BLOG ON: OR/MS Forecast: Sunny days for the Cloud
by Marc-Andre Carle
Cloud computing is everywhere this year. A lot of researchers are proposed parallel algorithms for many applications. The Cloud is also quite the hype with software vendors. Gurobi, CPLEX and Sulumn, among others, have announced or are already shipping distributed computing algorithms for solving mathematical programming problems in the cloud. You can thus build your model on your laptop and then distribute the workload of solving the model on one or more servers.

MONDAY'S INTERACTIVE SESSION WINNER
Congratulations to Mohammad Marufuzzaman for winning the Monday Interactive Session competition.
Poster Title: Impact of different carbon regulatory policies in biofuel supply chain network under uncertainty.
"This poster presents a two-stage stochastic programming model that is used to design and manage biodiesel supply chains. This is a mixed-integer linear program, and an extension of the classical two-stage stochastic location-transportation model. The model proposed optimizes not only costs, but also, emissions in the supply chain. The model captures: the impact of biomass supply and technology uncertainty on supply chain related decisions; the tradeoffs that exist between location and transportation decisions; and the tradeoffs between costs and emissions in the supply chain. The objective function and model constraints reflect the impact of different carbon regulatory policies, such as carbon cap, carbon tax, carbon cap-and-trade, and carbon offset mechanisms on supply chain decisions. We solve this problem using algorithms which combine Lagrangian relaxation and L-shaped solution methods, and we develop a case study using data from the state of Mississippi. The results from the computational analysis point to important observations about the impacts of carbon regulatory mechanisms; as well as the uncertainties, on the performance of biocrude supply chains."

WORMS Session on Women Authors
|(L to R): Basak Kalkanci, Guzin Bayraksan, Özlem Ergun|
By Amy Pielow
Women in OR/MS sponsored a session Monday featuring presentations by women authors of papers in top OR journals that covered a variety of topics: sequential sampling procedures in stochastic programming, network design in liner shipping, and pricing games in decentralized assembly systems.
Güzin Bayraksan, professor at The Ohio State University, presented first on a sequential sampling procedure for stochastic programming. The method determines the number of samples necessary to solve stochastic programming problems to a given level of optimality by progressively adding samples to the optimization problem. Rules for stopping were also discussed. Under certain conditions, the algorithm is proven to converge with a probability of one in the limit of the confidence interval of the optimality gap estimator at least as large as a user-determined level.
The second presentation, by Özlem Ergun of the Georgia Tech, discussed carrier collaborations with resource sharing. Operational synergies are possible through cooperation of buyers and sellers via economies of scope. In particular, the researchers study containerized liner shipping in which assets (ships) are pooled among carrier companies. They design a mechanism to obtain solutions close to a centralized optimum despite decentralized decisions in a game theoretic framework. Behavior of companies is modeled as profit maximizing; side payments to shippers are used as incentives to obtain strategic, sustainable, and cooperative behavior.
Basak Kalkanci, also of Georgia Tech, closed the session with a presentation titled "Pricing Games and Impact of Private Demand Information in Decentralized Assembly Systems." The work combines decentralized assembly systems, common agency, and information asymmetry. Manufacturers who contract with multiple suppliers face more complexity than those who do not, but they also have private information unknown to any of the suppliers. Suppliers with limited information of demand may provide complex contracts to increase their overall benefits. This gain is achieved primarily through the supplier who contracts with the manufacturer first.
CAP® and Continuing Education
By Pelin Cay In CPMS, The Practice Section session, Jack Levis, director of Process Management at UPS, spoke about Certified Analytics Professional (CAP®) certification and Stephen Powell, Dartmouth College, informed the audience about INFORMS continuing education (CE).
Jack Levis began with the motivation behind the CAP® certification program and explained the program in detail. He stated that this certification program emerged in January 2010. The objective is to give certificate to practitioners as a way of proof for practitioners that they are capable of applying analytics, similar to how the Project Management Institution certification program proves project management skills. He explained that CAP® certification is developed according to standards for certification (ISO/IEC 17024). To be certified, the practitioners need to take a three-hour, timed exam consisting of 100 multiple choice questions where paper and pencil format is applied. However, passing the exam is not the only requirement to get the certificate. The practitioners should also satisfy at least 30 PDUs (professional development units) where one PDU corresponds to one hour of analytics-related activity.
