride-sharing fleets and coordinate public transportation schedules, creating a more seamless and integrated urban mobility experience. Emergency Services: Every Second Counts In public safety, every moment matters. Data-driven models help emergency services—police, fire, and medical teams—respond more quickly and effectively. Algorithms can predict high-demand zones using historical incident data, enabling proactive stationing of ambulances or patrol cars. Queueing theory, a foundational concept in operations research, helps balance resource allocation across neighborhoods to ensure optimal coverage and minimize response times. In New York City, for instance, improvements in 911 operations and dispatcher algorithms—guided by data—have significantly improved emergency response performance.

Waste Management and Utilities: Cleaner, Smarter Cities Even systems as routine as garbage collection and water usage benefit from smart modeling. Cities like Copenhagen and Amsterdam use sensor-equipped bins to detect fill levels, allowing collection routes to be dynamically updated. This minimizes unnecessary trips, reduces fuel consumption, and saves public money. In utilities, predictive models forecast energy or water usage spikes based on weather, time of day, and historical demand. These insights enable utility providers to balance load, prevent outages, and manage costs—all while improving sustainability. Education and Health: Equity Through Algorithms Beyond physical infrastructure, algorithms are also improving humancentered services like education and healthcare. For example, school district planning can be optimized using geographic and demographic data to balance enrollment, reduce overcrowding, and improve access to quality education. In public health, cities are increasingly using real-time analytics to detect outbreaks, track vaccination rates, and deploy mobile clinics where they are needed most. During the COVID-19 pandemic, data-driven models played a crucial role in determining hospital capacity, testing locations, and vaccine distribution strategies. Ethics, Equity, and Transparency However, the growing role of algorithms in city governance raises important questions: Who designs these algorithms? What data are they trained on? And do they reinforce
020
existing inequities? Without careful oversight, even well-intentioned models can unintentionally prioritize efficiency over fairness. For instance, predictive policing algorithms have come under fire for perpetuating bias when trained on historically skewed data. Similarly, resource allocation models must account for marginalized communities that may not generate as much digital data but have greater needs. To address this, cities must prioritize ethical modeling, ensure transparency in algorithmic decision-making, and include community voices in the design process. Public services should serve everyone—not just those easiest to quantify.
increase. Data-driven models are no longer a futuristic luxury—they are a civic necessity. From routing ambulances to reducing pollution, optimizing classrooms to anticipating water demand, algorithms are the invisible engines making modern cities livable, scalable, and more humane. The challenge now is to wield this power with responsibility, ensuring that technology enhances—not replaces—human judgment and public accountability. The algorithms of the city are here to stay. The question is: Can we design them not just to optimize our systems, but to elevate our society?
Toward a Model-Driven Public Sector The future of urban governance is not just digital—it's algorithmic. But success depends not only on smart technology, but also on smart leadership. Public officials must be educated in data literacy, and interdisciplinary teams—combining engineers, urban planners, sociologists, and ethicists—should guide implementation. More importantly, the public must understand and trust the models that shape their lives. This means making algorithms interpretable, auditable, and adaptable—so they can be refined as conditions evolve and as community values shift. Conclusion: Modeling a Better Tomorrow As urban populations grow and infrastructure strains under pressure, the demand for intelligent, responsive, and equitable public services will only

e have all waited in line—at the bank, in traffic, at a hospital, or on hold with a customer service center. These moments, though often frustrating, are more than just pauses in our day. They are reflections of how systems function, how resources are allocated, and how time is valued. Behind every queue is a decisionmaking process. And behind those decisions lies a powerful tool: queueing theory. Though it may sound technical, queueing theory is one of the most practical fields in applied mathematics and operations research. It studies the formation, behavior, and management of queues. But more than that, it helps public services deliver on their promise of efficiency, fairness, and accessibility. What Is Queueing Theory? At its core, queueing theory is the science of waiting lines. It models how entities—people, vehicles, data packets, or requests—arrive at a service point, how they are prioritized, how long they wait, and how quickly they are served. It factors in

