Thoroughly Enjoyed Giving the Opening Keynote at the Mexican OR Society Conference
I was very intrigued by this invitation and eager to return to Mexico especially since I had lived in Tulancingo, Mexico the summer between high school and college. I had won a national Spanish exam in the US and was invited to go there and to live with a family as part of the Experiment in International Living. The experience was very special, so I accepted the invitation to speak at this conference.
I headed to Bradley Airport at 5AM last Tuesday and had two very pleasant flights on Delta, with the connection in Atlanta. I was graciously met at the airport and driven to my hotel, which was very close to ITAM Santa Teresa, the venue of the conference. The views from my hotel room, which was on the 29th floor, and the neighboring area by the elevators, were spectacular.
Shortly after my arrival, I made my way to the conference site in order to get my bearings and I liked the auditorium very much as well as the gardens and flowers.
Welcoming remarks for the opening of the conference were made by Dr. David F. Muñoz Negrón of ITAM, the President of the Scientific Committee, and Dr. Elías Olivares Benítez, the President of the Mexican OR Society. I was introduced by Dr. Luis A. Moncayo Martínez of ITAM, who was President of the local Organizing Committee.
Interestingly, Dr. Moncayo Martínez had been to my Omega Rho Distinguished Lecture at the 2019 INFORMS Conference in Phoenix!
Many of the scientific talks were in Spanish so this gave me a great opportunity to practice a language that I love and, I must admit, I understood about 85% of what was said, and was even able to ask intelligent questions. What very much impressed me was the passion of the speakers, who clearly enjoy the research that they are doing and also enjoy in communicating it. It was wonderful to meet new professional colleagues and many students, as well. It was fun to be asked to be photographed with them, in addition.
In my keynote, which I have made publicly available, I included several photographs of luminaries in our profession, including one of Professor George Dantzig of Stanford, who has passed away, and who I so enjoyed conversing with during many conferences over the years. I hoped to energize and inspire the audience with my talk. I focused on advances in Operations Research in the form of networks and game theory for applications such as: congested urban transportation networks and the Braess paradox, perishable product supply chains from food to healthcare, cybersecurity, and disaster relief. The work on disaster relief was co-authored with a former student of mine, Emilio Alvarez Flores, an Isenberg School of Management and UMass Amherst Commonweath Honors College alumnus, who is originally from Mexico. He now works for Cisco and we communicate regularly. I also discussed some very recent research on global trade networks and the impacts of tariffs and quotas, with a case study on avocados from Mexico. The latter research was conducted with my doctoral student Deniz Besik. Deniz and I have, with co-authors, published a series of papers on the very timely topic of tariffs, quotas, and trade wars in such journals as the Journal of Global Optimization (the issue is to be featured at the Springer booth at the INFORMS 2019 conference that is now taking place in Seattle), Transportation Research E, and the European Journal of Operational Research.
I mentioned in my keynote that I became interested in trade policy instruments, when I was approached by a group of agricultural economists, researching the dairy industry, from Cornell University two decades ago, who wanted to collaborate on ad valorem tariffs focusing on Mexico! And, together, we published a series of paper. Hence, looking back, Mexico has permeated a nice amount of my research, spearheading both advances in methodologies as well as applications.
No conference would be complete without wonderful social engagement and, last Wednesday, after my keynote, I was treated to one of the most delicious lunches in my life at the restaurant Sylvestre. At the lunch were: Dr. Jose Blanchet of Stanford University (another keynote speaker and ITAM alum), Dr. David F. Muñoz Negrón and Dr. Luis A. Moncayo Martínez as well as Dr. Beatriz Rumboz, a Dean at ITAM who holds 2 PhDs, as well as Dr. Erick Centeno-Morena. The food, ambience, and conversations were all exquisite!
And we topped our delicious meals with a portfolio of desserts, which we shared.
I very much appreciate all the logistics arrangements for me and the outstanding hospitality.
It was also marvelous to hear from the conferees about many mutual friends in our profession, which is global in scale, but always feels local, because of the strength of ties.
I would like to wish all the members of the Mexican Society of Operations Research much continuing success in all of you endeavors and, again, I thank the society and the organizers of this conference for being such exemplary hosts! I returned to Massachusetts with many wonderful new ideas, powerful impressions, and new personal connections, which I value very much.
It was also great to hear that, while in Mexico, I received a book contract from Springer to edit another volume on Dynamics of Disasters, with a focus on risk and resilience, with my fellow co-editors, Professors Ilias S. Kotsireas and Panos M. Pardalos!