Stephen Powell explained the objective of CE, which is building up analytics education for analytics professionals - separate from the CAP® program. He explained that CE can develop highly effective and practical education experiences for practitioners. Under the CE program, "Data Exploration and Visualization" and "Essential Skills for Analytics Professionals" workshops were organized in September and October this year. There will be one final "Essential Skills for Analytics Professionals" workshop November 7-8. Workshops will continue in 2014 as well. These workshops will be organized not only in the U.S. but also in Singapore and Hyderabad. Powell also stated that there will be new workshop topics such as "Data & Text Mining" and "Optimization Modeling." The INFORMS CE program is also planning to start online courses in 2014. Powell finished his talk with how you can support INFORMS continuing education:
- Sign up for CE workshops/online courses
- Encourage others in your network to do so
- Encourage your organization to get involved
- Volunteer to assist INFORMS CE committee
Data-Driven Operations Research Analyses in the Public Sector
By Pelin Cay
Lawrence M. Wein, professor from Stanford University, gave an OMEGA RHO distinguished lecture Monday. He discussed five studies that are applications of data-driven operations research analyses in the public sector. The common themes of these studies include:
- public policy problems;
- large longitudinal data set;
- exploratory data analyses guides model building;
- constraint optimization problem (trade-off curves); and
- comparing proposed policies to existing policies.
The first topic is about allocating blood for transfusions. Wein shared that five million people per year receive blood transfusions. In these transfusions the current policy is FIFO (first in, first out), among exact matches. The current system has national supply (donations) to demand (transfusions required) ratio which is 1.085, but there is also significant geographical variation. The research question for this study is whether there exists an allocation policy that is better than FIFO. Their approach to this question is to apply queueing model using single parameter policy to minimize outdates. They had a chance to test the model with Cleveland Clinic and American Red Cross for six months. The results show the impact of switching FIFO to LIFO (last in, first out) depends on supply and demand in the system. The predicted benefit of the policy is to reduce annual deaths by 20,000 in the U.S.
Wein's second topic was screening and treatment for childhood obesity. He explained that there are both universal and targeted approaches to fight obesity. Targeted approaches are screening based on BMI, and treatment (dietary, physical activity, and behavioral consulting) by the U.S. Preventive Sources Task Force (USPSTF) and an expert committee from 15 professional organizations. Wein looks for an optimal screening (and treatment) policy that outperforms the existing policies. His method is applying discrete dynamic programming such that the objective is minimizing diseases, hypertension, and Type 2 diabetes. When the optimal policy is compared to USPSTF, there is a 3% relative reduction in disease and 28% relative reduction in cost, and compared to the expert committee, there is a 6% relative reduction in disease and 40% relative reduction in cost.
The third topic was the improvement of ballistic imaging performance, which uses the images of cartridge casings and bullets from crime scenes that are then uploaded to a database. The proposal is to enhance the performance by using extraneous data, i.e., applying the model to cartridge casings and bullets in the U.S. Wein's model decreases the false negative rate.
The next topic was about food allocation for childhood malnutrition, which is a major problem in Africa. Wein mentioned that 1 out of 8 children dies before the age of 5 in Africa. Nearly half of those deaths are a result of undernutrition. There are metrics to define the undernutrition, such as weight for height z-score (WHZ) and height for age z-score (HAZ). There are two foods available for treatment of undernutrition: ready to use therapeutic food (RUTF) and ready to use supplementary food (RUSF). The research question is how NGOs and governments allocate and organize food aid under restricted funds. Wein uses population-wide evolution of HAZ and WHZ data set for their model. They also use randomized clinical trial data to estimate impact of treatment and logistic regression to estimate death rate as a function of age, sex, HAZ, and WHZ. They optimize over proposed class of policies to minimize disability-adjusted life years (DALYs) subject to food aid budget constraint. The proposed policies versus benchmark policies show 9% reduction in expected DALYs at same expected cost, and 61% reduction in expected cost at the same expected DALY.
In the final topic, Wein gave the insight of the study that is optimizing the biometric aspects of India's universal identification (UIDAI) program. They proposed a policy for this program and showed that when the individualized policy is implemented to store different subset of subimages, they are able to reduce false rejection rates significantly.
