The COIN-OR Cup Award Goes to Auckland!
by Ana-Iulia Alexandrescu
The COIN-OR community had its annual award ceremony to reward the best contribution to the COIN-OR suite at the Fox and Hound on Sunday evening. COIN-OR (Computational Infrastructure for Operations Research) is an initiative to promote the development of open software, models, standards, and data sets for the operations research community, and it involves members from both academia and industry. Pietro Belotti, the Chair of the Award Committee, delivered the announcement, and this year's award went to Andrew Mason from the University of Auckland and Iain Dunning, currently at MIT Center for Operations Research, for OpenSolver, a linear and integer optimization solver for Microsoft Excel. OpenSolver harnesses the power of the COIN-OR CBC optimization engine and is compatible with Excel 2003, 2007, and 2010. Neither Andrew nor Iain could attend this year's meeting, so the award---a cup full of coins---was accepted by Ted Ralphs on their behalf. In his speech delivered on Andrew's behalf, Ted highlighted the rapid traction OpenSolver gained in the O.R. community, going from 0 downloads 18 months ago to roughly 30 downloads per day currently. He also mentioned the release of the beta version of OpenSolver Studio, which allows users to use Excel maneuver models built using the Python-based PuLP modeling language, which provides a more elegant solution for modeling complex optimization problems. The ceremony was sponsored by IBM and was held in a laidback atmosphere, providing everyone the opportunity to relax after the first day of the conference.
Bringing Operations Expertise to the Healthcare Industry
by Belleh Fontem
The past two decades have witnessed the metamorphosis of operations research purely as a discipline for analyzing manufacturing and supply chain processes to one that also lends huge expertise to the service sector. A domain that has greatly benefited from this trend is the healthcare industry. In the United States, healthcare spending alone is rapidly approaching a fifth of GDP, and unless drastic improvements in efficiency are achieved, accelerating healthcare cost inflation is not expected to vanish anytime soon.
Several graduate students attending this year's INFORMS conference are working on tough, intractable problems, some of which have plagued the health industry for decades. At the healthcare poster session on Monday, the students displayed their research questions as well as the results. Their research interests span a wide spectrum. Some are concerned with mitigating the impact of unexpected events. Valerie Chase at the University of Michigan, for instance, is developing forecasting methods to predict arrivals to the emergency room, whereas Georgia Tech's Jacqueline Griffin is using simulation to effectively allocate resources in a hospital maternity ward. Others are more into developing good performance metrics. Abigail Wooldridge at the University of Louisville has developed a productivity standard that captures both patient wait times and resource utilization.
Still others use advanced analytic tools to explore decisions that have repercussions for the treatment of progressive diseases. North Carolina State University's Muge Capan is using Markov chains to optimize treatment costs for Alzheimer's disease, and Daniel Underwood, also from NC State, is using a similar approach to find optimal solutions to the problem of determining appropriate test thresholds for prostate cancer.
After the restaurant and professional service operations (e.g., banking), healthcare is set to be the next big beneficiary of new insights and techniques that are continuously being discovered and invented by the operations research community.
Promoting the O.R. MINDSET
by Ana-Iulia Alexandrescu
Project MINDSET is a five-year initiative funded by a $3 million National Science Foundation grant to promote the development of analytical and mathematical modeling skills among senior high school students. The project addresses a widespread problem in U.S. secondary education---namely, students' difficulty with word problems, multistep solution approaches, and analyzing and interpreting the solution and results obtained. Project MINDSET started in North Carolina as a result of the historically high value the state places on mathematics education. Today, as a result of the committed efforts of Ken Chelst from Wayne State University, David Goldsman from Georgia Tech's ISyE Department, and other highly motivated and very involved individuals, the program has grown and spread over three states: North Carolina, Michigan, and Georgia. At present, there are 220 teachers that use the materials developed by Chelst's group and teach 2,000+ high school students topics, ranging from deterministic linear and integer optimization and applications in transportation and facility location and assignments, to decision trees, Poisson processes, and queuing theory. The novelty rises not only from the areas explored, which complement the traditional calculus and geometry curriculum, but also from the approach used, which highlights scenario-based learning, providing fun problems that are relevant and interesting to students, such as selecting the most cost-effective family phone plan and deciding which colleges to apply to or choose. Extensive feedback from students and teachers suggests a change in the attitude of students toward math and a heightened ability of teachers to capture their students' interest and engagement in the classroom. Though successful where implemented, this "grassroots" movement faces tremendous challenges stemming from the lack of visibility and the risk and absence of incentives for teachers to reform the math curriculum. In areas where the academic O.R. community has lent its support, such as in Georgia and North Carolina, the teachers have embarked on the initiative with a high degree of success; they themselves have become excited about introducing these tools to the students. This points to the local academic institutions as having a great power to influence the high school math curriculum and significantly change the MINDSET of the students. Note: For his contribution to the society, his vested interest in promoting education, and his work with the MINDSET project, as well as his close ties with the industry, Chelst was awarded the prestigious INFORMS President's Award yesterday evening.