Presenting on Supply Chain Networks for Disaster Relief in Greece
The paper that I will be presenting is on our lated research on disaster relief supply chain networks: A Mean-Variance Disaster Relief Supply Chain Network Model for Risk Reduction with Stochastic Link Costs, Time Targets, and Demand Uncertainty, Anna Nagurney and Ladimer S. Nagurney.
The paper goes further than our earlier paper, An Integrated Disaster Relief Supply Chain Network Model with Time Targets and Demand Uncertainty, Anna Nagurney, Amir H. Masoumi, and Min Yu, in Regional Science Matters: Studies Dedicated to Walter Isard, P. Nijkamp, A. Rose, and K. Kourtit, Editors, Springer International Publishing Switzerland (2015), pp 287-318, which Amir will be presenting at the EURO Conference in Glasgow, Scotland in July. In our new paper, the model that we construct is the first to integrate disaster preparedness and response in a supply chain network framework with a mean-variance (MV) approach for risk reduction under demand and cost uncertainty and time targets plus penalties for shortages and surpluses.
The MV approach to risk reduction dates to the work of the Nobel laureate Harry Markowitz (1952, 1959) and is still relevant in finance, in supply chains, as well as in disaster relief and humanitarian operations, where the focus, to-date, however, has been on inventory management. Our new model handles both the pre-positioning of relief supplies, whether local or nonlocal, as well as the procurement (local or nonlocal), transport, and distribution of supplies post-disaster. In the paper, we provide numerical examples for an island nation and also a case study focusing on storms hitting Mexico.
The presentation can be downloaded here.
The program for the conference can be downloaded here. I am very much looking forward to the exchange of ideas at what should be a very interesting, focused conference. Two of my former doctoral students, both of whom are very successful professors now, Dr.. Tina Wakolbinger and Dr. Fuminori Toyasaki, will be presenting at this conference. Also, it will be wonderful to see Dr.. Nurcu Balcik again, whose work with Dr. Benita Beamon, the students in my Humanitarian Logistics and Healthcare class at the Isenberg School get to read.
Many thanks to the University of Florida, Wilfrid Laurier University and the Isenberg School of Management for support! The Isenberg School has provided folders plus name tag holders and they have arrived in Greece,

World Cup Postcard from Argentina -- 1 Month and 1 Day
On June 11, 2010, the 2010 World Cup began and that was the same day that we mailed a postcard to ourselves from Buenos Aires, Argentina, where I spoke at the ALIO-INFORMS conference.Remember that today is July 12, 2010, the day after the ending of this World Cup in South Africa. I am pleased to report that the postcard that we sent to ourselves (since we love to track how long deliveries can take) arrived today! It took 1 month and 1 day and, strangely enough, it had a side trip to Mexico. Perhaps it was because Argentina beat Mexico in this World Cup?!
We started getting messages from relatives and friends in the past 10 days or so that our postcards to them from Buenos Aires were trickling in.
I wish that there had been a GPS tracker on this card because I am sure that the journey that it took was fascinating from a transportation point of view.
Above is what we are calling our infamous World Cup postcard. We whited out our address, which was present, so that was not the excuse for this extreme snail mail delivery.
At least it did arrive, finally!

2010 Edelman Prize Goes to Mexico's Indeval!
According to the press release: Indeval, the Mexican Central Securities Depository for all financial securities, manages Dali, the Securities Settlement System (SSS) that now has as its core an operations research engine.
Dali settles securities operations that average over $250 billion daily, more than 70% of the value settled in the Mexican payments system. Thus, an amount close to the Mexican gross domestic product (GDP) is settled in five operating days. Thanks to the [linear programming] model, many transactions that would remain pending if they were processed individually are settled together, thus reducing liquidity requirements dramatically – by 52% in cash and 26% in securities. The most important benefit of the implementation of O.R. in Indeval’s SSS is the enhancement and strengthening of the Mexican financial infrastructure.
This is another terrific example of how operations research and analytics can transform enterprises, institutions, and, even, nations!
More information about the recipient of this prestigious award, for which there were 6 finalists this year, can be found here. Past Edelman Prize winners include such household name institutions as: HP, Memorial Sloan Kettering Cancer Center, Merrill Lynch, Motorola, and IBM.
More information about INFORMS (Institute for Operations Research and the Management Sciences) can be found on its homepage.
Congratulations to Indeval and to all those who participated in this year's Edelman Prize competition!