The Physics of Target Guests
By Anwesha Bhattacharjee
Mark von Oven, director of marketing analytics and reporting at Target, engaged his audience with physics parallels to marketing, tracking the forces that have altered the retail market.
It was important for Target to be able to keep its target audience wanting to come back each time, particularly because it is a discount retail store. "Target has built its reputation in surprising you," von Oven said.
Target is characterized by its closeness to the community and they have been expanding globally into India and Canada. Despite his past experience working at P&G, which is already a global brand, working to expand a national chain into a global chain was a learning experience for von Oven. With the new generation of millennials, the way stores target and "speak" to guests is changing, he said.
Just like gravity, electromagnetism, and nuclear forces redefined physics, transactions, web and mobile apps, and social interactions have become the primary forces of holding on to guests, von Oven said. The idea in retail now is to speak to the guests, and social forums that Target has released to its customers allow guests to share their thoughts and desired Target shopping experience. Target has also come out with a new app that will allow guests to scan the barcodes of the product and share the items later with their friends. While this allows guests to buy things for a lower price and make their experience easier, it also benefits Target by revealing the guest's friends on social networks and knowing how to predict their behavior in store beforehand.
Now the analytics are becoming important not just in terms of the answers but also what questions to ask, von Oven said.
2013 Edelman Award Reprise
By Amy Pielow
According to Kees Roos, professor at Delft University of Technology, "absolute protection against flooding is impossible." He made the statement to a packed auditorium during the 2013 Franz Edelman award reprise on Monday. Three researchers accepted the award on behalf of the Dutch Delta Program Commissioner: Kees Roos, Dick den Hertog of Tilburg University, and Jarl Kind of Deltares. INFORMS President Anne Robinson presented the award. The Franz Edelman Award for Achievement in Operations Research and the Management Sciences is awarded to organizations utilizing operations research, management science, and advanced analytics in pioneering and transformative ways.
Susceptibility to flooding in low-lying areas is common throughout the world, as are extreme flood events, including a 1953 devastating flood in the Netherlands. Since then, the population of the nation has doubled, two-thirds of whom live in flood-prone areas. Motivated by this risk, and the lack of consensus in recommendations, researchers on an interdisciplinary, multiorganization team spent five years and €4 million on a model for investment in flood dike upgrades throughout the Netherlands. Monday's event featured a multimedia presentation of the award-winning work.
The model, a mixed-integer nonlinear program, considers a 300-year time horizon with binary investment and continuous upgrade decisions every five years. Results from the model imply dramatic reduction in expected costs compared to no change and prior recommendations. The analysis shows that current dikes range from more than sufficient given flood likelihoods to insufficient and in need of investment in three areas. Overall, based on the model's solution, the expected costs of investment and flood damage would decrease €7.8 billion for government policies through 2050.
Panel Discusses INFORMS' Expansion Into Analytics, Merits
By Anwesha Bhattacharjee
INFORMS Past President Terry Harrison, Penn State, Nicholas Hall from Ohio University, and Barrett Thomas from the University of Iowa, jointly led a panel discussion Monday morning on "OR, Analytics and the Academic: The Path Forward."
As a prelude to the discussion, Harrison pointed out trends in analytics membership in INFORMS, which dipped in 2009 and then increased sharply post 2011, as did attendance in INFORMS spring meetings. He attributed the upward trend to the branding of the word analytics.
INFORMS has decided to expand into analytics without compromising the core competencies of the organization, partly because in more than 30 years, this is the most financially stable the organization has been, Harrison said. He provided a clear definition for analytics, which most members who took a CapGemini survey said was closely related to OR but not the same thing. "I disagree with the statement that analytics can be anything to anybody," Harrison said.
One of the ways INFORMS will realize its vision of becoming the leading organization for advanced analytics, Harrison said, is the analytics maturity curve. Hall said in context of the maturity curve leaning more toward prescriptive analytics, that analytics solutions tend to be automated and the potential value may be greater because of the greater range of techniques and the focus on broader problems.
Thomas spoke briefly about the motivation and design of a new analytics undergraduate major at the University of Iowa, and students from their first batch said employers hired them uniquely on the basis of a business intelligence course that they took.
In answer to questions from the audience if analytics is a fad, Hall said that analytics was here to stay because it is something novel, which is what academics want, and is at the same time useful, which is what businesses want. "This is a marketing campaign driven by a strong product," Hall said.