randomness, variability, and limited resources, aiming to optimize the performance of systems under pressure. Developed initially to solve problems in telecommunications, queueing theory has evolved into a critical framework for public policy, healthcare, transportation, and emergency management. Its value lies in its ability to predict bottlenecks, improve service delivery, and ensure that finite resources are used in the smartest possible way. Healthcare: More Than Just a Waiting Room In hospitals and clinics, the stakes of waiting are high. A delay in treatment can worsen outcomes, increase patient anxiety, and overload staff. Queueing theory helps administrators analyze patient flow, manage triage protocols, and design scheduling systems that minimize wait times while maximizing care quality. Emergency departments, in particular, rely on these models to prioritize cases based on urgency and availability of staff or equipment. During the COVID-

the redesign of New York City's 911 call system, which used queueing models to reduce hold times and improve emergency coordination.
Transportation: From Gridlock to Flow
From visa applications to tax offices, queueing theory is also shaping the experience of citizens engaging with government services. Long lines at public agencies can signal deeper inefficiencies—understaffing, outdated scheduling systems, or poor infrastructure. Models that predict peak hours, simulate demand patterns, and optimize staffing levels can dramatically reduce public frustration.
Urban transportation systems are perhaps the most visible manifestations of queueing in everyday life. Traffic congestion, subway delays, bus wait times—all are influenced by queuing dynamics. By modeling intersections, vehicle flow, and rider demand, cities can better manage transit schedules, reduce congestion, and improve commuter satisfaction. Adaptive traffic signal control systems use real-time queue data to adjust light patterns dynamically, allowing smoother flows and reduced wait times. In public transit, queueing models help planners determine where to add capacity, how to optimize routes, and how to maintain service during peak demand or disruptions. Emergency Services: Saving Time to Save Lives For fire departments, police units, and ambulance services, every second saved in response time can mean the difference between life and death. Queueing theory assists in optimizing the placement of emergency vehicles, balancing workloads among dispatchers, and planning coverage across neighborhoods. By simulating different scenarios—like a surge in 911 calls during a natural disaster—public agencies can test response strategies and improve resource readiness. One of the most transformative examples of this was
026
Government Services: Efficient, Fair, and Transparent
Virtual queues and appointment-based services, powered by queueing algorithms, are now replacing traditional lines, offering users transparency and predictability. These improvements not only boost satisfaction but also reflect a more respectful and inclusive approach to public service. Beyond Efficiency: Ethics in Queueing While queueing theory is a tool for efficiency, it also raises important ethical questions. Who gets served first? How are priorities determined? Can optimizing speed come at the cost of fairness? In healthcare, should younger patients get priority in critical care? In transportation, should traffic systems prioritize buses over private cars? In government services, how do we ensure equal access for those with disabilities or limited digital literacy?
systems don't simply reduce wait times; they reflect the values of the communities they serve. The Future of Queueing Theory in Public Life As cities grow, systems become more digital, and services move online, queueing theory is evolving too. Realtime data from sensors, mobile apps, and cloud platforms allows for dynamic queuing models that adjust instantly based on current conditions. Artificial intelligence and machine learning are being integrated to enhance predictions and improve responsiveness. From airports to call centers, the goal is no longer just to manage queues, but to anticipate them—and in some cases, eliminate them entirely. Conclusion: More Than a Line Queueing theory may start with lines, but it ends with systems—systems that touch every part of daily life. It empowers public servants to make better decisions, helps cities run more smoothly, and improves access to critical services for all. When done right, queueing theory becomes more than mathematics. It becomes a form of respect. Respect for people's time, for equitable service, and for thoughtful design. In the world of public service, that's a line worth standing in.
These questions show that queueing is not just a technical issue—it's a social one. And the best queueing