The Emergence of Big Data
by Belleh Fontem
In laying out a vision for the future of data analytics, Keith Collins, CEO and Senior Vice President of SAS Software, used Ray Kurzweil's singularity concept (the accelerating pace of technology and the eventual merging of man and machine) as an analogy for a point in the distant future when data mining and modeling will converge in a seamless construct.
Globalization and the advent of the of the knowledge economy have resulted in a huge data deluge with important consequences for the competitive dynamics of the data analytics industry. There is an inundation of data in almost every industry conceivable, and although the average number of transactions per person remains fairly static, the attributes of those doing these transactions are in a state of constant flux. To respond to the challenges induced by these changes, companies such as the one Collins leads are moving from a product-centric business approach to a customer-centric one. For example, SAS clients in the consumer retail, banking, healthcare, and utilities industries now place more emphasis on supporting services that come with the data analysis applications rather than the applications themselves. In essence, they have realized that business analytics can be an important lever for competitive advantage, thereby forcing SAS to move from a pure analytics company to a solutions company. Moreover, for companies like SAS, the shortage of experts is putting upward pressure on the cost of selling these services.
Given the growth in the strategic importance of data analytics, Collins said that companies operating in his industry could not afford to look at data in the same manner. To prepare for the future, his company is focusing on the three pillars of high performance: computing, creating intuitive visualization capability, and applying text analytics to unstructured data.
He mentioned that the roots of SAS lie in academia and that the data analytics industry continues to rely heavily on organizations such as INFORMS to nurture talent and drive research, which is effectively the required fuel for innovation.
Why Good Simulations Go Bad
by Ana-Iulia Alexandrescu
The International Honor Society of Operations Research and the Management Sciences, Omega Rho for short, has inducted Barry Nelson, the Walter P. Murphy Professor and Chair of the Department of Industrial Engineering and Management Sciences at Northwestern University, as their 45th Honorary Member. He gave a high-level overview for simulation non-experts on the beauty and pitfalls of simulation models, highlighting several categories for consideration. Beginning with his own first exposure to simulation with a numerically integrated system of differential equations modeling a dog chasing a runner in his early years of college, and drawing on a plethora of examples ranging from a heart project, to a newsvendor problem, to the Jai-Alai Spectacular 7 Scoring system, to queues, Nelson did a wonderful job presenting the challenges of building good, useful simulation models. He addressed problems that arise from misrepresenting risk, using antiquated tools in building experiments, and misinterpreting the results; he provided several demos to prove his points. He furthermore stressed the importance of asking the right questions and building accurate and truthful statistical models to ensure the usefulness and truthfulness of the simulation. In the Q&A session, Nelson gave his opinion on the direction of the field, remarking the tremendous potential arisen from the development of analytics and conjecturing that the marriage between vast amounts of data and simulation tools is where the research in simulation is heading.

The Social Media Session Rocked
by Paul Rubin
The afternoon panel session on social media for O.R. was standing-room only. Thank you to everyone who took time to attend (including resident skeptic Irv Lustig, who kept us at least somewhat grounded). Props to Tim Hopper, who didn't flinch at being the one student on a panel loaded with extinguished faculty (and Bjarni K., the Wotan of Web 2.0).