Smarter Systems for a Faster World
in a Real-Time
World

n an age defined by immediacy, where decisions are made in milliseconds and data flows in torrents, the field of Operations Research (OR) stands at a critical inflection point. Traditionally rooted in optimizing complex systems through mathematical models, OR has long been a behind-the-scenes powerhouse, quietly shaping military logistics, public health responses, and industrial efficiency. But the future is no longer about slow, retrospective analysis. It's about real-time adaptability, dynamic decision-making, and smart, self-correcting systems. A New Pace for an Old Science Operations Research emerged in the mid-20th century as a strategic science—deployed in World War II to optimize radar placement, convoy movements, and resource allocation. Over time, it spread to manufacturing, healthcare, transportation, and public services. But for much of its history, OR operated on a retrospective model: gather data, build a model, simulate scenarios, and then implement a plan. In today's digital world, that cadence feels outdated. We now live in a "realtime world," where GPS reroutes us mid-commute, emergency rooms
028
reprioritize patients as data updates, and supply chains shift instantly based on weather, labor shortages, or global demand. The future of OR lies in abandoning the wait-and-plan model and embracing one that's continuously sensing, learning, and acting. Real-Time Challenges Demand RealTime Solutions What makes the future of OR so promising—and so challenging—is the sheer volume, speed, and variety of available data. From IoT sensors in smart cities to transaction logs in ecommerce platforms, the data streams never stop. This explosion of data means that operations research must now function more like a nervous system than a filing cabinet. Take urban mobility systems, for instance. Traffic optimization once meant simulating patterns and adjusting light cycles every few months. Now, cities need OR models that ingest real-time sensor data, detect anomalies instantly, and recalibrate traffic signals on the fly. In such environments, static optimization gives way to adaptive, data-driven control systems. Healthcare is another example. Hospital capacity planning has always
involved complex modeling—but the COVID-19 pandemic showed how quickly conditions can change. Forecasts built on last week's numbers were rendered obsolete in hours. The new frontier for OR in healthcare is predictive resource allocation that updates by the minute—matching patients, beds, staff, and equipment in an ever-changing environment. Marrying OR with AI and Machine Learning To keep pace with this real-time shift, Operations Research is increasingly merging with artificial intelligence (AI) and machine learning (ML). This synergy is transforming traditional OR models from rigid tools into adaptive systems. Machine learning provides the predictive horsepower—recognizing patterns and anomalies in vast datasets. OR, on the other hand, supplies the decision logic—establishing constraints, optimizing trade-offs, and ensuring system efficiency. Together, they enable "prescriptive analytics": not just forecasting what might happen, but recommending the best course of action in that moment.
www.businessmindsmedia.com
029
www.businessmindsmedia.com
In warehouse logistics, for example, real-time inventory levels can be continuously monitored and paired with ML algorithms that predict demand surges. OR models then optimize staffing, routing, and restocking strategies dynamically—delivering precision and efficiency simultaneously. The Rise of Streaming Analytics At the heart of real-time OR is a technology called streaming analytics—the ability to process and analyze data in motion. Unlike traditional batch processing, which analyzes data in chunks after it has been collected, streaming analytics evaluates data the moment it arrives. This allows operations systems to respond in real time, sometimes even before a human can intervene. For OR professionals, this means building models that are not only accurate but lightweight, fast, and robust under constant change. It also calls for closer collaboration with data engineers and system architects who design the infrastructure to handle realtime flows. Human-in-the-Loop: Still Essential Despite these technological advances, the future of operations research isn't purely autonomous. The most effective systems still incorporate human-in-theloop decision-making. While algorithms may detect patterns or anomalies, human judgment remains essential for context, ethics, and interpreting ambiguous situations. This is especially true in areas like public policy, disaster response, or medical triage, where stakes are high and the data may be incomplete or biased. OR systems in the future will
030
act more like copilots—surfacing insights, suggesting actions, and allowing humans to make the final call. Looking Ahead: Real-Time Ethics and Equity As OR becomes faster and more powerful, new ethical questions arise. Real-time systems can optimize for speed and efficiency, but what about fairness and transparency? How do we ensure that optimization doesn't disproportionately disadvantage vulnerable populations? For example, an emergency response system that prioritizes calls based on historical patterns might unintentionally under-serve marginalized communities if the input data reflects past inequities. The future of OR must therefore integrate ethical modeling, bias detection, and equityaware optimization as core components—not afterthoughts. Conclusion: A Living Discipline The future of Operations Research is not confined to static models or once-ayear simulations. It's evolving into a real-time, intelligent decision engine—one that continuously adapts, learns, and acts. This shift demands not just faster algorithms, but a new mindset: one that embraces uncertainty, fluidity, and constant feedback. OR in a real-time world is no longer a backstage discipline. It's a frontline tool for resilience, agility, and innovation. And as systems grow more complex and interconnected, its importance will only grow.
